My current Trianco oil boiler is faulty, and Trianco went out of business last year, so no spare parts available. This is a standard boiler, with flue through an external wall. The current oil tank is housed in a barn/workshop but with no retaining wall, installed before the regulations required this.
I'm wondering whether to go for a replacement oil or lpg boiler, the lpg having less moving parts and quieter? What I don't know is the current installation regulations I'd need to comply with, mainly siting of tank, since I have no private land other than the barn in close proximity to the house.
Can an lpg tank be installed without a surrounding wall?
Can it be in the barn/workshop?
If I get a replacement oil boiler would I need to have the retaining wall?
Can it still be in the barn?
Anything else I may have forgotten or not know about?
