A boiler - woo!

The boiler is now in situ. How the bloke managed to get it up into the loft on his own is still a mystery, but it's there, fixed to the wall, and mostly plumbed in.

Its on the gable-end, with the flue vented out through the wall under the eaves. It connects to

the rest of the house plumbing via the airing cupboard, which has mains cold water, as well as DHW and CHS pipework from the old system.

Thoughtfully there's also a pressure gauge and a filling loop fitted at that level, rather than having to scuttle up into the loft to check such things.
