Can anybody tell me how these work and how they are installed? My aged but efficient central heating system has only an on / off / timer control unit.

TRVs. Thermostatic radiator valves are normally filled with a wax like substance that senses the air around them. Expand contract depending on the area to where they’re fitted and can be set 1-5. 5 being fully open more heat required. When the desired temp is reached/ drops the wax shuts off or opens the valve

A heating engineer would have to install one. Basically they are only a on/off switch. One wire comes from the boiler to the thermostat. To a spot in the house to give a average house temp. Another wire from the thermostat back to the boiler. They more often than not contain a bimetallic strip, that works on ambiance temperature. A oven on a gas cooker works normally on a bimetallic strip.
