Single to Double RAD - Help please!

I have done a search of the forum but couldn't find an definitive answer hence this post.

I have an ancient single radiator (1600 width) that is providing insufficient heat for our hallway. I want to replace it for a double, however the depth of the single from the wall is 45mm and the double is 85mm meaning some alterations...

I am reluctant to change the existing pipework up to the TRV's as only access to pipes is via 1/2M crawlspace under the floor. Also the hallway has parquet flooring which i don't want to damage. So my question is, could I fit a radiator of a smaller width (1400) giving me an extra 10cm space at both end of the radiator. What i'm not clear on is how I then pipe to the radiator.

Looking at the push-fit connectors I could;
Use an elbow to give me the extra depth needed from the valves off the wall, and another elbow to then point towards the radiator. I might then need an adjustable connector from the elbow to the radiator.

An elbow - elbow - connector - rad, seems a bodge to me with lots of points of failure. Is this standard practice? If not I guess I need to bend some copper pipe into an 'S' myself - which sounds a bit tricky.

Any advice gratefully received ....

What your suggesting sounds horrific!

There is quite often enough play in the pipes to allow connection to a DP radiator otherwise altering the pipework before the radiator valve is better if you dont want to alter below the floor. Cut the pipe back and use a couple of end feed 90s to step the pipework out.

A wider radiator would allow the modified pipework to be hidden on the underside of the rad.

Push fit is bulky and ugly.

Like this :

Copper push fit fittings? Tectite from screwfix ( or other suppliers)

Thanks all for the help. Putting in a longer radiator would be ideal but unfortunately that's not possible. I will look at cutting the pipes back with end feeds.

Thanks, Fozzy

You could always use flexible connectors. What do you reckon to that Dan?



















I'm not serious.

Your existing rad presumably does not have any fins.

Fitting a modern finned rad will give about 30% increase in heat output.

There are many simple solutions that professionals use and most look pretty good.

Presumably the flow and return temps are correct on your rad?
