QETTLE Boiler Tanks
A QETTLE boiling water tap can be teamed with a 2, 4 or 7 litre boiler tank. So, from taking care of a single cuppa to keeping the whole office in tea and coffee, there's a tank that will tick the box. Making instant hot drinks is just the beginning with a QETTLE, so think about how you'll use your tap before you choose its tank size.
A 2L tank will give you 4 cups of boiling water in one go, a 4L tank delivers 8 cups and a 7L tank provides 14 cups.
What size do you need?
What tank size you choose will depend on how you and your family would like to use your QETTLE. Will it just be for quick cuppas – or more? QETTLE boiler tanks are designed to be compact, but it’s also worth checking out undersink space. Watch our video on undersink space here.

Do boiling water taps save money?
Boiling water taps are highly energy efficient. In fact, a boiling water tap is probably easier on your pocket than a kettle. In standby mode, a QETTLE boiling water tap consumer just 0.8 watts of electricity per hour. Based on an average tariff of 14 pence/kWh, this amounts to a QETTLE costing just 3 pence to run, a day. So, making the equivalent of 10, 300ml mugs of tea a day could cost as little as 10 pence in total.
This is in comparison to a kettle, which will cost an average of 2.5 pence every time it is boiled. And the cost-savings don’t stop with boiling water. Choose a QETTLE Original 4 in 1, and you’ll be getting filtered drinking water on tap, too. So, buying expensive bottled water will become a thing of the past.
How much is a boiling water tap?
At around just over £500.00 for a complete QETTLE boiling water tap, QETTLE is much more affordable than other 100°C boiling water taps. However, our secret is the ingenious, fully patented tech inside a QETTLE tap. Unlike other boiling water taps, QETTLE does not use expensive, electronic parts. Instead, it uses an award-winning, British-designed mechanical internal system which significantly reduces its cost. Maintenance is simple and inexpensive, and no specialist servicing is required. We have been innovating multi-functional kitchen taps for over 50 years, and we are justly proud of QETTLE’s clever design, performance and affordability. Why not spread the cost of your QETTLE by opting for our new, easy payments with 0% interest?
Are boiling water taps safe?
A QETTLE boiling water tap could be considered as much safer than a kettle. Not only do QETTLE boiling water taps feature two-stage safety and a cool-touch spout, but, unlike a kettle, they are fixed in one place, cannot be pulled by a cable, and cannot topple over, spilling dangerous volumes of boiling water. All QETTLE taps come with a safety clip. When in place, the clip makes it impossible for boiling water to be dispensed. But even with the clip removed, it is still necessary for the tap’s handle lock to be deactivated before boiling water can be accessed. A small button on the tap’s handle must be pressed down at the same time as the handle is turned clockwise. Only then can boiling water be dispensed.
