We’ve moved into a property about 6 months ago, we have a aviant boiler fitted in 2022 but after having trouble with some radiators not heating up we got a couple changed, and found out we have a one pipe system. Since finding this out and reading up on it I think we need to get this made to a 2 system asap would help heating downstairs (lounge seems to be last in to get the heat) and before we have new flooring laid. can anyone tell me a good price, I’m really struggling to get more than 1 quote.
