Sorry about this but I cannot seem to find an answer anywhere - what is meant by the term "a balance rad"? which I have seen used bur not explained. It seems to be a radiator on the system with no TRV on it but for what purpose?
Secondly, should you try to include it in balancing or should the flow & return be both fully open?
