Turning the heating on

Today we got the boiler fired up, and the heating running on the first and second floors. There's still more to do on the plumbing, but it felt like a major milestone to actually heat the place up! I intend to give it a longer run tomorrow to see how the building envelope performs in terms of heat retention.

A fuller write-up of the heating system eventually used to follow in the next few days. For now I'll summarise - we've used a Worcester Bosch "system" boiler with floor-by-floor programming of heating times and temperatures, and an external weather compensation controller, together with a Navitron 250 litre cylinder which will supply hot water in conjunction with the solar thermal collector (this part still to be done). Here's a recent photo showing the boiler install in progress:

Other trades have also been progressing - second fix electrical and joinery, etc.
