Boiling Water Taps: How Do They Work?
A boiling water tap does what it says on the tin. These high tech taps can produce boiling water (or near-boiling water) at the turn of a tap. No waiting for a kettle, just instant boiling water. This may seem like a trivial addition to the kitchen but when you consider, on average, people spend 3 minutes a day waiting for a kettle. This makes up 18 hours a year.
Not to mention how much these taps reduce your carbon footprint. A boiling water tap is more than just a luxury, it’s an investment that saves you time, makes life more convenient and reduces your power usage.
What are boiling water taps?
Available in various formats, either as a stand-alone tap or as part of a 3-in-1 (boiling, hot and cold) or 4-in-1 (boiling, hot, cold and filtered) tap, boiling water taps are designed with safety and style in mind.
Quooker is the pioneer of this technology and currently boasts a patent on the only true boiling-point water tap. Their water taps regularly reach the 100°C while competitors can only reach 98°C. There is, however, little difference between the two temperatures with tea and coffee having recommended water temperatures of 80°C to 90°C depending on the type.
Safety is one of the most important facets of these taps. When you have a tap that can produce water between 98°C-100°C it’s important to protect your children and yourself from burns. Most instant hot water taps use a safety sprung handle. This means that once you release the handle it will automatically spring back to an off position. This means you can’t accidentally leave the boiling water tap running.
Safety is two-fold with taps requiring you to hold down a safety button while opening the tap. If you don’t hold down the safety switch while opening the tap, it will only run cold water.
How do they work?
Boiling water tap systems work in various ways with the two most common being a pressurised system and a vented system. Quooker, Zip and Grohe Red use a pressurised system. This system stores the water at a higher temperature and delivers it a higher temperature. This means water is hotter for quicker and won’t cool as you fill your cup. Pressurised systems can be slower to reheat and usually have smaller tanks than vented systems.
Insinkerator, Vellamo Mokka and Cappa are famous for their use of vented systems. Using a non-pressurised open vented tank is considered to be safer. They are also easier to install and easier to service with quicker reheat times. The water is stored at a slightly lower temperature to that in a pressurised system, meaning it can’t reach a true 100°C.
The drawbacks of a vented system are less effective temperature control and a more basic tank functionality. This is often seen through running the tap for an extended period. The temperature can drop quickly as the reservoir empties and water aerates the flow.
What are the pros and cons?
Boiling water taps have a lot of benefits. They are convenient, efficient and made to a high standard. They can save you time and energy, especially if you’re a tea or coffee drinker. They also work great in smaller kitchens where you need to save counter space.
While there are a lot of positives it’s worth remembering that these taps come with a few extra tanks, filters and wires. In 99% of cases, it’s a simple job for your plumber to do and won’t cost that much more than installing a regular tap.
Many people are reluctant to buy a boiling water tap because they’re worried about the costs. Convenience, style and safety are difficult to put a price on and this investment is one that will grow on you until you’ll never think of a kitchen without one.
