The correct heating controls allow you to keep your home at a comfortable temperature with very little waste of fuel or heat, and it will also so drive down your Co2 emissions and give smaller heating bills. If your home has a system of water-filled pipes and radiators fed by a boiler, it is called a ‘wet’ central heating system. The old way of controlling the heat from a radiator, was by using a manual valve, and a fitted thermostat. A Barking Plumber is skilled and can fit a thermostatic radiator valve.The thermostat was usually fitted in a lounge or hall. That was fine, however, to satisfy the current energy and heat saving requirements, this does not provide an accurate temperature spread for the whole of the house, therefore a huge variation in room temperatures would exist. The best way to rectify this would be to keep adjusting the manual radiator valve on the radiators, and that is not practical or energy efficient.
The best solution is to fit TRV’s (or thermostatic radiator valves) as these allow each radiator to produce heat at a pre-set level. In almost all situations, and the fit would normally just be a straight one for one swap with the manual valve. Barking Plumbers can fit thermostatic radiator valves in a central heating system.
Isolate and drain the heating system. Once the system is empty you can loosen the two cap nuts on the valve and then, undo both nuts completely and lift the valve together with its cap-nut and olive from the end of the pipework.
Dress the pipework end with some wire and place the cap-nut and olive of the TRV on. Ensure that you hold the new valve and screw the cap-nut on the TRV. Always make sure the olive is fitted in the correct way. Do not tighten fully just yet. If needed you can fit a new connector on the radiator, this allows a proper fit to take place. Wrap PTFE tape around the threads. As long as they are lined up, you can begin to tighten both cap-nuts fully.
Finally, refill the heating system and do a check for any water leaks. Now you will be able to set up the TRV as recommended in the manufacturer’s instructions.
