After much ripping and sawing and cutting, and a poop-filled cold-water interruption, the shiny new boiler is in, although the new water tank is not yet there.
The new boiler is a 40 kW Rotex A1 gas monster. It looks better without the insulation (kinda skeletal), but I suppose it needs it's coat for the winter.
In other news, a man arrived in a bright yellow GrDF van insisting that he wasn't from GrDF, but anyway dropped off some road signs promising "on attaque demain". And as I type this, another man has appeared with more signs and looks like he's about to close the road!
Our heating man has also appeared and has dropped off a large water tank (and has rushed off again).
