Smart thermostat or Extension kit


I will install Smart Radiator thermostats at home, with my bolier. I want Smart Radiator thermostats to be able to control boiler and call for heat. Do I need Smart thermostat or just Extension kit is needed, or both?

Thanks for answer



  • You'll need the Smart Thermostat for sure!

    But the extension kit depends on you current thermostat and the wiring that goes to the boiler. If you can reuse the current wires of your thermostat and do not want to go wireless to your boiler, you will not need the extension kit.
