I recently had my back boiler replaced by a combi. all the rads seem to
be working fine except the bathroom. It remains cold

[sparx]

Poss. rad was on hot water circuit as bypass for old system, & to give heat to bath room when main heating off. Therefore now may only get warm when water being drawn or not at all depending upon where in old circuit it is tapped off.

Check that both rad valves are fully open. If a TRV is fitted, it may be stuck shut. Take the top off and push the pin down. It should move up and down about 3-4 mm.

If both valves are open, with the heating on, go round the house and shut off ALL other rads. This should force the water into it and remove the blockage. (Assuming it's not as Sparx says.)

Or the valves are SHUT

Thanks everyone for your help. I think I have solved problem. When combi was Installed TRV's were fitted to the bedroom rads by turning them down a bit the bathroom rad gets hot.
