Delivering up to eight cups of boiling water at one time, this intelligently named boiling water tap 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.

Specifications
Reasons to buy
Reasons to avoid
This three-in-one (cold, hot and near-boiling) tap from 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. Insinkerator Filtered Cold and Boiling Water Tap
Best single-lever hot water tap: with a small tank and a streamlined design, this is our best for bijou kitchens
Specifications
Reasons to buy
Reasons to avoid
This filtered water tap from Insinkerator 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.
6. Franke Omni 4-in-1 boiling water tap
Best boiling water tap for families: Franke’s foolproof offering is great for family homes
Specifications
Reasons to buy
Reasons to avoid
Aptly named, this boiling water tap from Franke 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.
7. 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
Specifications
Reasons to buy
Reasons to avoid

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.

Specifications

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.

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
Where to buy the best boiling water tap
So you've honed in on the best boiling water tap or hot water tap for the household, but there a few things now to consider on how to actually get it into the home.
Installation
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.
Filters
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.
