Bathroom rad is lukewarm when CH is on. When HW is on it is hot.
Had new big radiators fitted, and kept the same towel rad in bathroom. Prior to this the rad got very hot with the old rads when CH was on.
Bathroom rad has been plumbed in so it comes on with CH or HW.
But when HW and CH are on the remaining rads don't get that hot. Whilst I know the hot water is split between HW cylinder and CH they shouldn't lose that much heat as the old rads didn't.
The old rads were the first generation panel rads without convectors.
Could this gate valve have anything to do with it?
