If your home has been feeling a little chilly lately, it could be down to misbehaving radiators. Specifically, the thermostat valve that controls the radiator’s max temperature might be faulty.
That means it’s time to replace it, and we’ve got a simple DIY guide to help you through the process below.
What You’ll Need:
-
Some towels to put under the radiator
-
A container to catch any water
-
The radiator key and/or a screwdriver
-
Adjustable wrench
-
Your new radiator thermostat
Prep Before You Start
-
Turn off the heating and wait about 1 to 2 hours for the radiator to cool completely.
-
Place towels underneath the radiator and pipe valves, and keep your water container nearby for any drips.
Step 1: Close Off the Radiator from the Heating System
Make sure no water flows in or out while you change the thermostat. There could still be water left in the radiator or pipes, which could leak hot water and cause burns or damage.
On the side opposite the thermostatic valve, locate the manual valve and turn it fully clockwise to close it. Use your radiator key or wrench for this.
If you’re thinking about replacing your entire radiator, check out options like Single Radiators or upgrade to something bigger like Double Radiators.
Step 2: Unscrew the Thermostat Head
Use the key or wrench to turn the thermostat head counterclockwise until it comes off.
For a fresh style, you might consider upgrading to Designer Radiators or stylish models like Horizontal Radiators or Vertical Radiators while you’re at it.
Step 3: Screw in the New Thermostat Valve
Place your new valve in position and turn it clockwise until it feels snug. Use the wrench or radiator key to tighten it firmly—but don’t over-tighten, or it might get stuck.

Step 4: Open Up the Radiator
Turn the valves you closed earlier back to the open position by rotating them counterclockwise. Keep your towels and container ready just in case of drips.
If you prefer a classic look, White Radiators remain a timeless choice.
Step 5: Switch the Heating Back On
Set your new thermostatic valve to the desired setting, then turn your central heating back on. Let it warm up and check the radiator is heating correctly.
And you’re done! You should now be able to control your home’s heat smoothly and efficiently.
