Smart thermostatic radiator valves compatibility guide
How to use this guide
Compatibility with heating controls
The smart TRVs reviewed here all do much the same thing, it is the control thermostat that is the more important choice. The Honeywell EvoHome is suited for much larger properties. All six other thermostats are compatible with the vast majority of heating systems (old and new boilers) and will operate the boiler efficiently based on a learned pattern of when you need heat.
A more efficient feature of the Nest and Honeywell Evohome is that they can reduce how much gas the boiler uses – this is call load compensation. However both the boiler and control must speak the same ‘language’, called Opentherm. For compatible boilers and smart controls read our Guide to Opentherm compatible controls and boilers.
