What are the 5 best boiling water taps for every budget in 2025? (with reviews)
Is your kettle slow, noisy, and slowly becoming overcome with limescale? Boiling water taps offer a faster, more efficient way to enjoy hot drinks, while also helping you reduce water and energy use. For maximum performance and convenience, it’s worth choosing the best boiling water tap available.
While the initial cost of a boiling water tap is high compared to your standard kettle, this is a small price to pay for convenience, safety, lower running costs, and higher-quality tap water in many cases. Opting for the best hot water tap can further enhance energy efficiency and kitchen functionality.
We’re here to inspect the top five boiling water taps in the market, and help you decide which is best for your kitchen. A few key considerations are:
Safety – Since boiling water taps dispense near-instant boiling water, safety features are essential. Without the right protections in place, there’s a higher risk of accidental burns. Look for models with safety buttons, childproof handles, or insulated spouts to help prevent injuries.
Tank Capacity – Smaller boiling water taps typically come with 2–3 litre tanks, which are usually sufficient for everyday use in a small household. Larger tanks (up to 10+ litres) are available if you need more capacity, but keep in mind they’ll take up more space under your sink.
Flexible hoses – A pull-out extendable hose is best if you’re looking to use the best instant hot water tap for cooking, as it’s easier to fill up large saucepans and pots that wouldn’t otherwise fit under the sink.
Pricing – Most high-quality taps start at £500, which typically includes a basic stainless finish and a small tank. More expensive options may also include water filtration or sparkling water functions to expand your range of tap water choices.
Upgrades and improvements – A tap that combines with other systems or a multi-functional tap, like a Reverse Osmosis machine or water softener, gives you the opportunity to enjoy the highest-quality water while prolonging the lifespan of your appliances.

The pros and cons of boiling water taps
Boiling water taps are useful, but the high initial costs mean it’s important to understand the pros and cons before you invest in one.
Pros of an instant boiling water tap
- You can save water — and money on your water bills. Filling your mug or saucepan directly from the tap means you won’t overfill your kettle and boil more water than you need. The best boiling water tap ensures that you’re only boiling the exact amount of water needed, making it highly efficient.
- You’ll lower your energy consumption — boiling water taps use almost half the energy of boiling a kettle. When you consider that you use your kettle multiple times a day but have your tap on standby all day, the cost can add up. The best hot water taps help to minimise this energy waste.
- It’s convenient compared to traditional kettles — when working with boiling water, the less heavy lifting the better. Having a special tap for it means no more struggling to lift full kettles, and it’s easier to fill the exact container you need, whether that’s a mug for tea or a saucepan for soups and stews. If you’re looking for the best instant hot water tap, this is definitely the way to go.
- It can be safer than traditional kettles — the majority of boiling water taps include safety features for both children and adults, which is a contrast to kettles, where the main safety feature is to be out of reach of children. It can also be riskier to use a kettle to fill a saucepan or mug, as the flow of water means it’s more likely to splash or spill than boiling water direct from a tap.
Cons of owning an instant boiling water tap
- Limescale build-up — again, like regular taps, living in a hard water area can have a negative impact on your boiling water faucet. Limescale can move in and lower the efficiency and lifetime of your boiling water system unless you also invest in a water softener in connection with it.
- You’ll need cupboard space — while a boiling water tap can save you countertop space, the boiler/tank below your sink can take up a bit of cupboard space, especially if you’re investing in a larger tank.
- Maintenance is ongoing — you’ll need to keep your tap clean and in order, which can also involve filter changes every 6-12 months depending on the tap you choose. And, just like a normal tap, there can be issues like leaks or no water coming out of your tap. In these cases it’s best to call in a professional plumber to take a look.
How do boiling water taps work?
Boiling water taps are easily integrated into your kitchen setup, just like a regular tap. However, unlike a regular tap, they connect to a mini boiler tank that keeps the water hot, so you can access that boiling water on demand. Depending on the tap you choose, you may be able to adjust the heat within this tank as well.
Most varieties supply boiling, hot and cold water, with many offering options for chilled or sparkling water either as part of a 5-in-1 tap or as optional add-ons for an extra fee.
Safety features are a top priority for most manufacturers, with many models sporting insulated spouts that are cool to the touch, automatic shut-off features and child-safe handles or buttons, that minimise any chance of injury.
Are boiling water taps worth it?
If you’re looking to save counter space and spend less time in the kitchen when making tea and soups, a boiling water tap is worth the investment.
The Culligan Milano Furnas offers all the above benefits, as well as energy-efficiency and a filter to upgrade the quality of your water even when you aren’t using the boiling function. Explore our full range of boiling water faucets today.
