evohome: create your ideal comfort zone

With evohome, you control your home temperature room by room. Smart zoning means you only need to heat the areas you’re using, keeping you in control, saving energy and creating your perfect comfort zone.


Smart Zoning for Your Home

Your evohome lets you create and control up to 12 smart heating zones, so you can make an individual zone for the living room, kitchen and bedroom. Now you can be cosy in the rooms you’re using ­– and turn the heat down in the ones you’re not.


Control where you need it

Control your home heating and hot water when you like, wherever you are. Keep in touch via the Total Connect Comfort Intl App, web browser or voice assistants, whether at home, at work or on the road.


Energy efficient

Did you know that around 82% of your home energy bills are for heating and hot water? But with evohome smart zoning, you only heat the parts of your home that you’re actually using, saving precious energy and money.  


Different rooms need different temperatures, so evohome lets you create up to 12 individual heating zones, putting the comfort exactly where you want it. It adapts to your changing lifestyle too, whether you have radiators, underfloor heating, stored or shared hot water - you can easily add and remove zones whenever you want.

Whether it’s lowering the temperature in one room, or creating weekly schedules for each of your zones, evohome gives you the flexibility to change things to suit your plans. And because it’s wireless, it’s installed quickly, with no messy renovations.


How you control your evohome system is as flexible as you are. Whether it’s in the room, via the Total Connect Comfort Intl App, a web browser, or in sync with voice assistants, there’s an option for every lifestyle and every level of technical know-how.

Will evohome work for me?

Because evohome works with most modern boilers, including OpenTherm, you can enjoy precise control and more comfort and savings. No wonder it’s been awarded Class VIII – the highest Energy-related Products (ErP) rating for thermostat control. 

Will evohome work with my boiler?

With evohome smart control, you can make sure there’s always enough hot water when you’re home – and save energy when you’re not. Checking the water temperature or changing the schedule is easy, wherever life takes you. 

Save energy through better control

82% of energy consumed in the home is used by heating and hot water. Reduce your heating bills by controlling your heating room by room for more control, comfort and efficiency.

Upgrading your basic timer and thermostat control to evohome smart zoning could deliver as much as 40% savings on heating your home.*

Our Products

At Honeywell, we know that every home is different. Our flexible evohome products help you customise your system to suit your surroundings, so everything’s just how you like it.

Simplicity and control is at the heart of your evohome system. Use the full-colour touch screen and easy-to-follow menu to schedule, zone and personalise your temperature and hot water settings at the touch of a button.


The evohome controller provides all the information the evohome system needs to individually control each zone - these radiator controllers also allow you to control the exact temperature directly from the radiator. Keep things as toasty as you want them using your evohome controller, Total Connect Comfort Intl App or radiator controller.


Keep things cosy underfoot with our easy-to-use wireless control system. Manage up to eight underfloor heating zones around your home, each controlled like any other part of your evohome system. 


evohome works with all types of boilers - with information about the time and temperature required for heating each zone and the hot water sent wirelessly between the evohome system and the receiver boxes connected to the boiler.


Want to enjoy even more control? Our Digital Room and Single Zone Room thermostats give you another evohome control point. Wireless and discreet, they’re perfect for extra underfloor heating zones.
