Our recommendations

Easy upgrader. Energy saver. Wiser.

If you have existing TRVs, your upgrade to smart radiator thermostats by Wiser couldn’t be easier.

  • Mount on to existing radiator valves
  • Simply screws on - ring nut provided
  • Battery operated – no wires no fuss
  • Adaptors provided
  • Add up to 32 per system


Multi-roomer. Signal booster. Wiser.

Larger home? Or thick walls? Boost the RF signal to all Wiser radiator thermostats by adding a smart plug.

Not only will you enjoy all the benefits of multi-room control without the inconvenience of lost signal, but you can control and schedule electrical devices connected to the Wiser plug, in the Wiser Heat app alongside the rest of your smart heating controls.
