Replacing a radiator

[tankie]

I want to change a radiator on a microbore system, can I use any radiator or do I need to do something with it, to take the single connection. Obvisouly I will need to stop one end, but when I looked at the current rad, connection there is a small plastic pipe disapearing into it. Any help appreciated. Thanks

You aren't likely to find any rads that will take a twin-entry valve, so convert to separate valves at each end of the rad. That will allow you to fit TRVs.

Thanks for help and prompt reply. is this just a straight cut double entry valve of a run new to either end with a trv in one? Anything to watch out for i.e. getting trv on the right pipe?

Most TRVs are bi-directional so can be fitted in flow or return, either vertical or horizontal. Normally one of the two pipes would be extended to the other end of the rad, but as an alternative you could take the flow pipe to the top tapping above the existing valve tapping.
