Replacing a radiator is a job for a competent DIYer, so only go ahead if you’re confident with your plumbing skills - otherwise, call a qualified plumber. Radiator replacement is a job that should only take a few hours.
What You'll Need:
Ensure that the items in your toolkit match those illustrated on the new radiator instructional manual.
2. Drain the old radiator
- Place a bowl or bucket under the radiator to catch any drips from the manual control valve.
- Grip the body of the valve with one adjustable wrench. Hold it steady while you use another wrench to gently loosen the nut that connects this bleed valve to the adaptor piece screwed into the radiator.
- Now you need to vent the radiator of air to break the vacuum inside and allow the water to flow out of the control valve. Do this by opening the valve at the top with a radiator key.
- Hold a towel under the radiator valve to catch any leaks.
- Keep draining the water out of the control valve end of the radiator until the flow stops.
A little extra help: Plumbing involving pipework is covered by a number of safety regulations. If you’re unsure about them, talk to a professional plumber.
3. Remove the old radiator
- Once the radiator is drained, loosen and undo the nut that connects the lockshield valve to the adaptor in the radiator.
- You may have to gently push the heating pipes and valves outwards to free the connections. But be careful not to bend them!
- Lift the radiator upwards to remove it from the wall brackets. You’ll probably need an extra person for this.
- Close the valve with the radiator key.
- There’ll usually be some water left in the bottom of your radiator or towel rail, so tilt it to one side and drain this into a bucket.
- The water may be dirty, so place the radiator on old towels or sheets.
A little extra help: After removing your radiator it’s a good idea to bleed all the radiators in your system as air can move through the pipework.
