is it possible to repair hole in central heating radiator?

Answer 1

It isn't worth the risk. Normally radiators are too thin to be repaired by welding, as the welder just cuts another hole in the metal. If not perfectly repaired the hole will come back and your house will be flooded - its really not worth the risk - plus whatever you try to block it up with might go into the system and block it up - expecially if you have microbore pipework

Answer 2

When a radiator has a hole in it, you may as well throw it away. It may be a pinhole on the outside, but it is 4 times bigger on the inside. You can try to get it welded, but once the corrosion on the inside has started it will only keep coming back. It will continue to rust over a bigger area.

Answer 3

using a bleed key go round all the radiators one by one and and open the little bleed valves and let all the air so the water comes to the top this needs to be done on all radiators, hope this helps. It often needs doing after the summer when system has been off awhile, the upstairs ones will most likley have the most air in.

Answer 4

I would think it would depend on what caused the hole in the first place. If it was inadvertently damaged, a licensed welder (certified for pressure work) would be able to assess your situation and give you an estimate.

If it rusted through, there will surely be other spots ready to go. In this case replace it.

Answer 5

it is possible with Araldite if its a very small hole. I wouldn't try welding as you will make other holes but if you are a gas welder you might have a go to amuse yourself. Chuck it out and replace it.

Answer 6

I reckon a product called "repair metal for good" would do the trick. You will find it at B&Q etc.

Answer 7

Yes, but if the hole appeared from the inside, e.g. rust, your as well to replace it.

Answer 8

yes it is
