Replacing your radiator helps you maximize your heating output and efficiency.

The process I am going to follow shows you how to replace a radiator when your heating system is supplied by a header tank, which is often located in the loft.

Fully close the lock shield valve keeping note exactly how many turns it takes. Shut the thermostatic or hand wheel valve.

Release the water pressure in your radiator by opening the bleed screw, have a bowl ready to capture any water place a container under the radiator and valve.
Then slowly and carefully undo the lock shield valve connector nut and drain off the water.
Undo the connecter nut from the other valve so you can lift the radiator off the wall brackets then carefully tip out the water.

Remember radiators are heavy so you might need an extra pair of hands lifting them on or off the brackets.

With the radiator off the wall you may like to take this opportunity to do any decorating the might have planned.

Remove and clean off old PTFE from the radiator valve tails using a tail key and apply new PTFE ready for fitment to a new radiator.

If you are replacing radiators in each room I would recommend replacing the thermostatic valve these will allow you to pre-select the temperature separately in each room.

It is important to get the tape wrapped around the valve in the right direction, so if you are holding the valve in your left hand make sure the tape is rotating around in a clockwise direction.

You can then remove the wall brackets.

Position the new radiator as far from the wall as the valve outlets are above the floor mark lines on the wall opposite the radiator brackets in order to position the replacement radiator.

Position the first bracket against the vertical line for the mark you have made at the bottom notch alignes.

Position the radiator adjust the match of the valve connections by removing the radiator, loosening the bracket screws and sliding the brackets if necessary mark one of the round fixing holes in each bracket.

When it is correctly positioned drill and plug pilot holes, then replace and fix both brackets before hanging the radiator back on the wall. You will need to replace the tail key and bleed valves.

If you are using a pressurized heating system it may experience a drop in pressure tripping out the boiler.

If this is the case you will need to add additional water via the filling loop to maintain pressure.

Hang the radiator on the brackets and tighten the connectors onto the valve. Brace each valve with a wrench as you tighten the nut fully.

It is important to make sure the header tank is topped up with corrosion inhibitor.

Open both valves by the number of turns it took to close them off

Bleed the radiator using a radiator bleed key.

Once the job is complete always check for leaks and ensure your heating switched on.

Remember radiators are heavy see you may need an extra pair of hands lifting them off and on the brackets.
