I have a Y plan heating system and when the hot water is heating up on its own the water is backing up via the vent pipe and depositing water into the FE tank. The speed is set a 1 on the grundfos pump. When the Rads are on their is no water being deposited in the FE tank via the vent even if I put the speed upto 3 on the pump. Although one of the rads does bubble quite badly.
To try and get rid of the noise and problems Ive so far had three engineers who are puzzled by it and as a last resort I go the system power flushed and the problem still exists.
Does anyone know what elese I should look at without spending more money on a heating engineer.
