Frequently Asked Questions

Does the water come out at a true 100°C?

Most systems dispense water at 98°C to 99°C. This is intentional; 98°C is considered the "perfect" temperature for tea and coffee, as 100°C boiling water can actually "scald" the tea leaves or coffee grounds, resulting in a bitter taste. The slight drop from the tank to the spout also prevents "spitting" and ensures a smooth, steady flow.

How much space does the boiling water tank take up?

Most of our boiler tanks are designed to be compact, typically measuring around 20cm x 20cm x 40cm. They fit comfortably at the back or side of a standard 600mm sink base cabinet, leaving plenty of room for your typical under-sink storage or pull-out bins. You will also need a standard 13-amp power socket within reach of the tank's cable. We also have a corner mounted space saving tank available soon.

Can I replace my existing kitchen tap with a 3-in-1 system?

Yes, it uses a standard 35mm hole

How often do the filters need changing?

To protect the boiler tank from limescale build-up and ensure your water tastes fresh, filters typically need replacing every 6 to 12 months, depending on your water usage and local water hardness. Most systems feature a "filter change" indicator light to remind you. Regular filter changes are essential to maintain your manufacturer's warranty. You can find a full range of replacement filters on our website.

Do I need a specialist plumber to install a boiling water tap?

Most 3-in-1 or 4-in-1 systems are designed for standard UK plumbing. You will need a standard 35mm tap hole, a 13amp power socket under the sink for the boiler tank, and a cold water connection. While a competent DIYer can often manage the installation, we recommend a qualified plumber to ensure the pressure-reducing valves and filters are calibrated correctly for your local water hardness.

Is a boiling water tap more expensive to run than a kettle?

Surprisingly, no. While the initial cost is higher, a boiling water tap is often more energy-efficient for busy households. It maintains water at a set temperature in a highly insulated tank, costing approximately 3p–5p per day on standby (price dependant on your energy provider). Because you only dispense the exact amount of water you need, you avoid the energy waste associated with overfilling and re-boiling a kettle multiple times a day.

Are 3-in-1 boiling water taps safe for family kitchens?

Yes, our range of Boiling Water Taps includes integrated safety features such as cool-touch spouts and child-safe "push-and-turn" handles. These taps provide standard hot and cold water alongside instant 98°C filtered water, eliminating the need for a kettle and saving both time and worktop space.
