City Plumbing

The evohome radiator multi-zone kit includes 4 wireless radiator controller heads, allowing you to control the individual temperatures of up to 4 rooms. Different rooms need different temperatures, smart zoning means you only need to heat the areas you are using, saving energy and creating your perfect comfort zones. Slim and ergonomically-designed, the battery powered controllers will fit most standard TRV bodies and are quick to install due to the simple lock mechanism. They feature a flip-up backlit screen and two-year battery life with a battery low reminder visible on both the radiator controller screen and the evohome controller. The controllers use two-way wireless communication with the evohome controller to ensure that commands are received and valves opened while maintaining boiler interlock. Easily add additional packs or individual controllers to create further zones.
