How to Install a Thermostatic Radiator Valve How to Install a Thermostatic Radiator Valve

What You'll Need

Installing specialist valves onto your radiator is one way of making sure that you have complete control over the hot water in your system, and a thermostatic radiator valve will help you to keep your room warm without costing you too much extra in energy bills. Installing a new valve on your radiator can be a rather daunting experience, and it is no surprise that most people choose to call in an experienced plumber to fit these devices. However, if you have a little bit of home improvement knowledge, and feel that you are up to the challenge of replacing your thermostatic radiator valve, then this can be easily done by following a few simple instructions to help you get the job done quickly and efficiently.

Step 1 - Preparation

Ensure that your water supply is completely turned off, and then run the hot water tap in your bathroom until there is no water left. You should leave the tap on, even after the water has been drained, just in case there is any lingering liquid anywhere in the system. Once the water is off, you should then bleed the radiator. Be sure to lay towels and a basin near the bleeding nozzle, and then press it inwards with a screwdriver. Allow the gas and water to escape from the radiator. You are now ready to remove the old valve.

Step 2 - Removing the Old Valve

Take your wrench, and gently pry off the valve. Most valves come off with a little pressure, but if yours has been screwed into the side of the pipe, you will need to release it using the screwdriver. Take care to keep the valve screws, as you may want to install them on your new thermostatic radiator valve. When the old valve has been unscrewed, make sure that you can pry it away. You may need to wriggle it from side to side in order to release any plumbers caulking that has been placed around the bottom.

Step 3 - Installing the New Valve

Take your new valve, and remove any packaging or plastic coverings. You should then turn the valve the right way up, and ensure that all the sections are correctly screwed together. Once this is done, place it over the end of the radiator pipe. You may need to push it down using your wrench. At this point, you can decide whether to screw it into place using the screws from the old valve. If so, do that next. Once the valve has been put into place, cover it with caulking, and leave this to dry. Once your caulk has dried, turn the water back on, and allow the tank to fill. You should notice running water from your hot tap when the system has been restored.
