I have just had a look at a property I own that is rented out. The combi boiler is installed in the cellar but does not have an overflow attached to it as it is below ground level and there are no drains.
Will the boiler be fine as it is or do I need to fit an overflow connection. If I need to fit an overflow, can it rise from the bottom of the boiler and up to the flue level, before it goes outside without any problems?
Many thanks in advance for any comments.
I think you mean a pressure relief pipe. It can rise. When outside have a downwards looking elbow a short piece of piece and an elbow facing towards the wall.
Yes, sorry, I meant a pressure relief pipe. It's the one that opens up at 3-bar. What are the consequences of doing nothing?
Damp cellar..?
Not sure about the full regulations here but there is a duty of care involved in that the hot discharged water shouldn't be able to injure anyone.
