4 in 1 Instant Boiling Water Taps 

Our 4 in 1 taps include a compact, high-performance chilling unit that sits alongside the boiler tank under your sink. Water from the mains is first purified through an advanced cold water filter tap system, then cooled to a consistently crisp and refreshing temperature (typically 3-10°C). This gives you perfectly tasting drinking water on demand, replacing the need for a separate water filter kettle or refrigerated jugs.

The chilling unit is designed to be compact and energy-efficient. While a 4 in 1 boiling tap requires slightly more under-sink space than a 3-in-1 model to accommodate the chiller, it is still engineered to fit comfortably in a standard kitchen cabinet. The installation process is straightforward for any qualified plumber.

Maintenance is simple. The single, advanced filter cartridge purifies water for both the boiling and chilled functions and should be replaced every 6 months to ensure optimal performance. The chilling unit itself is a sealed system and requires no regular maintenance beyond ensuring it has adequate ventilation.

Absolutely. Every electric hot water tap in our 4-in-1 collection is equipped with a child-safe, spring-loaded mechanism for dispensing boiling water. This prevents accidental activation and ensures total peace of mind, making them one of the best boiling taps for family homes across the UK.

If your chilled water tap is not dispensing cold water, first check that the chilling unit is plugged in and switched on. Ensure there is adequate ventilation around the unit and that the filter is not overdue for a replacement, as a blocked filter can affect flow to both the boiler and chiller.
