I have an issue with our open vented heating system.
The system was fitted around 7 years ago and has worked with no issues.
I have just fitted 4 new designer rads and a heated towel rail. Re filled and bled the system, and balanced the rads. The issue i have is, when the boiler turns off, water comes out of the header tank.
I have tried turning the pump down as I thought it was drawing air in via the vents pipe. But it's made no difference. Live in a bungalow so the header tank is only about 3 foot above the boiler.
Never had an issue before fitting the vertical rads.
Could they be the issue.
