    Step 1: Turn Off the Heating and Water Supply

    Safety first! Ensure your heating system and water supply are turned off. For combi boiler systems, this step is straightforward. However, if you have a conventional system, it's best to seek help from a registered heating engineer.

    Step 2: Identify and Prepare the Radiator Valves

    Understanding your radiator valves is crucial. Most radiators have two valves: the lockshield valve (controls water flow) and the on/off valve (either manual or thermostatic).

    Step 3: Release Pressure and Drain the Radiator

    Using a radiator bleed key, open the bleed valve to release any stored pressure. If your lockshield valve has a drain-off, you can use it to drain the radiator. Place a container underneath to catch any drips.

    Step 4: Remove the Old Radiator Valve

    Carefully unscrew the old valve. Keep a towel handy to catch any water. Use a spanner to loosen the nut connecting the valve to the pipework.

    Step 5: Install the New Radiator Valve

    Slide the new valve onto the radiator tail, and use PTFE tape to prevent leaks. Connect it to the water pipe, tighten the nuts, and attach the thermostatic valve head.

    Step 6: Final Checks and Re-Pressurizing

    Open the new valve and turn the heating system back on. Check for any leaks, re-pressurize the system, bleed the radiator, and ensure everything is working correctly.
