How to replace your radiator

Installing a new radiator in your home can be beneficial to the overall style of the room, and the efficiency that is produced by the radiator, cutting your heating costs in the process. Read below to find out how to replace your radiator, including both the removal and installation stages of the process.

radiator labelling here are components of the radiator that will be integral during the replacement.

 

Removing the radiator
Removing the radiator is probably the messiest part of the jobs, so you will need a couple of buckets or bowls to catch any released liquids.

1st radiatorThe first call of action is to close the lock shield valve. Whilst you do this, you will need to take note of how many turns you make, for later during the installation process. This then needs to be followed by shutting off the thermostatic valve.

After both of these valves have been shut off, you will need to release the water pressure from the radiator, and this is where your buckets or bowls will be used. The first part of releasing the water pressure is bleeding the radiator, using a radiator key, let the water to drain into your container. if you are unsure on how to accomplish this, click here to check out how to bleed a radiator.

The lock shield valve connector nut then would need to be unscrewed, and there should be a large amount of water that drains from this. This process would then need to be repeated from the other connector, so you are able to lift the radiator from the wall brackets. (be prepared, the radiator may be too heavy for one person to lift)
As you remove the radiator from the wall brackets, you will also need to remember that there will still be some excess water left in the radiator, so this will need to be carefully poured from both connector points, into your buckets.

The radiator valve tails would then need to be removed using a radiator valve tail key, at the same time as cleaning and removing the PTFE tape that’s already on the valve tails. This tape would then need to be replaced and this would need to be done in a specific manner. So, if you are holding the valve in your left hand, you would need to apply the PTFE tape in a clockwise motion.

Installing a radiator
The wall brackets can then be removed, and the measurements of the replacement radiator can be made on where the new brackets should be attached to the wall, and how far from the wall the new radiator would need to be positioned. Marking lines on the wall with a pencil will be very helpful as a guide to where you want the replacement radiator to be positioned. This may take a couple of attempts to perfectly align, but adjustments can be made to the brackets to ensure a perfect alignment.
Before the radiator goes back onto the wall2nd radiator, the tail keys and bleed valves will need to be screwed back into place. When you place the radiator into place on the brackets, make sure you tighten the connectors. Using a wrench in this instance in advisable as you tighten the nuts fully. This is when you need to remember the number of turns it took earlier to loosenthe valves, as they need to be re-tightened by the same number of turns.

Finally, you will need to bleed the radiator once more, just to ensure you are getting the maximum usage from the radiator, and that the energy efficiency is as high as possible. Before turning on your radiator, you would need to check for any leaks, and ensure your boiler header tank is topped up with corrosion inhibitor.

If you have followed these instructions efficiently, you will be able to turn your radiator back on and have it working at its highest capacity. If, however you feel uncomfortable or unsure at any point of this process, please seek help from a qualified plumber.
