@squarepeg77
Welcome to the forum.
The value given for 'Total Output of Heat Emitters: 7.4kW' seems rather low. Is this at the standard 50C Delta T?
@derek-m 7.4kW is the sum of the “output at design temperature” figure from my radiator schedule.
Ah, sorry. I don't have that figure to hand.
Although from memory I think the output at Delta T of 50C is a bit less than 2x at our design temp of 50C max flow.
An update on my system:
