Recently had a combi fitted, power flushed the system and refilled. But now the radiators gurgle like mad. In a tank system I would open the valves on the radiators to let the air out, but since this is a pressurised system I don't know what to do. Last night at 3 o', heating fires up to keep the house above 15 degrees, my merry family nearly out their respective beds when the howling of the wolves, uh, the gurgling of the radiators started. Any advice much appreciated - do I need to call in my plumbers?
Cheers
Fred
