Replacing radiator in a microbore system

[SteUK]

Hi chaps,

We are overhauling the whole kitchen and our plans mean we need to remove a radiator (length 1.8m). Not wanting to lose a radiator in the room (6m x 3m) we want to put one back in on the adjacent wall (not as big, planning on a 1.2m radiator). So, to the questions...

New double radiators, such as those available at wickes, screwfix, toolstation, etc are compatible with a microbore system? I fear this is a silly question but the way I understand microbore is that there is a pipe that runs from the in/out value into the middle of the radiator. How does this fit in with, what is essentially, a smaller radiator replacement.

I assume to I will have to drain the whole system and replace the pipe (current pipe is not long enough and far from straight!) back to the manifold?

Thanks!

The valve you are thinking of is or was a twin entry valve. These are no longer available so you will need to pipe the rad with a valve at each end. All rads are compatable with this set up.

Do you only have one pipe to that rad ??? Twin entry rad valves are not used anymore and if that is what you have then change the pipework for 2 single valves.
The rads from screwfix are fine for what you want.
you will need to extend the flow & return after draining down or freezing the pipes.......good luck

Yes, yes, every radiator in the house has twin pipes at a single end. So just put a valve on each end and connect up?

How long does freezing last? Long enough to cut and re-solder?

Cheers!

Freezing lasts a while with microbore depending on where the blowtorch is.
You could use compression or even pushfit.

Hope you haven't got the old 1/4" microbore as there as no adapters available to metric sizes. You would have to change to 10mm copper and 'ream' the indie of the 10mm out until you can slide the 1/4" into it then solder as an end feed fitting.

 

[SteUK]

Measuring it, it is 8mm.

Thanks for the advice chaps, think I will opt for the freezing and braze option.
