One of the upsides of being a house renovator, is that every house you buy is full of surprises. Jobs you thought you would have to do that turn out to ne unnecessary nd jobs you hadn't expected.
Currently we are relieved to find that we do not have to take the roof off our 'new' home to install insulation. But, while we knew the CH boiler was defunct, we hadn't expected to need to replace the whole system because it is such a Heath Robinson jumble of randomly situated radiators on a system re using partly bigger pipes from 2 previous heating systems.
We once bought a house from a plumber. Every item of plumbing was ‘Heath Robinson’. Later the neighbours told us that if they were replacing their boilers he’d take the old one, apparently to use the bits to keep his going!
Like you were serial renovators, even when we don’t expect to replace things!
