Fitting a 700mm Wide Radiator in place of 1440mm Radiator - Question

[andre1990]

Hi Folks,

As per title, installing a double panel radiator that's approximately half the width of its single panel predecessor.

I was hoping (for the time being) to not have to cut the existing pipe and soldier new connections, and was thinking of using 2 x ~400mm valve extensions, but they only seem to go upto around 70mm max length.

The piping is close to the wall so would be difficult to cut with a circular cutter - its a job in totality that I would rather face another day hence putting it off.

Any ideas of options without cutting and relocating existing valves?

Thanks

There are no realistic options. One feed pipe and valve will need to move.

Ignoring the question: Why? and,

Assuming std 1/2"/15mm plumbing:

Remove a rad valve and replace with compression elbow. Use appropriate length pipe pieces to get to/from the rad.
You can use a straight rad valve to connect to the rad (saving yourself from using scrd union)

Or just make your own tails with pipe and a scrd union as required.

Will look rubbish, but it will work if looks are unimportant.

1. Don't forget that the distance from the inlet / outlet pipe centres to the wall will be different for a double as opposed to a single. So you will have some pipework to change unless:
1a. There is sufficient movement in the pipes to accommodate the difference. And / or:
1b. You can use the long / short side of the mounting brackets to make up the difference.
2. You are unlikely to get the same amount of heat out of a double at half the width as you do from a full width single, assuming same height.
