how do boiling water taps work

Boiling water taps are connected to a small tank, usually installed under the kitchen sink in a cabinet. This tank is connected to your water supply and heats the water to around-boiling temperatures, typically between 95-108°C – depending on the make and model.

The system uses an electric element to heat the water, similar to how an electric kettle works, but with a much larger capacity. It’s kind of like a big heated thermos flask.

When you activate the tap, it draws water from this tank, delivering boiling water instantly. The tank continuously heats and replenishes its supply, ensuring a constant availability of hot water.

If you empty the entire tank in quick succession, you may need to wait a few minutes for it to fill back up and get up to temperature again.

Generally, the average cost of a boiling water tap in the UK is around £1400.

However, it can range from about £545 to £3,600. This range includes various models that offer different features, capabilities and finishes.

As a quick guide, I’ve put together a price range for some of the most popular boiling water taps to give you an idea.

You will also need to factor in any other accessories you might want, such as Quooker’s Scale Control, which is great if you live in a hard water area.

As well as any replacement filters, cartridges and CO2 cylinders you will need as you use your tap over the years. For Quooker taps, these can range from £50-90 each.

Understanding the Cost of Installing a Boiling Water Tap

When you decide to install a boiling water tap, it’s important to consider the additional cost of installation.

The installation area must be equipped with specific services:

  • a 13 amp power socket is essential, and if you’re installing a Quooker CUBE, you’ll need two of these sockets.
  • a waste system and both hot and cold water supplies must be within 50 cm of the installation spot, below the worktop height, and fully accessible.
  • Plus, don’t forget to account for the space required for the tank and any additional accessories.

Hiring a plumber for the installation is a significant part of the cost, which can easily amount to £150+ for a call-out and fix.

Quooker also offers an installation service, which is typically priced between £99 and £150. Occasionally, I’ve seen them run promotions where the installation might be offered for free.

However, you still need to ensure that all the necessary preparations, like power sockets and water supply, are in place and ready for installation.

Pros Of Boiling Water Taps

  1. Instant Access to Boiling Water: Eliminates waiting time for water to boil, perfect for quick hot drinks or speeding up cooking processes.

  2. Energy Efficiency: More energy-efficient than repeatedly boiling a kettle, especially if you frequently need hot water.

  3. Space-saving: Reduces clutter on the countertop by eliminating the need for a kettle.

  4. Improved Safety: Often comes with safety features to prevent accidental scalding, safer than a kettle which can be split.

  5. Enhanced Kitchen Aesthetics: Sleek and modern designs of boiling water taps can enhance the overall look of your kitchen.

  6. Convenience for Cooking: Instant boiling water is handy for cooking tasks like blanching vegetables or starting pasta.

  7. Better Water Quality: Many models include filtration systems, providing cleaner and better-tasting water compared to tap water.

  8. Reduces Plastic Waste: If combined with a sparkling water function, it can reduce the need for buying plastic bottled water.

Cons Of Boiling Water Taps

  1. High Initial Cost: Boiling water taps can be expensive to purchase, with high-end models costing significantly more than standard taps or kettles. Seriously, that’s a lot of kettles you could buy for the same amount!

  2. Installation Costs: Professional installation is required, which adds to the overall expense. This includes the cost of a plumber and potential adjustments to plumbing or electrical setups.

  3. Requires Regular Maintenance: To ensure proper functioning and water quality, these taps often require regular maintenance, including filter changes.

  4. Space Requirements Under the Sink: The tank and filtration system require space under the sink, which could be an issue in smaller kitchens with limited under-sink space.

  5. Complexity in Repair: If issues arise, boiling water taps can be more complex and costly to repair compared to traditional taps or kettles.

  6. Safety Concerns: Despite safety features, there’s still a risk of scalding, especially in households with children or elderly individuals.

  7. Dependence on Electricity: These taps rely on electricity to heat water, so in the event of a power outage, you won’t have access to boiling water.

Are Boiling Water Taps Worth It?

If your budget allows, I would definitely recommend getting a boiling water tap.

From my experience, clients who have opted for a boiling water tap have never looked back. They find it incredibly useful and a great addition to their kitchen.

However, it’s important to remember that opting for a boiling water tap is more of a lifestyle choice than a financial one.

Yes, they are expensive, and as I said before, you can buy a lot of kettles for the price of one boiling water tap.

But what you’re investing in is not just a kitchen appliance; it’s the convenience, the aesthetic appeal, and the time-saving aspects that come with it.

So, if quick and easy access to boiling water, a sleek kitchen look, and saving time are priorities for you, and if your budget can accommodate it, I believe a boiling water tap is a worthwhile investment.

It’s all about weighing the pros and cons and deciding what fits best with your lifestyle and kitchen needs.


Are Boiling Water Taps Safe?

Yes, boiling water taps are safe.

Boiling water taps come equipped with various built-in safety features.

For instance, Quooker taps require a double push-and-twist action to operate, which is a deliberate mechanism to ensure that boiling water isn’t released unintentionally.

Also, a Quooker tap water flow is made of fine drops, not a solid stream. This is much less dangerous compared to a solid jet of water from an overturned kettle, which could cause severe burns instantly.

As well as these, you can’t knock over a tap.

How long should a boiling water tap last?

Generally, you can expect a high-quality boiling water tap to last between 10 to 15 years, although I’ve no doubt some can last even longer with proper care.

Key factors that influence the longevity of a boiling water tap include:

  1. Quality of the Product: Premium brands often use higher quality materials and construction, which can extend the tap’s lifespan.
  2. Frequency of Use: Regular use can lead to wear and tear over time. However, boiling water taps are designed to withstand frequent use.
  3. Maintenance: Regular maintenance, such as changing filters, is crucial for prolonging the life of the tap.
  4. Water Quality: The type of water in your area (hard or soft) can impact the tap. Hard water areas might require more frequent filter changes to prevent buildup that could shorten the tap’s life.
  5. Installation: Proper installation by a qualified professional is essential to ensure that the tap functions correctly and lasts as long as possible.
