A friend asked me to post. ferroli modena 80e combi
he had a cold radiator, so bled it, this worked ok and the rad worked, however he noticed that the pressure had dropped in what I take it is a closed loop. He then attached a pipe to add more water to the system, but now finds there is too much in there. I think he said it should be 1 bar? anyway, how does he reduce this? if he has to drain some of the water, how does he do this. cheers Coach
