This morning at 7:45am when I finally dragged my arse out of bed, the bedroom radiator, on an east facing wall, was almost cold. The one in my en suite bathroom was a little warmer, probably because that room is on a corner and has two external walls. Coming downstairs, there was no discernible change in room temperature. The radiator by the front door (possibly the coolest spot in the house) was quite hot, but - with a TRV system, you have to have at least one radiator which
does not have a TRV, and this is the one. The kitchen radiator which is towards the middle of the house was tepid. The one next to my desk was the same as both of these are against internal walls. The one on the far side of the room was quite warm, but that's against a wall which used to be an external wall which now abuts the conservatory, which is not heated - at least not by central heating. I use a calor gas stove to heat that.
As the sun moves round, the south facing bedrooms will benefit from solar gain, and consequently their radiators will begin to shut down.
It all works remarkably well!
