Brrr. We have an air source heat system. We've lost the ground floor underfloor heating, but still have hot water and upstairs rads working as normal.
Any plumber within 1000 mile radius is busy and i'm struggling to find someone who can help. I'm told that the problem may lie with the 3 port valve and is more a plumbing issue than a renewable enery engineer problem.
Can anyone shed any light on what needs whacking to make it warm again?
Here's the gubbins.
Appreciated.
