Step 1: Isolate Supplies and Drain Down the Heating System

Before you start any work, you need to isolate the supplies and drain down the heating system. This will prevent any water from spilling out and damaging your floors or carpets. You can do this by turning off the main water supply and opening the drain valve on your heating system.

Step 2: Remove and Discard of the Old Faulty Thermostatic Radiator Valves

Once you have drained down the heating system, it’s time to remove the old faulty thermostatic radiator valves. You can do this by using a spanner to loosen the nuts that hold the valve in place. Once you’ve removed the nuts, you can pull the valve off the radiator. Be sure to discard of the old valve properly.

Step 3: Supply and Install a New Honeywell Thermostatic Radiator Valve

Now it’s time to install the new Honeywell thermostatic radiator valve. You’ll want to install it in the same place as the old valve. Make sure you make the relevant plumbing connections to ensure it functions properly. You can do this by using a spanner to tighten the nuts that hold the valve in place.

Step 4: Add Chemical Inhibitor to the Heating System

To help prevent sludge and scale building up in the system, you’ll want to add a chemical inhibitor to the heating system. This will help keep your heating system healthy and functioning properly. You can do this by pouring the inhibitor into the feed and expansion tank.

Step 5: Refill the Heating System, Vent Radiators and Test

Finally, it’s time to refill the heating system, vent the radiators and test everything. You can do this by opening the main water supply and allowing the heating system to refill. Once it’s refilled, you’ll want to vent the radiators to remove any air pockets. Finally, test everything to make sure it’s working properly.

So replacing faulty thermostatic radiator valves is a relatively straight forward process that can help keep your heating system healthy and functioning properly. By following these steps, you can ensure that your heating system is working as well as it should be.
