I have a potterton Netaheat 10/16 heating only working up stairs?
I have a potterton Netaheat 10/16 it fires up but i am only getting heat in upstairs rads and not down stairs, i have closed all valves upstairs to try and force through to downstairs rads to no avail, also when i turn the thermostat up to full boiler does not fire, surely this should fire when demand is asked for, can anyone advise?
