The plumber is coming at "tea time" tonight to bring the new boiler he's fitting on saturday. Apparently he's just going to fit it to the cellar wall and do the actual fitting and moving of old boiler on Saturday.
Here's the setup as it is:
On the left is the boiler - above the oven in the corner of the kitchen. No idea why it's up there. On the right is the hot water tank - above and to the right of the boiler and in the spare room, behind the built-in wardrobes.
Here's where the new boiler is going:
It's down in the cellar - out of the way. The hot water tank will no longer needed as the new boiler is a combi type (well, it's a condensing one, but the principal's the same. is it not?).
