A mate of mine has been discussing problems with his CH and we all are a little stumped.
He recently had a new boiler fitted and new radiators throughout, the system was flushed prior to installation of the new boiler and a large percentage of the pipework was also replaced. Each new radiator was fitted with a thermostatic valve, but he has noted that on a couple of the radiators the thermostat appears to have been fitted on the return side( the installer has told him that as they are by-directional valves this doesn't matter, is this correct?).
They main problem for him is that when he switches his heating on he gets a gurgling noise in a couple of the radiators as they start to heat up and he gets air in his system almost weekly. He was told the system has inhibitor added.
Are these two problems related? What can he do about them???
All advice greatly received
