Fit a TRV




The single thermostat as it was known and fitted, is really quite old fashioned and outdated now, as sadly with heating now trying to be green and energy efficient, this arrangement doesn't take into account local variations in temperature, in the home, with some rooms too hot or cold unless constant adjustment of the manual radiator valves takes place. The best idea is to fit thermostatic valves, as they open and close automatically and respond to room temperature variations. Shoreditch Plumbers can fit thermostatic valves. Most of these TRVs will be a one for one swap for the manual radiator valve. However, before attempting to change, check that they will fit.


To fit:

To begin you will need to drain the heating system and remove the old valve from the radiator. Before removing it completely, slacken off the nut holding the valve to the pipe, unscrewing both nuts fully and lifting the valve together with its capnut and olive from the end of the pipe. There will be no requirement to remove the radiator to carry out this job. Clean the end of the pipe with wire wool and put the cap nut and olive for the new valve onto it. A Shoreditch Plumber can replace this type of valve. Holding the valve in place screw the capnut onto the valve, ensuring that the olive is seated properly. Do not tighten the cap nut completely at this point. Fit the radiator with the new connector if necessary, wrap a few turns of PTFE tape around the threads, make sure that the valve is square and start turn the cap nuts fully.


Fitted:

Once complete are you are sure that all connections are tight and safe, you can refill the system. When the system is filled, you can set the TRVs in accordance with the manufacturers instructions. All the radiators will need to be balanced if no leaks occur.
