Don’t make the mistake of installing a thermostatic radiator valve in your bathroom, as the heat produced by your shower or bath will wreak havoc with the TRV’s thermostat. Instead of preventing the condensation that often hinders bathrooms, the TRV will shut off and do nothing.
Another consideration is to not fit thermostatic radiator valves in the same room as your principal thermostat. This unit connects directly to your boiler and so you will inadvertently create a competition between your TRV and central thermostat. In this monumental battle, the only loser is the homeowner!
