A boiling water tap uses a boiler tank that is installed below the sink and plugged into your mains, maintaining a constant supply of piping-hot water. When you turn the boiling water handle on the tap, the water is released from the tank and is delivered instantly to your sink.
The boiler tank is often supplied with the tap and comes in a wide range of capacities, from 1 litre up to 6+ litres. All of our taps come with a 2.4L boiler tank included in the price, which is compact enough to fit into the majority of kitchen cupboards - 2.4 litres of water is roughly 7-8 cups and the tank takes around 4 minutes to reheat. Larger tanks require more space, of course, which can be difficult to manage in a small kitchen.
Despite being powered electronically, the boiling water tap's tank is insulated against heat loss, which makes it energy-efficient. Maintaining water at a high temperature also requires surprisingly little energy compared to boiling water from cool, as kettles do. If you use the kettle multiple times every day, a boiling water tap is unlikely to cause any increases in your daily energy use.
If you're wondering what the difference is between a 3-in-1 and a 4-in-1 tap, it's all in the filter. Both types of boiling tap can dispense regular hot, cold and filtered boiling water, but only the 4-in-1 can dispense regular hot and cold water, filtered boiling water and filtered cold water. This is provided by a high-quality carbon filter that removes impurities from unfiltered water, purifying it and delivering crystal-clear H20 every time.
