Thermostat Guide

Not sure which thermostat you need? The icons for each product below show what it can control, whether it connects to Wi-Fi with a phone app, and how it is installed. A green tick means yes, a red cross means no.

Our top pick: for underfloor heating and hard-wired infrared panels we recommend our Smart Wi-Fi Thermostat, 16 A, with floor sensor. Wi-Fi is built in and the floor sensor is in the box, so there is nothing extra to buy.

What the icons mean

Infrared panels: Can control infrared heating panels.
Underfloor heating: Suitable for electric underfloor heating (heating film or mats). Comes with, or connects to, a floor probe that protects the floor from overheating.
Wi-Fi & phone app: Connects to your home Wi-Fi so you can change the temperature and schedule from your phone.
Voice control: Works with Amazon Alexa and Google Assistant voice control.
Hard-wired: Wired into the mains supply by a qualified electrician.
Plug-in: Plugs into a wall socket, no electrician needed.
Battery, wireless: Runs on batteries and sends its signal wirelessly to a receiver, so no cable is needed at the thermostat.

Which one do I need?

  • Underfloor heating film or mats: our Smart Wi-Fi Thermostat, 16 A, with floor sensor is our top pick. Other hard-wired thermostats with a floor probe also work, such as the Programmable Touch Screen Thermostat, WiFi Touch Screen Thermostat or Heatmiser V3. Never use a plug-in thermostat for underfloor heating.
  • Hard-wired infrared panels: our Smart Wi-Fi Thermostat, 16 A, or any of the other hard-wired thermostats, or the V22 wireless thermostat with a V23 receiver if you want no cable to the thermostat.
  • Infrared panels or heaters with a plug: the Smart Wi-Fi Plug-In Thermostat (up to 2.5 kW).
  • Herschel Select XLS heaters: the Herschel T-MT, T-PL or T-BT, which pair wirelessly with the heater, or one of the general thermostats above.
  • A whole home with several rooms: the V24 WiFi control panel with V22 thermostats and V23 receivers.
