Existing thermostatic radiator valves can be easily replaced by eTRV within minutes by simply unscrewing and replacing with eTRV.
If the property does not have thermostatic radiator valves then eTRV needs to be fitted professionally.
eTRV gives realistic potential for 25% energy savings. Three programmes each day maximise savings and the precise thermostat reacts quickly, improving comfort. Fitting to existing or new heating systems is simple and can contribute to making substantial reductions to UK carbon emissions.
