Never heat your whole home again! Tado's Smart Radiator Thermostats can replace your existing thermostatic radiator valves and provide room-by-room scheduling and control, so you can enjoy greater comfort and improve the efficiency of your heating system. To benefit from Tado's Smart Radiator Thermostats, you must also install a Tado Starter Kit. This product can be easily self-installed - simply unscrew your existing thermostatic radiator valve, replace this with a Tado Smart Radiator Thermostat (using one of the 6 adaptors provided if required), and add the device in your Tado app. The new universal radiator thermostat can be mounted both vertically and horizontally, depending on the type of radiator. The highly rated Tado app enables you to individually schedule and control each Smart Radiator Thermostat from anywhere, as well as providing insights and reports about the climate of individual rooms and showing you the energy savings made by Tado. Tado is also compatible with Amazon Alexa, Apple Home Kit and Google Assistant. The thermostats can optionally be operated with Panasonic Eneloop AA 1900 mAh Ni MH batteries (the use of other rechargeable battery types is not recommended). The smart way to control your heating in individual rooms. Easy to install when replacing an existing Thermostatic Radiator Valve (TRV).
