Good point ajrobb. However, his theoretical radiator load will be further reduced if the TRVs start shutting down which is why it might be worth experimenting with a lower boiler temp and then obeserve what actually happens at the boiler. If this allows the TRVs to stay open and leave the...

Yes the best thing now would be to reduce the boiler temperature by, say 5C) and see how that goes. It is having the boiler temp too high that causes the room overheating which causes the the TRVs to shutdown which reduces the flow which then causes the bypass to kick in!) the ideal would be...

You have missed the point or maybe I worded it badly. The hottest water with a top feed will tend to be be at the top of the radiator, the coldest will be at the bottom. However, there is, of course, a flow of water into and out of the radiator and so some mixing occurs meaning that some of...

Oh yes and thanks for the welcome. I have been lurking for a while and just wanted to share my experiences. So long as heating system designers/operators think about ways of making the return water as cool as possible then the nation's huge investment in Condensing boilers might actually start...

I'm talking about the temperature drop across EACH radiator being at least 10C. In practice I can usually achieve stable heat distribution with a 15 degree or less drop but I have never managed 20 in a free-flowing situation. Locking down the lockshields any further results in poor warm-up...
