I appreciate your replies. The air doesn't happen until about 45mins into the cycle, but then there is a large thumping gurgling sound. I have air vents in, one on outlet from boiler and one above hot tank.
The air only happens when the heating is on but who knows, maybe it is only pumped round...
Hi,
My heating system was changed from a vented to unvented OIL system.
I have a magnaclean, nearly all the radiators are new.
The maganclean is cleanish after months of use.
I keep getting air in my system, and before you chastise me, I swear I cannot see any leak.
The pressure keeps...
My mains water flow dropped off the other week. No leaks, pressure good. Elbow fitting from Toby copper pipe to plastic pipe just inside my garden. Turns out there was a piece of plastic in my pipe, couldn't go any further into my pipe so plumber was able to pull it out after opening fitting...
