3 in 1 Instant Boiling Water Taps 

Our taps are engineered to heat water up to 98°C, which is the optimal temperature for making tea and coffee without scalding the leaves or beans. Dispensing water at a rolling 100°C can cause spitting and is less safe. 98°C provides all the benefits of boiling water instantly and safely.

While a standard instant boiling water tap (a 3-in-1) provides regular hot, cold, and near-boiling water, a 4-in-1 tap adds the extra feature of filtered cold drinking water.

A 5-in-1 tap offers even more convenience by including all four of those functions—hot, cold, filtered, boiling —plus filtered chilled water, all dispensed from a single fixture.

Absolutely. While the initial investment is higher than a kettle, the long-term value is significant.

An ARNO 3-in-1 instant hot water tap is engineered for efficiency. The insulated tank uses very little energy to maintain its temperature, meaning you only heat the water you need. Compared to repeatedly boiling a kettle (often with more water than necessary), our taps can reduce energy consumption, making them a smart and cost-effective choice for the modern home.

Our 3 in one boiling water taps are designed for a straightforward installation. Each unit comes with a comprehensive guide suitable for a competent DIYer or any professional plumber. The compact boiler tank fits neatly in the cupboard under your sink, and all standard connections are included. There’s no need for specialist tools, making the setup process smooth and efficient.

Safety is paramount in our design.

Every ARNO 3-in-1 boiling tap features a child-safe spring-lock mechanism. To dispense boiling water, you must consciously push down and turn the dedicated handle. It cannot be turned on by accident, and the handle automatically springs back to the off position when released.

Furthermore, the spout is insulated to remain cool to the touch, providing complete peace of mind.

Minimal maintenance is required to keep your tap in perfect condition. The most important step is replacing the boiling water tap filter cartridge every 6 months (or more frequently in hard water areas). This ensures your water remains pure and protects the boiler tank from limescale build-up.
