The best boiling water taps and hot water taps

1. Quooker Fusion

Best boiling water tap: with a childproof double push and turn switch with red LED warning light ring to alert you when your tap is in boiling mode, this Nordic-design boiling water tap is a no-brainer


Best for: Style-conscious Tank capacity: 3ltrs or 7ltrs Temperature range: True 100ºC boiling Finish: Polished chrome, brushed chrome, stainless steel, black and gold. Other Quooker models include Flex, Classic and Nordic single

Reasons to buy

+Child-friendly +Stylish+Hot, cold, 100ºC boiling and filtered cold water from a single tap+Saves time, water and energy

Reasons to avoid

-Not available off the shelf from multiple location chain high street DIY stores, but via 3,000 kitchen dealer partners or the Quooker website-Expensive

Ideal for those who want a boiling water tap which looks good, but still want it to be safe around the kids and of course, practical; the Quooker Fusion is definitely one of the best boiling water taps you can buy.

Why we like it

As with all Quooker boiling water taps, you can choose your tank size depending on your personal usage, and you can select add-ons like a soap dispenser, scale control and a mounting bracket.

What it does well

It has a childproof double push and turn switch, and delivers boiling water in an aerated spray to avoid any accidents. There’s also a cold filtered drinking water option, and our favourite part is the red warning light ring which illuminates when boiling water is heating up or being dispensed.

What to watch for

Not necessarily something that should put you off, but do bear in mind that Quooker taps are expensive. Prices for the Fusion start from £1,150. Quooker also provides a single boiling water tap which starts at £950. You can also opt for a Combi tank which mixes boiling and cold to provide ordinary hot water, supplying all temperatures from just one cold feed.

2. Abode PT1105 Pronteau 3-in-1 Prostream Monobloc Instant Boiling Water Tap

Best hot water tap: this copper hot water tap will add elegance to any kitchen

Best for: Elegance Tank capacity: 2ltrs Temperature range: Up to 98ºC Finish: Chrome, Brushed, Graphite, Copper & Matt Black Finishes +Range of finishes to suit all kitchens+Hot water is filtered+Affordable -Tank capacity is small

It looks gorgeous annnd it’s affordable. It comes in a range of different finishes – chrome, brushed nickel, graphite, mat black and copper, so you will definitely find something to suit your space.

What is does well

With a capacity of two litres, this gorgeous hot water tap is ideal for smaller households. Through its elegant swan-neck, the tap delivers domestic hot, cold and filtered hot water up to a temperature of 98ºC. In terms of ease of use, the tap can be rotated 360ºC for accessibility, and it always remains cool to the touch.

What to watch for

The only possible problem with this hot water tap is the small tank capacity.

3. QETTLE 4-in-1 Instant Boiling Water Tap

Best boiling water tap for ease of use: this boiling water tap ticks all the boxes, and doesn’t have a high price tag

Best for: Ease of use Tank capacity: 4ltrs Temperature range: Up to 100ºC Finish: Chrome +LED light to let you know when filter needs changing+Tank reheats in just 10 mins+Affordable -Needs to be installed by a plumber

Delivering up to eight cups of boiling water at one time, the intelligently named Quettle delivers cold water, hot water and water at 100ºC in an instant.

Why we like it

This is probably the best boiling water tap for those who are eco-conscious. When the time comes to change the filter (the LED display on the tap will light up to let you know), it’s not only affordable, but the replacement filter cartridges are also recyclable.

What it does well

It’ll replace your current kitchen tap, and it has a four litre capacity. Also, if you do happen to drain the four litre boiling water tank, it’ll reheat in just 10 minutes. It’s safe for those with children as the tap has a safety clip, and the best part is that it costs only 3p a day to run when it’s on standby.

What to watch for

You will need to get a plumber to install the Qettle 4-in-1, but with anything involving water that’s probably no bad thing.

4. Stiebel Eltron Undersink Water Boiler and 3-in-1 Tap

Best hot water tap for safety: an ideal hot water tap for busy families

Best for: Safety Tank capacity: 5ltrs Temperature range: 65ºC-97ºC Finish: Chrome +Large water tank+3 in 1+Child lock -Big tank which would need to be in a cupboard if you don’t want it on display

This three-in-one (cold, hot and near-boiling) hot water tap by Stiebel will replace your current kitchen tap so that you can use a combination of (almost) boiling, mains cold and domestic hot water all from one tap.

Why we like it

We loved that there’s no surge during tapping, meaning no spluttering and risk of scalding yourself (or anyone else). With a large water tank capacity of five litres, you’ll be drinking tea all day, every day, and there’ll be no need to wait for it to heat up again.

What it does well

For those who have children, it’s also childproof as it has a push and turn handle for the almost-boiling water to come out. You can also choose your preferred temperature on the dial on the tank, which ranges from 65ºC to 97ºC.

What to watch for

The tank is pretty bulky, so bear in mind you are going to need to space to store it if you don’t want it out on show.

5. Mayfair Escala Instant Boiling Water Kitchen Tap 3-in-1

Best budget hot water tap: for those who don’t want to spend an arm and a leg but still want boiling water at an instant

Best for: Budget Tank capacity: 2.4ltrs Temperature range: 75ºC-98ºC Finish: Chrome +Has a digital tank+Affordable price -Smallish water tank

Not only will the Mayfair Instant hot Water Kitchen Tap 3 in 1 add a touch of style to your kitchen, but much like the others, it’ll also help you out when it comes to making your morning coffee, sterilising baby bottles or boiling pasta for your dinner.

Why we like it

The price. For a good quality hot water tap this model is much cheaper than most.

What it does well

Offering three different temperatures from one single spout, you can choose from hot, cold or boiling water. Although smaller in capacity than others (the water tank is 2.4ltrs) it can deliver plenty of water for a small household, and it only takes 10 minutes to heat up once it’s empty. The tank also has a digital screen to control the temperature of the boiling water, and to tell you the temperature the water is at the time. A budget tap which still manages to tick all of the boxes we think.

What to watch for

As we’ve mentioned the capacity is pretty small at just 2.4ltrs. Plus just be aware the carbon filter will need changing every 6 months to ensure your tap is running at optimum performance.

6. Insinkerator Filtered Tap

Best single-lever hot water tap: with a small tank and a streamlined design, this is our best for bijou kitchens

Best for: Single-lever Tank capacity: 2.5 litres Temperature range: Up to 98°C Finish: Chrome + Filtered water for a fresher taste – Smaller tank than others

The Insinkerator Filtered Tap is a compact and practical solution if you’re after a do-it-all model that won’t be too obtrusive in your kitchen.

Why we like it

The build quality and the overall look and feel of the Insinkerator definitely feels more premium than the price tag.

What it does well

While not a boiling water tap (although at 98ºC, it does get pretty close) the hot and cold functionality of the Insinkerator makes it a valuable, versatile addition sink-side, and the filter makes for a fresher taste, whether you’re enjoying a straight-up glass or a hot drink.

What to watch

The 2.5 litre tank of this Insinkerator filter tap is on the petite side compared to some of our other picks, but if you’ve been frantically doing the maths and worrying about making space for an oversized tank, this might be a good solution.

7. Franke Omni 4-in-1 boiling water tap

Best boiling water tap for families: Franke’s foolproof offering is great for family homes

Best for: Families Tank capacity: 4.2 litres Temperature range: Up to 100°C Finish: Chrome + Very easy to use + Sizable water tank – A bit slow to filter- Very expensive

Aptly named, the Franke Omni really does seem to do it all. It looks almost like a regular tap design but you soon discover that it’s got lots more going for it…

Why we like it

It’s a surprisingly rare example of a boiling water tap that really delivers on that just-off-the-boil promise with up to 100°C water straight out of the nozzle, and with a large 4ltr+ tank, the water just keeps on coming, perfect for making large pans of pasta and filling sizeable mop buckets.

What it does well

Reviewers loved how foolproof it was: with ergonomic handles for lefties and righties, easy installation, filter change alert lights, splash-proof function and child lock all commended, it looks to be a great all-rounder and the best boiling water tap for big and busy families.

What to watch for

There’s only one design available, but it’s pretty neutral so we reckon it will suit more households. Apart from that the only thing to overcome is the pretty hefty price tag, but you are buying from a high-quality, experienced brand.

8. Insinkerator 3-in-1 Steaming Hot Water Tap

Best hot water tap for temperature control: for instant hot (or warm) boiling water as you please at whichever temperature you like

Best for: Temperature control Tank capacity: 2.5 litres Temperature range: Adjustable from 88˚C – 98˚C Finish: Chrome, Rose Gold and Gold +Hot water is filtered+Available in a range of finishes and shapes+Safety features+Space saving compact design+2 year warranty -Regular hot and cold water isn’t filtered

We love the compact design of the Insinkerator 3N1 Steaming Hot Water Tap, plus we think it’s the best boiling water tap if you are looking for a model that allows you to completely control the temperature.

Why we like it

With the ability to dispense up to 100 cups of boiling water an hour, this hot water tap gives you the option to set the temperature to whatever you like, so whether you need it at its hottest for boiling veg or just a little warm for the baby’s bottle, it has a setting to suit everyone.

What it does well

The unobtrusive 2.5 litre tank fits easily under a sink to supply water at all temperatures, and all hot water that comes out is filtered, too. For those who are style-conscious, it’s available in two shapes and several finishes to complement your kitchen. In terms of safety, it has a push-lever safety mechanism to prevent accidents. Its best quality is by the far its adjustable thermostat, making it the best boiling water tap for temperature control.

What to watch for

Reviewers mentioned that it could be quite slow at dispensing larger quantities of water, so just be aware of that if you are going to be using it frequently for cooking. Although obviously it’s still going to be quicker than boiling a full kettle.

9. Grohe Red Duo

Best hot water tap for features: super-safe, super-shiny, and super-smooth, this one can deliver up to 5.5 litres of water

Best for: Features Tank capacity: up to 5.5 litres Temperature range: Up to 99°C Finish: Chrome + Loads of helpful functions + Two-step child lock + Large tank capacity – Takes up a lot of under-cupboard space

A super-safe hot water tap that boasts a stylish design and great build quality, the Grohe Red Duo deserves a spot in our round up of the best boiling water taps.

Why we like it

We liked that you can choose from either a 3 litre or 5.5 litre boiler, depending on requirements. You will, however, need space in your kitchen cupboard to allow for this to be installed.

What it does well

Available in four different designs, the Red Mixer Tap from Grohe makes both a stylish and functional addition to a modern kitchen. Two-step, child-safe activation and a release-to-stop model makes it one of the safest options available on the market and therefore perfect for a family home, while the option for an integrated hot and cold tap for make it the perfect replacement for a standard kitchen tap.

What to watch for

This can be an issue with a lot of boiling water taps, but reviewers did note that despite the insulated sides, parts of the tap did get hot to the touch.

10. Carron Phoenix Larunda 3-in-1 tap

Best hot water tap for filtered water: an affordable 3-in-1 hot water tap with a built-in water filter

Best for: Built-in water filter Tank capacity: 2.4 litres Temperature range: 98°C Finish: Chrome +Good safety features+3-in-1+Affordable+Water filter -Requires a minimum operating pressure of 1.5 to 5 bar-Only available in one finish

The Larunda 3-in-1 tap from Carron Phoenix is a sleek new tap that not only dispenses 98⁰C hot water, but also hot and cold water, all from one single tap.

Why we like it

Cleanliness. Thanks to its water conditioning filter, your hot water will always be free of sediment, odour and any unwanted particles.

What it does well

Its available in a chrome finish, the tap features a timeless swan-neck design to suit a wide range of kitchen styles. In terms of safety, it has a cool-touch spout and features a push-and-twist operation to protect against accidental activation of the steaming hot water function. Its 2.4 litre tank can sit neatly in a cupboard under the sink and, for a 3-in-1 tap with a built-in filter, the price tag is pretty low, sitting in the £500 bracket.

What to watch for

It is a little slow at dispensing large quantities of water in one go and a few reviewers mentioned that the temperature didn’t quite reach boiling. Also, it sometimes spits in use and parts of the tap get hot to the touch.

How to buy the best boiling water tap and hot water tap

What’s the difference between a boiling water tap and a hot water tap?

The difference between a hot water tap and a boiling water tap is pretty slight. Put simply, a boiling water tap produces water that’s reached 100ºC, while hot water taps tend to hit a maximum of about 98ºC.


The latest boiling water taps don’t just dispense instant hot water – they deliver mains hot and cold water, too. Although they can be retro-fitted, a boiling water or instant hot water tap is a high price tag item that’s probably best installed alongside a brand new kitchen, especially as you have to factor in the space beneath the sink for the tank, which can range from two litres to 11 litres (bear in mind that most kettles have a capacity of around 1.7 litres).

If you are going from two pillar taps to one boiling water tap, you will need a replacement kitchen sink with just one hole.

Temperature: why are some called boiling water and some called hot water taps?

While instant hot water taps are often referred to as boiling water taps, most boiling water taps might boil the water to 100ºC, but it’s delivered at 98°C (many have adjustable temperature settings). There are only a few taps that truly deliver boiling water.


Look out for designs that come with a filter to purify the water before it enters the boiler tank. This will not only remove prevent limescale build-up in the tank, but it will also make the water taste better.

Price: How much does a hot water tap cost?

Boiling water taps and hot water taps and boiler tanks start at around £500. A plumber can install the tap in the same way that they would any tap (although admittedly with more connections to filters and boiler tanks); the boiler tank often comes with a standard 13 amp plug that goes straight into the wall next to it.

Running costs

While a kettle costs around 2.5p per boil, Quooker says that their boiling water taps cost just 3p per day to run on standby. Quooker does not use boiler technology, but instead uses a unique patented vacuum flask tank, which holds water under pressure at 110°C, so that it is dispensed at a consistent true 100°C boiling.

Quookers and boiling water taps – are they worth it?

As the name suggests, boiling-water taps provide instant hot water without the need to switch on the kettle or boil a pan on the hob. They can be a smart and handy solution if you want to streamline your kitchen surfaces, or find using the kettle a hassle.

A boiling-water tap is a much more permanent addition to your kitchen than a conventional kettle or plug-in hot water dispenser, as it needs to be plumbed in alongside, or instead of, your standard kitchen-sink taps.

To help you decide whether a hot-water tap is for you, we’ve looked into the pros and cons, and how the costs stack up. Read on to find out more and get a breakdown of what the different brands offer. You can also jump straight to a particular section using the links below:

Why consider installing a boiling water tap?

Boiling water taps provide instant hot water on demand

The main advantage of these taps is that they provide hot water much more quickly and easily than a kettle.

They also make it simpler to use just the amount of water you need, as you can fill your mug or pan directly from the tap. Manufacturers reckon that this makes boiling-water taps more efficient than a kettle and therefore less expensive to run.

Other advantages include:

  • Childproof handles and insulated sides should help to avoid singed fingers
  • More streamlined worktops – you won’t need a kettle so you can save on worktop space.
  • People who have problems filling, lifting and pouring a conventional kettle may find a hot water tap easier to use.

If you prefer filtered water, most models will also remove harsh-tasting chemicals – and in some cases soften and aerate the water, too. So, if you aren’t keen on the water in your area, this could help to make it more palatable.

What are the downsides of installing a boiling-water tap?

The most obvious one is cost. The cheapest boiling water taps cost more than £500, and those that can dispense water at variable temperatures will set you back even more, with some costing well over £1,000.

Not all boiling water taps come with installation included in the price. Although you can install them yourself, it’s not necessarily straightforward, so you may need to factor in the cost of a plumber.

You also need to clean the tap and tank from time to time to keep them free of limescale. Most models also require regular replacement filters, which can significantly add to the ongoing cost.

Is a boiling-water tap cheaper to run than a kettle?

You’d expect anything that can keep water at boiling point would be expensive to run, but if leading brands, such as Quooker, Grohe and Franke, are to be believed then hot water taps can be more economical than your average kettle.

Quooker says that its taps cost 3p per day if left on standby. The cost of boiling a litre of water in a kettle is just over 2p. So, if you boil your kettle several times a day – if you’re having a brew in the morning, again when you get in from work, and before bed for example, then you do stand to save on your energy bills.

However, the high upfront cost of hot-water taps means that it will take you more than a lifetime to recoup your investment. We’ve done the maths, comparing upfront and ongoing energy costs to our cheapest Best Buy kettle, below.

Quooker hot water tap vs a kettle for price and running cost

If you want to save money, you’d be better off choosing an energy-saving kettle instead. These kettles have low minimum-fill levels – usually as little as just one cupful – to make sure you aren’t heating more water than you need to, and they’ll also switch off as soon as the water has boiled. Head to our guide on the best energy-saving kettles to see the ones we recommend.

Boiling-water taps: features to consider

A boiling-water tap doesn’t have to mean adding a second or third tap around your sink. There are different combination available:

  • Two-in-one taps – dispense boiling and cold water
  • Three-in-one taps – dispense hot and cold water, as well as boiling water
  • Four-in-one taps – dispense on-demand cold filtered water in addition to mains hot and cold water, and boiling water

Some even dispense fizzy water, for the ultimate in on-demand water.

Hot-water tap tank capacity

Boiling-water taps come with different-sized tanks. The smallest can hold around two litres of water, while the largest can hold as much as 11 litres. Unless you often need lots of water from your tap at once, one of the smaller tanks should do the trick.

Child-safe taps

Red-hot water in an instant could be dangerous, especially if you have children who are used to getting cold water when they use the tap.

Look out for taps with childproof handles and insulated sides that won’t get hot even when the water is flowing.

Boiling-water tap brands compared

We’ve pulled together the costs and specs for the main boiling-water tap brands to help you compare them. See how they stack up in our summary table below, and scroll down for a breakdown of each brand.

Quooker boiling-water taps

How much do Quookers cost?

Quooker prices start at £950 for its Nordic Round model, and go all the way up to £1,890. It will cost more if you want a different finish or tank, but installation is free.

Tap options

You can choose between a separate boiling-water tap with accompanying mixer tap, or the Quooker Flex or Fusion models which have a single tap for hot, cold and boiling water. All have built-in filters. The Flex has a pull-out flexible hose for reaching beyond the sink to fill things up.

Tank sizes

Quooker tanks come in three-litre, seven-litre and 11-litre sizes. There’s also a Combi tank that can be used to provide hot (50-60°C) water instantly, as well as boiling water.

Maintenance costs and replacement filters

There’s a filter built into the hot water tank, which can last up to five years. If you live in a hard water area you can also add a limescale-control unit for £245. Replacement filters for the limescale unit cost £90 and will need to be replaced every 24 months.

As for the filter in the tank itself, you could either get a Quooker engineer to service the tap and replace the filter for £150 or do it yourself with a kit for £30.

Quooker also sell a cold-water filter to make drinking water taste better. It’s available on the Flex and Fusion taps and needs to replaced every six months.

Insinkerator hot-water taps

How much do Insinkerators cost?

InSinkerator’s taps start at £549 without installation.

InSinkerator offers five different taps, including a three-in-one tap with cold, hot and steaming hot water for £729 including installation. All come with built-in filters.

Maintenance costs and replacement filters

InSinkerator recommends replacing the filter in its taps every six to eight months. A pack of two replacement filters is £89.

Franke boiling water taps

How much do Franke taps cost?

Franke taps are some of the most expensive – starting at £999 for the Minerva and going up to £1,500 for the Omni.

The Minerva is a three-in-one tap that provides hot, boiling and filtered cold water. The Omni range and the Minerva Mondial are four-in-one taps that give you everything the Minerva does, as well as cold water from the mains.

Franke taps come with four-litre water tanks.

Franke recommends replacing the filters every four to six months. There’s a warning light on the Omni tap that will flash red when you need to change your filters. Each replacement costs £38.

Roux Lifestyle taps

How much do Roux Lifestyle taps cost?

Famous chef Michel Roux Jnr’s kitchen company makes the Monaco hot water tap, which will set you back at least £996.

Roux Lifestyle makes one tap, the Monaco. It comes in four metallic variants, with the chrome version costing £996 and brass or gold costing £1,400. The boiler delivers whatever temperature it’s set to and there’s no combi boiler action to get both cold and hot water.

2.4 litres, with a touchscreen on the front that allows you to adjust the temperature up to 99°C.

The Monaco tap uses exotic-sounding nano filtration paper to keep the tank free of limescale and nasty-tasting chemicals. The paper should be changed every six months, and replacements cost £50.

Grohe hot-water taps

How much do Grohe taps cost?

Prices start from £800-£1000 without installation, depending on the model and design. Installation costs £250 and can be arranged through Grohe’s website.

As well as the different finishes, you can choose either a rounded or square design, and either a medium or large sized tank. Each version of the tap has a built-in filter. It also comes with a three-year guarantee (when registered), unlike most taps which only come with two-year guarantees.

There are two options for tank size: 3 and 5.5 litres. They are made of titanium to reduce limescale build up.

The Red Duo comes with the smallest of Grohe’s filters, which will need to be replaced around every six to nine months. Extras cost £64. There are also medium (£129) and large filters (£179), which will need replacing every 1,500 and 2,600 litres, respectively. The taps come with a counter you can use to keep track of when your filter needs to be changed.

Abode hot-water taps

How much do Abode taps cost?

Abode doesn’t sell its taps directly, but through a distributor you can expect to pay around £749 for the Pronteau three-in-one or £1,375 for the Pronteau four-in-one.

The three-in-one tap provides hot and cold water as well as 98°C (near-boiling) water. The Pronteau four-in-one also dispenses filtered cold water. The three-in-one tap is available in five finishes: copper, nickel, graphite, chrome and black. The four-in-one only has two finishes (chrome and nickel) but there are five different styles to choose from.

Tank sizes

Both taps come with a three-litre water tank. The Proboil3 water tank is the first of its kind, according to Abode, which says that this intelligent boiler can take care of its long-term health by running self-diagnostics and alerting you ‘politely’ when it needs a new filter or descaling.

The filter in the three-in-one tap needs replacing every six to 12 months, and a twin pack will set you back £80. The timings are the same if you have the four-in-one tap, but one replacement filter will set you back £99.

CDA hot water taps

How much do CDA taps cost?

The TH101BR is a three-in-one tap that handles your hot, cold and boiling water. It’s CDA’s only hot water tap and it costs around £530 without installation.

There’s not much in the way of options with CDA’s tap – it’s available with a chrome finish.

2.4 litres, with a digital display that lets you adjust the temperature up to 98°C.

The filter needs to be replaced every six months, or your warranty may be invalidated. A replacement will set you back £37.50.

Zip hot water taps

How much do Zip hot water taps cost?

Prices start at £1,099 and go up to more than £3,000 for an all-in-one model.

You can choose from different styles of tap, and there are four options if you’re after a tap that dispenses hot water. Zip’s boiling water taps come with boiling water only, boiling water plus ‘ambient’ water, boiling and chilled, then an all-in-one tap that delivers boiling, chilled and sparkling water. All the taps filter water before it reaches your glass.

Tank size

The taps come with a standard tank size of 3 litres.

Replacement limescale filters cost £99, or £199 for a micron filter for the HydroTap G4. Zip recommends replacing the filter annually, though this depends on how often you use it. Zip also advises an annual ‘system sanitisation’ to maintain performance.

You can also sign up to the HydroCare plan (starting from £37 per month) for ongoing maintenance and support.

How to maintain your hot-water tap

All hot water taps have a filter to remove chemicals from the water. This will make the water taste better – useful if you have a three-in-one tap that delivers cold as well as hot water – and protects the tank from limescale and sediment, which can damage it.

Most manufacturers recommend that you change the filter every six to 12 months and, in some cases, it can invalidate your warranty if you don’t. Some manufacturers also recommend using a descaling solution to clean the inside of the tank.

The tap itself can be cleaned like any other, paying particular attention to limescale around the nozzle.

Is a boiling water tap dangerous in a kitchen?

You might worry about someone being scalded, especially if you have young children around. But the taps all have very effective safety mechanisms to avoid accidents. The Quooker, for example, has a childproof handle that has to be pushed in before it will turn; the spout is insulated so it doesn’t get too hot to the touch. Other taps have various safety-lock functions. And the water is released in an aerated spray that’s less likely to burn.

Above: The Quooker Modern Chrome Boiling Water Tap is available in the US via Amazon for $2,030 and comes with a tank. Many more styles and options are available via Quooker.

Does a boiling water tap need special plumbing or wiring?

Since you’re installing it in a sink, you already have hot and cold water lines in place. And if you have a dishwasher or garbage disposal unit nearby, the necessary electrical outlet is probably there as well. But while most manufacturers say that DIY installation is fairly easy, buyers—unless they’re handy—generally opt for professional installation.

Above: Hot water dispensers are also available in smaller profiles, not full faucets, like the InSinkErator Involve H-Wave Instant Hot Water Dispenser ($382.44 on Amazon), which has a thermostat that lets you adjust the water
temperature from 160°F to 210°F.

Does a boiling water tap have to be installed in its own sink?

No, it can go under your regular sink—as long as you have enough room there for the tank (tank size varies depending on the capacity; some are sold separately from the faucet). Otherwise, you could install the tap on a small bar sink, if your kitchen has one—assuming the tank will fit underneath.

It replaces your sink’s main faucet, and delivers fresh-tasting, filtered water that’s boiling, hot, or cold. See more of Franke’s offerings here.

What makes a better cup of tea: a kettle or a boiling water tap?

It’s hard to find consensus in the UK, where the perfect cup of tea is a fraught topic. Among the UK user comments on boiling water taps are complaints that “the water isn’t as hot as it is from the kettle, so your drinks don’t taste right” and “something’s missing from the ceremony of making a cup of tea.” But others in the sceptered isle insist “Plenty hot enough for tea!” and “wouldn’t be without it.” In general, American tea drinkers are probably less… finicky, and most will take quickly to the new gizmo.

How much do boiling water taps cost?

Prices in the US have dropped considerably since the first taps became available. Basic models start at around $140; others fall in the $250 to $400 range. The Quooker, however—the granddaddy of the boiling water tap—can set you back more than $2,000.

Is a boiling water tap worth the money?

That depends on how much you value convenience, saving time, and the ability to impress your friends and relatives. Apparently, even those who are skeptical at the outset soon can’t conceive of life without their boiling water tap. But before you buy, read up on consumer reviews and user comments. Boiling water taps may be life-changing, but some brands may need frequent repairs.

Most of us start our mornings with a fresh, hot cup of coffee or tea to warm our bodies after getting out of bed. When we drink water, we tend to prefer it cold, but according to Ayurvedic medicine, we have it all wrong. Regularly drinking very warm water, especially in the morning, can heal our bodies, providing digestive power and reducing metabolic waste that could have built up in our immune system.

“Physicians recommend drinking warm water in the morning, usually, with a polyphenol-rich lemon immersion, or with a tea shown to decrease free radical activity in the body,” Stella Metsovas, clinical nutritionist and media health expert in Food and Nutrition Sciences, told Medical Daily. The consumption of warm water increases the tightening of the intestines, which optimizes elimination. Unlike hot water, processed cold water is devoid of many essential minerals that could become very unfavorable to the digestive tract when consuming a meal. For cold water drinkers, Metsovas recommends refraining from drinking 20 minutes before eating — even if the source is natural spring water.

While drinking warm water may not suit your taste buds, it may be beneficial to put the caffeine and tea aside for your health’s sake. Here are six reasons why:

Drinking a cup of warm water in the morning can heal your body by aiding digestion and preventing premature aging. Photo courtesy of

1. Cleanses Digestion

A very warm cup of water in the morning can help cleanse your body by flushing out toxins. Water and other liquids help break down the food in your stomach and keep the digestive system on track. Warm water will help break down these foods even faster, making them easier for you to digest. Drinking cold water during or after a meal can actually harden the oil in consumed foods and therefore create a fat deposit in the intestine. Adding ice to processed cold water will strip it of natural-containing minerals, says Metsovas, as these minerals are essential to keeping the digestive tract healthy. Luckily, you can replace a glass of cold water with a warm one to aid digestion, especially after eating a meal.

2. Aids Constipation

At one point or another, many of us are plagued by this common stomach problem where we have little to no bowel movement. The strain felt during elimination, accompanied by bloating, is brought on by a lack of water in the body. Drinking very warm water in the morning on an empty stomach can help improve bowel movements and aid constipation while breaking down foods as they smoothly pass through the intestines. Stimulating the bowels will help return your body back to normal functioning.

3. Alleviates Pain

Warm water, considered to be nature’s most powerful home remedy, can help alleviate pain from menstruation to headaches. The heat from warm water is known to have a calming and soothing effect on the abdominal muscles, which can help provide instant relief for cramps and muscle spasms. According to Healthline, warm or hot water is usually better for cramps, as hot liquids increase blood flow to the skin and help relax the cramped muscles.

4. Sheds Excess Pounds

If you’re on a diet, chances are you’ve heard drinking a glass of warm water first thing in the morning can help with weight loss. Warm water increases body temperature, which therefore increases the metabolic rate. An increase in metabolic rate allows the body to burn more calories throughout the rate. It can also help the gastrointestinal tract and kidneys to function even better.

“Physicians recommend drinking warm water in the morning, usually, with a polyphenol-rich lemon immersion, or with a tea shown to decrease free radical activity in the body,” said Metsovas to Medical Daily. Drinking a glass of warm water and a lemon will help break down the adipose tissue, or body fat, in your body, and also control food craving due to lemon’s pectin fiber.

5. Improves Blood Circulation

The fat deposits in the body are eliminated along with accumulating deposits in the nervous system when you drink a glass of warm water. This flushes out the toxins that are circulating throughout the body and then enhances blood circulation. Making sure the muscles are relaxed will eliminate poor circulation and blood flow.

6. Halts Premature Aging

Premature aging is a woman’s worst nightmare, but luckily, this can be prevented by drinking warm water. The presence of toxins in the body can lead to aging faster, but warm water can help cleanse the body from those toxins, while repairing skin cells to increase elasticity. Metsovas told Medical Daily: “Women will always benefit because they more hormones to contend with, making constipation more of an issue.”

To reap the health benefits of warm water, drink it every morning plain or with a lemon for taste. Metsovas urges drinkers to have warm water, as drinking straight hot water can potentially be damaging to tissue in the mouth and esophagus. After boiling water, be sure to let it cool for a few minutes before you start consuming. Also, “always check with your prescribing physician before drinking warm water if you’re on any medications that could impact the efficacy of your medications,” Metsovas said.

Are You Drinking Enough Water?

Drinking Too Much Water Can Be Deadly

Ditch that cup of coffee. Hot water may be the ultimate health drink for you

Drinking hot water may be a traditional practice in India. But now several global researchers also agree that just consuming hot water (and not mixing lemon with it) would not only help you shed extra belly fat but also keep various health issues at bay. It has further been suggested that the optimum temperature of the hot water should be 120 degrees to avoid damaging the cells and inner skin layers in the mouth.

According to media reports, there are seven ways in which drinking hot water could work wonder for our bodies:

* Helps in weight loss

This is surely the most-wanted health benefit for fitness lovers who tirelessly hit the gym and follow a strict diet. Just by drinking a glass of water on an empty stomach can help you get rid of toxins and feel fuller for a longer time, thus preventing unnecessary snacking.

* Clears sinuses

Tired of a chronic ailment like sinus, which has given you constant headaches and a stuffy nose? Guess what, just a glass of warm water could help alleviate some of the symptoms of a respiratory tract infection.

Warm water makes you feel fuller for a longer time, thus preventing unnecessary snacking and promoting weight loss. ( )

* Easier on the teeth

Your teeth will also remain healthy for a long time if you practice drinking hot water. But make sure that the temperature is optimum enough to not damage your gum and enamel.

* Better for digestion

Are you affected by constant constipation or irregular bowel movements? Again, hot water is the solution for it. Warm water has a vasodilator effect, which means it widens the blood vessels and stimulates the blood flow towards the intestine, aiding the digestive process. Further, the intake of warm water on an empty stomach speeds up bowel movements. It has a faster hydrating effect, so when it is followed by a meal, the temperature helps emulsify fats, making them more digestible.

* Wash out toxins

A glass of hot water raises the core body temperature, stimulating the sweating process which is required to push out toxic elements from our body. In case, you do not like drinking lemon-based preparations, try taking green tea which has similar benefits.

* Pain reliever

Replace the intake of painkillers with water, especially for stomach-related pains which are largely caused due to digestive issues. Sometimes, pain caused in other body parts is also a result of dehydration which causes muscle contractions. Replace the glass of cold water with a hot one and body pains will soon be cured.

* Eases constipation

Constipation has become a major health problem among the youth. This is largely caused due to imbalanced eating habits. If you start each day with a drink of warm water, on an empty stomach, you can improve your bowel movements and reduce likelihood of constipation.

Instant Hot Water Dispenser — How to Buy & Install

Expert guide to buying the best kitchen instant hot water dispenser, including recommendations of makes and a description of how they work.

For today’s fast-paced, dinner-in-an-hour kitchen, an instant hot water dispenser offers the epitome of convenience. An instant hot water dispenser accelerates all kinds of kitchen tasks, from preparing hot drinks, soups,and sauces to warming baby bottles. It even melts wax and purges berry stains from clothing. Instant hot water dispensers take the lag time and the hassle out of many chores that used to require boiling water on the stove.


A sink-top dispenser can deliver both piping hot and icy cold water.

How much does it cost to keep the hot water ready and waiting? The usage is a little more than 1/2 kilowatt hour per 24 hours, which, depending on your local electricity rates, equates to about 6 or 7 cents a day.

Hot water dispensers come in two main types:

• Built-in hot water dispensers with under-sink tanks and sink-top spouts

• Countertop electric kettles and dispensers. For more about these, please see Countertop Instant Hot Water Kettles & Appliances.

Built-in Instant Hot Water Dispensers

This type of instant hot water dispenser is a point-of-use water heater. It is a miniature electric water heater with storage tank inside the unit. The tank connects to a small sink-top spout that serves up the heated water. Many instant hot water dispensers also connect to a water filter. Or you can get a hot cold water dispenser that delivers both hot and cold water at the sink.

Features of Instant Water Dispensers

Products sold by different manufacturers vary only slightly. Inside the compact unit, all have an interior tank that holds water, and an electric heating element that heats the water. Types with a stainless steel interior tank will last longer than lower-priced models with a rubber bladder tank.

A control dial on the outside of the unit allows you to tweak the temperature or turn the unit off. Instant water dispensers have a thermostat that automatically shuts off the heating element when the water in the tank reaches the set temperature. For more about how they work, see How a Hot Water Dispenser Works, below.

If you’re going on vacation or you’ll be away from the house for more than a day or two, turn the control dial off so you don’t waste energy maintaining hot water in the unit.

The most common part to fail is the thermostat. If it goes out, fixing the problem is more hassle than it’s worth. You’re better off just replacing the water dispenser if or when this happens. Thanks to quick-connect couplings, you can usually change-out an instant hot water dispenser tank in less than an hour.

Water Dispenser Tank Size & Power

Tanks vary in size and by the heating elements’ wattage. Most are 1/3- or 1/2- gallon and range from 500 to 1,300 watts. A 750-watt, 1/2-gallon tank will produce up to 60 cups of hot water per hour. Higher wattage tanks can deliver up to 100 cups. Most makes have a dial for fine-tuning the temperature up to 190 degrees F, and must be plugged into a 120-volt electrical receptacle.


This top-rated instant hot water dispenser tank includes an inline filter.

Where to Buy Water Dispensers

Though units sold through specifiers such as designers, kitchen shops, and wholesale plumbing houses are generally installed by plumbers, those sold through home centers and hardware stores and online through sites such as Amazon.

A tank-style instant hot water dispenser is one of those items that you might as well buy online—appearance doesn’t really matter much because the tank sits hidden under the sink. In addition, online resources make comparing specifications easy. Furthermore, online prices tend to be significantly lower than retail store prices, and you can save a trip to the home center by having the small appliance delivered. On this page, you’ll find links to Amazon, where you’re likely to find some of the best prices.

Water Dispenser Buying Considerations

Given the similarity of products, when shopping for a new instant hot water dispenser, focus on price, availability, and warranty. Note that the price often does not include the sink-top spout. Spouts are discussed below.

Waste King

Popular makes available on Amazon include: Everpure, Waste King, and InSinkErator.

A best seller is the InSinkErator HWT-F1000S (shown above), which has a stainless steel tank and also a filter that connects to the faucet. Tank warranty is for 3 years.

Sink-Top Spouts for Water Dispensers

Because the sink-top spout is the only visible part of an instant water dispenser, manufactures offer many styles and finishes. Typical finishes include white, black, almond, chrome, satin nickel, and brass. In terms of style, you’ll find everything from low spouts with handles you twist to tall, gooseneck units that allow plenty of room for filling tall cups and kettles. As a result, chances are good that you can match the look of your sink fixtures.

Some units, such as KitchenAid’s and Whirlaway’s, have a twist grip that releases water with a quarter turn. In contrast, others, such as InSinkErator’s, have a lever release. Elkay’s spouts, which tout “no lead” construction, have a button on top. Franke makes the smartly styled Little Butler, which has a tall, L-shaped spout and a lever handle.

Hot and Cold Water Dispenser

Some manufacturers—Franke and InSinkErator to name two—offer models that dispense both hot and cold water through one faucet. The cold water side can be connected to a chiller or the refrigerator. Both supplies can also connect to a water treatment system. This type of faucet eliminates the need for yet another spout—the purified cold water spout—at the sink.

For sinks that don’t have the needed mounting hole for a new faucet, replacing a purifier spout with one of these is the perfect solution.

If you want instant hot water but you don’t want to mess with the plumbing, see Countertop Instant Hot Water Kettles & Appliances.

How an Instant Hot Water Heater Works

Instant hot water dispensers are simply miniature electric water heaters that serve a single faucet. A small, under-sink tank heats and holds nearly boiling water, ready for steamy delivery through a sink-top spout that’s separate from the main tap.

Unlike a conventional water heater, however, the tank never becomes pressurized. The system hooks up directly to a cold water pipe under the sink; incoming water travels through the body of the spout and into the tank, where it’s heated by an electric coil.

The heated water expands, filling an expansion chamber in the upper part of the tank. When the faucet is turned on, more cold water is released into the bottom of the storage tank, displacing hot water in the tank and expansion chamber and forcing the heated water up through the faucet.

The spout delivers water more slowly than a typical faucet does, and the water is much hotter than a standard hot water tap’s—about 190 degrees F. instead of 120 degrees. The heated water arrives immediately; you don’t have to wait for it to warm up.

An adjustable thermostat controls water temperature with most models. Adjustment is needed only if the water is too cool or if it’s so hot that it boils away, causing the tank to overheat. (To prevent damage, the tank should be protected from overheating by a replaceable thermal fuse.) Noteworthy: It’s a good idea to turn down the dial or unplug the unit when you go on vacation.

Tanks vary in size and by the heating elements’ wattage. Most are 1/3- or 1/2- gallon and range from 500 to 1,300 watts. A 750-watt, 1/2-gallon tank will produce up to 60 cups of hot water per hour. Higher wattage tanks can deliver up to 100 cups.

As with any water heater, hot water dispensers may accumulate scale in regions of the country that have hard water. Some units have drain plugs at the bottom to allow you to drain the tank once or twice a year.

How to Install a Hot-Water Dispenser

To install a hot water dispenser, the sink top must have a hole that can receive the spout. Most hot water dispensers are installed during kitchen remodeling in new sinks that have the proper number and configuration of holes needed.

Can Your Sink Receive One of These?

Though retrofits can be a little bit tricky, they’re not impossible. If your sink has a sprayer, you may be able to remove the sprayer and use the hole that it occupied. Or, if you have a separate spout for purified water, you can replace that one with a hot-and-cold model. Or, check to see if the sink has an extra hole that hasn’t been punched out yet.

In a real pinch, you can have a plumbing contractor drill a hole in stainless steel or porcelain, though you risk cracking porcelain. A much easier and more affordable solution is to buy a countertop appliance that essentially does the same thing without the need for plumbing. See Countertop Instant Hot Water Kettles & Appliances.

Hot Water Dispenser Installation

Installation instructions are always included with the appliance—and you should follow them explicitly. With most models:

1 Insert the dispenser spout through the sink hole and tighten it in place from underneath with a large nut. Be sure to pay attention to the instructions for proper placement of trim, washers, and seals.

Water dispenser fits into hole in sink rim.

2 Mount the tank onto the cabinet wall under the sink.

3 Connect the tank to the water supply pipe. To do this, clamp a “saddle valve” onto the cold water pipe under the sink to tap into the water supply, and then connect the appliance to this valve with 1/4-inch copper tubing, using compression fittings.

4 Connect the spout to the tank. The spout often has two plastic tubes—red for hot and blue for cold—that deliver water from the tank. Simply plug these into connectors in the top of the tank unit.

©Don Vandervort, HomeTips

Plastic tubing simply plugs into the small electric heating unit under the sink.

5 Most appliances have a three-pronged plug that you just plug into a grounded, 15-amp receptacle (in some cases, they may share the receptacle used by a garbage disposal, but be sure to follow the manufacturer’s directions and adhere to local building codes).

This video shows how to install a water dispenser. Though it is specific to InSinkErator, one of the popular brands, techniques are similar to most brands.
