How do I remove a towel radiator to decorate?
Just follow these step-by-step instructions and you’ll have a freshly decorated wall in no time.
Step 1 – Close the valves
First, you’ll need to turn off the valves by turning them clockwise.

Step 2 – Remove all containing screws
Next, use the small Phillips screwdriver and remove all the retaining screws from the wall brackets.

Step 3 – Prepare your washing up bowl
Once you’ve done this, place down the two towels and a washing-up bowl underneath either of the radiator valves.

Step 4 – Undo the valve nut
Using the adjustable spanner, undo the valve nut and pull the open outlet over the bowl.

Step 5 – Drain the towel radiator
Allow the water to drain into the bowl.

Step 6 – Open the bleed valve
Once the water has stopped open the bleed valve using the radiator key – this is to remove any remaining water in the radiator.

Step 7 – Move to the other valve
Close the bleed valve and undo the other nut on the valve at the bottom of the radiator.

Step 8 – Remove & empty your towel radiator
The radiator is now ready to be removed. Gently pull the radiator away from the wall, and pour any contents into the bowl.

Step 9 – Make sure it is completely empty
Once you’ve removed the radiator, pour any remaining contents into the bowl, and the turn the radiator upside down to avoid any drips.

Step 10 – Remove the brackets & get decorating
Remove the remaining brackets using the large Phillips screwdriver.
You are now ready to decorate.
Once you’ve finished decorating screw the brackets back into the wall and you can refit the radiator.

Tighten back the valve nuts and open the valves fully anti-clockwise.
The radiator is now ready for filling.
If you have a pressurised system slightly open the filling loop to top the system pressure up whilst filling.
Step 11 – Bleed the towel radiator
Bleed the radiator until it’s full of water again – it should spurt out from the bleed valve.

Step 12 – Check the boiler pressure
Shut off the filling loop on your boiler between 1 and 1.5 bar.
Get someone to help to monitor the pressure to ensure you don’t over-pressurise the system.

Turn the heating on and allow the system to warm up, the heated towel rail should be piping hot.
