    If you are looking for ways to save on your fuel bill then a good way to save is by changing your radiator valves.

    If you upgrade to thermostatic radiator valves you can cut your fuel costs and you also have more control of your central heating system.

    If you have let’s say 8 radiators in your home with no thermostats fitted then when you’re heating is on they are all getting hot, even though you may not need them all to be working, so the only way to stop the ones you don’t need is by closing them on the radiator valves by hand.

    If you fit thermostatic radiator valves then you have full control of that room once you have set the required temperature on the valve, then that radiator will never get any hotter.

    TRVs or thermostatic radiators valves are a good way to control you’re heating costs.

    They work by sensing the air temperature within the room, you don’t need any wires to be fitted to the boiler, they are completely manual.

    What you have to remember though is they only work when the central heating is switched on, and if the timer for the heating is in an off position then they will not work.

    To upgrade your radiator valve is a simple job to do if you are in to do it yourself.

    If that’s not you then make a call to your local plumber and ask them how much they will charge.

    If you are going to upgrade your radiator valves yourself then you need you to need to decide how many radiator valves you need.

    There are many makes of thermostatic valves on the market to choose from, some even have a digital display, but as a good make to use is Drayton. They have been around for a long time and the quality is good.

    Now you have been to your local plumber’s merchants and bought your new thermostats you are now ready to fit them.

    The first thing you need to do is turn off the power to your central heating boiler, now connect a hose to a drain off and put the hose into a drain.

    Next, you need to make sure that once you start to drain down, the system does not start to refill.

    If you have a pressurised system then you don’t need to do anything, as this has to be filled manually via a fill-up loop. if you have a tank feed system then you will need to turn the water off to the tank.

    Now open the drain off and start draining.

    Once the water starts to slow down then you need to open the air vents on the radiators, start with the upstairs ones first.

    Once the radiators are all drained you are now ready to start changing your radiator valves.

    You will need PTFE to wrap around the threaded part that screws into the radiator and boss white for the part that connects to the pipe.

    Make sure you place a waterproof sheet under the radiator, as when you start to remove the old valve some water may still be present.

    Fit the new valves make sure they are all tight before refilling.

    If when you were draining the radiators you noticed the water was not clear but dirty then I would advise flushing your system out with a flushing agent, then once clean add an inhibitor, I use sentinel x100 but you can use any make.

    This will protect your boiler and radiators from corrosion.

    Fill the heating system up and start by venting the downstairs radiators first. Now check all the new radiators valves for any form of leakage.

    Carry out a heat test to make sure all the radiators are heating up, again check the valves for leakage.

    Once the heating is up and running you can now set the temperature on your new TRVs and start saving on your fuel bills….
