10 Best Instant Hot Water Taps

Instant hot water taps are a bit of a kitchen revelation. Forget waiting for kettles to boil or refilling your boiling water dispenser – instant hot water taps give you immediate perfect-temperature water for when that coffee or tea drink craving hits.

The taps we have listed below are all perfect for making hot drinks. This is because they don’t actually reach boiling point, have the option to finely tune the temperature output or the ability to quickly switch to cold water to bring it down a degree or two. 

Despite what you may assume, the ideal temperature for brewing coffee and tea is just under boiling point, so some other boiling water taps will be too extreme for hot drinks.

We have selected some of the best instant hot water taps available to buy online to make your brewtime seamless.

The Best Instant Hot Water Kitchen Taps

1.
Bristan GLL RAPSNK4 C

Specifications

  • Temperature: 4 Settings – 80, 86, 92, 98°C
  • Dimensions: Tank 31.5 x 22.5 x 20cm
  • Tank Capacity: 3L

By far one of the best instant hot water taps around, because it does everything that a special tap such as this can do.

Not only are there four temperature settings to choose from depending on what you’re up to, but the 4-in-1 means it can filter your cold drinking water for immediate dilute juice, and produce ordinary hot and cold water too so you can replace your existing kitchen tap.

The temperatures it can reach are 80°C, 86°C, 92°C and 98°C, so with a little dash of cold water on the top temperature, you can get the perfect temperature. The lower levels are great for green or fruit teas, and the boiling water can only be operated by holding the sensor continuously so there will be no accidental scalds.

It holds three litres of water at once, so is great for preparing around eight large cups at once. With one of the smallest tanks on the market, it is great for pretty much any undersink setup too.

Reasons to Buy

  • Choice of temperatures
  • Great value for a 4-in-1

Reasons to Avoid

  • Price of filters is a little high

2.
Bristan GLL RAPSNK3 C

Specifications

  • Temperature: 7 Settings – Between 75°C to 98°C
  • Dimensions: Tank 33 x 17.5 x 36.5 cm
  • Tank Capacity: 2.4L

This RAPSNK3 is similar to the Bristan RAPSNK4, except it doesn’t filter the water. After all, not everyone will need this feature, and if it is just instant hot water you’re after, it saves you quite a bit of money in comparison.

The tap is of a similar design, curved and with a chrome finish, with a small tank so it will fit in pretty much any space. The tank holds 2.4 litres of water at any one time, roughly enough for about six mugs of coffee.

Another big difference is the choice of temperature selection, with the option to pick between 75°C and 98°C for not only the perfect cuppa, but also the option for some personalisation in case you like yours a bit cooler or hotter than norm.

Reasons to Buy

  • Wide choice of temperatures
  • Easy to access hot water

Reasons to Avoid

  • Boiler is on the bulkier side

3.
Redring REDITAP 3-in-1

Specifications

  • Temperature: 65-100°C
  • Dimensions: Tank 58.5 x 37.5 x 32.5 cm
  • Tank Capacity: 2L

Able to give you ordinary warm and cold water as well as instant hot water, this is a great tap to install in your kitchen and really looks the part too.

It can reach between 65-100°C, which is a great medium level for hot drinks. Taking just 12 minutes to heat the full tank from cold, you have a pretty much constant supply of water ready to make drinks, boil pasta and wash greasy pans.

Thermal overheat protection will ensure that the water is never hotter than you’ve set it, so there will be no surprises or accidents. It is a competitive price, and is one of the easiest to descale.

Reasons to Buy

  • Can heat up to 33 cups per hour
  • Wide temperature range

Reasons to Avoid

  • Water boiler is noisy when at work

4.
Insinkerator 3N1

Specifications

  • Temperature: 88 ̊C to 98 ̊C
  • Dimensions: Tank 15.7 x 20.6 x 31cm
  • Tank Capacity: 2.5L

One of the biggest brands in the kitchen water tap world, Insinkerator are pros at making high-quality trusted products.

The 3N1 can replace your current tap without needing a separate ordinary mains tap. With a 2.5L tank, you can dispense up to 100 cups of water per hour, so it is perfect for high-demand commercial environments too.

It is factory set at 96 ̊C, ready for hot drinks fans to get started straight away, but can be altered between 88 ̊C and 98 ̊C if you’re using it for other things too.

To access the boiling water, you need to push down the lever first and keep it depressed for continuous running, so it is safe and the tap itself doesn’t get too hot to touch.

Reasons to Buy

  • Perfect temperature for hot drinks
  • Easy to access hot water

Reasons to Avoid

  • Needs 1.8 bars to work – may be unsuitable for low pressure homes

5.
Hyco Zen Solo

Specifications

  • Temperature: 98°C to 100°C
  • Dimensions: Tap 4.9 x 15.2 x 28.8 cm
  • Tank Capacity: 3L

Not the most famous manufacturer on our list, but it comes in at a great price for the tank capacity, style and specs.

It is a true 100°C boiling water tap, which is too hot for drinks, but you do have the option to reduce this down to 98°C. This makes it a great tap if you want something which can wash pans just as well as making your morning coffee.

One of the few which has a full 360°C swivel function, this Zen Solo is also great if you want something versatile in positioning, over a large Belfast sink or double sinh setup on a kitchen island for example.

It is cool to touch at all times, and only costs around 4p per day to run which is brilliant if your boiling water is always in demand but you’re concerned about your energy-sapping kettle.

Reasons to Buy

  • One of the most stylish
  • LED status ring on base to indicate ready or heating (green/red)

Reasons to Avoid

  • Doesn’t go below 98 degrees

6.
InSinkErator 44317 GN1100C

Specifications

  • Temperature: 98°C
  • Dimensions: Tap 14 x 4.2 x 21.3 cm
  • Tank Capacity: 2.5L

Want to keep your ordinary mains water tap and instead install a dedicated boiling water tap? This Insinkerator is a great solution, and there is an adjustable temperature option so it is flexible too.

It can reach a maximum of 98°C, and is able to produce around 100 cups every hour. You can mount it either onto the kitchen sink or straight onto your bench depending on the setup and layout of your kitchen.

One of the benefits of keeping the hot water tap separately is that they are generally a bit cheaper, but just make sure you have enough room for installation first.

Reasons to Buy

  • Scale reduction technology to protect workings
  • Touch control tank is easy to use

Reasons to Avoid

  • Boiler and filter are bulky

7.
GROHE 30058001

Specifications

  • Temperature: 99°C
  • Dimensions: Tank 59.5 x 40 x 40cm
  • Tank Capacity: 4L

One of the priciest on the list, but you do get one of the largest tanks and a real quality finish.

Grohe is a big name in the tap industry, and this is a great solution if you want a model which does everything. The right hand side lever accesses ordinary mains water, and there is a child lock in place for the boiling water to minimise the risk of accidents. Just hold the button down for three seconds to disable the lock, and hold down the pour button for as long as you need the water to pour.

It is available as a C-Spout or L-Spout design, so you can get the finish and look you wish for.

Reasons to Buy

  • Available in two styles
  • Good child lock

Reasons to Avoid

  • One of the pricier options

8.
Insinkerator 3573

Specifications

  • Temperature: 98°C
  • Dimensions: Tank 52.1 x 35.8 x 29.7 cm

Insinkerator is a name which features frequently on these lists. This complete kit, including tank, filter and tap, is great value for the quality.

It is a hot water-only tap, so will have to be installed alongside your existing mains tap. This could be the perfect setup if you’re concerned about safety, though. It is also fully insulated, so cool to touch no matter the temperature of the water.

Up to 60 cups of water can be poured per hour, and it has a super-fast reheat time which is great if it is going to be in demand. There is protection to ensure it doesn’t overboil too, so you’re never going to suffer from a below-par cuppa.

Although it is a tad too hot for the optimum coffee temperature, adding a splash of cold water will resolve this if you find it is impairing the taste.

Reasons to Buy

  • Easy to install

Reasons to Avoid

  • Takes a little while to fill up and reheat if completely emptied

9.
Franke 1190380520 Omni

It gives true 100°C water. While this is a little too hot for drinks technically, if you’re using it as a boiling water tap for making pasta/washing dishes/sterilising baby bottles first and a drinks maker second, it is easy to live with.

Reasons to Buy

  • Stylish
  • Good level of secure access to water

Reasons to Avoid

  • Price

10.

As it is 4-in-1, it can replace your current tap, and will do pretty much all of the jobs you require water for.

This Qettle can only dispense water at 100°C, which is why it isn’t higher up on our list of the best hot water taps for coffee making, but if we are talking generally then it would definitely make the top 3.

Reasons to Buy

Instant Hot Water Tap Buying Guide

The Best Water Temperature For Coffee

As mentioned in the introduction, 100°C is actually too hot for most coffees and teas. It results in burnt grounds or leaves, resulting in a slightly bitter taste.

The ideal temperature for brewing coffee is between 91°C (195 F) and 96°C (205 F). The closer to the top level the better, and anything below 91°C will not extract the flavours efficiently.

Some of the taps above are boiling taps, so won’t go much below 100°C and are therefore not the absolute best for hot drink production, but they are better for anyone who also needs boiling water for other household tasks. Adding a dash of cold water to the cup before adding the coffee is a good way of getting around this.

Reasons To Buy

  • Quick – They really are instant, which saves time waiting for water to heat otherwise
  • Energy Efficient – They’re thought to be cheaper to run than boiling a kettle. There is also no wasted water, as you just use what you need – no boiling excess water and pouring it away unused
  • Multiple Uses – We love them for making hot drinks (obviously), but they can also be good when cleaning, making pasta, boiling vegetables, filling hot water bottles or sterilising
  • More Space – There is no need for a kettle taking up space

Types Of Instant Hot Water Tap

  • Single Function – These only produce hot water, so sit alongside your mains tap
  • 3-in-1 – Usually provide you with ordinary hot and cold mains water as well as the boiling water
  • 4-in-1 – As the 3-in-1, but also providing filtered cold water which is great for dilute drinks 

Things To Bear In Mind

  • Tank Size – This is how much hot water the tank can hold at any one time. If you have a large family of hot drink lovers or always have a lot of washing up to do, look for one which is on the larger side, around 3 or 4 litres
  • Dimensions – The size of the tank is probably the most important factor here. You want to ensure it will fit under your sink in the cupboard. Also look at the size of the tap though, so it isn’t too imposing or small, as well as the size of the neck
  • Water Reheat Time – Most tanks will take around 10-15 minutes to properly refill and get the water back up to temperature, but it could be worth bearing in mind if it will be in demand or you’re in a commercial environment
  • Safety Features – Most boiling water taps will have a two-step method to access the hot water but think about how secure you want it to be. If there are children around, you may want top security. If not and you’re confident there is little chance of accidents, you may want something easier
  • Tap Shape and Style – Not only do you need to bear in mind the dimensions of the tap, but also how it will look and the materials/finish used
  • Filters – If your tap is a 4-in-1 with filtered drinking water, check the cost of the filter and availability to ensure it won’t cost too much to run in the long-term
  • Fitting Cost – Most will require professional fitting as there is also electricity involved. Factor in this cost if you have set a budget
