Ok, Have checked the available space and there is sufficient room to raise the F&E tank at least 500mm above the highest Rad whilst allowing the vent pipe to raise 450mm above the F&E tank. From what I have read this would seem ok!? Thanks

Open Vented system A friend of mine has a converted Oast House and wants a radiator in the gallery area which currently suffers from damp due to lack of heating / ventiliation. This is roughly level with the F&E tank in his loft area. How high above the highest radiator (ie new one in the...

Thanks for the replies. The plaster has not blown at all. The woodburner is set inside our chimney breast. The walls that show the damp are facing the room (ie to the right and left of the chimney breast) with the right hand side showing a much larger damp area (backing onto my neighbours...
