Honeywell Home Evohome

Radiator controllers (the Wireless Radiator Controller at the current product price) replace individual TRVs so you can control each radiator separately, ideal if you want room-by-room heat without changing your boiler. A Radiator Multi Zone Kit bundles several radiator controllers for controlling a group of rooms together. The WiFi Connected Thermostat Pack gives central or hub control plus app connectivity so it suits a smaller home or if you prefer managing zones from your phone; combine the WiFi pack with individual radiator controllers if you want full room-by-room control.

Yes, Evohome's smart zoning lets you set separate temperatures per room by using radiator controllers or separate zone thermostats, so you only heat occupied spaces and save energy. set your living room to 21°C in the evening while keeping unused bedrooms at 16°C, and the system will only call for heat in the living room radiators. The system also supports wireless control and open window sensors that temporarily stop heating a room when a window is detected open.

Evohome radiator controllers are designed to replace traditional TRVs on most radiators, while the Hot Water Kit is made to control cylinder or hot water scheduling, so the parts match common setups. If you have a sealed system, combi boiler or a stored hot water cylinder, there are suitable Evohome components to manage radiators and hot water separately. Check the specific product pages for detailed compatibility notes, but typical installations use the WiFi controller with radiator valves and the hot water kit for separate water scheduling.

You save by heating only the rooms you use and avoiding wasted heat when windows are open; zoning plus app control often reduces unnecessary heating hours compared with a single central thermostat. Open window sensors stop a heated zone from calling for heat if a window is detected open, preventing wasted fuel during airing. Real savings vary with your habits, but controlling individual radiators and using schedules through the WiFi-connected controller typically delivers noticeable drops in energy use.

Start with a single WiFi Connected Thermostat Pack to get app control and central scheduling, then add Wireless Radiator Controllers (the current product price each) or a Radiator Multi Zone Kit as you expand room-by-room. That approach lets you trial smart zoning on a living area first, then add valves in bedrooms later, avoiding a large upfront cost while building a full Evohome setup over time.
