So I'm posting this thread a little in advance to try to collate some sensible questions etc before the chap comes - in August.
I've prattled on long and often about our energy issues, in this house, but I'll try to precis it so it's in one place and for newer members who won't have read all my other drivel

We live in an ex-MOD barracks building -single storey, built from concrete blocks and flat solid concrete roof - SW facing so it gets the sun all day from about 10am. Apart from the shop area everywhere has been insulated and dry-lined to, we think, a fairly high standard. We fitted double glazing which has made an enormous difference to the internal temperatures.
We're all electric for cooking etc - no mains gas up here and the position of our house makes it nigh on impossible to have propane , oil or LPG. I wouldn't want any of the above anyway but I'm guessing that's why none of our predecessors fitted one of them.
Central heating is run by a huge old coal boiler. Since the double glazing was installed it's been far too hot. In the depths of winter it eats over £30 of coal a week - and that's after we reduced the size of the firebox (to try to reduce the temperature) and supplemented with a trailer-load of logs (£35). We've bought a woodburner stove/cooker to replace it (an old but perfectly formed Esse Doric


I should add that we are, I'm afraid


So, eventually

1) passive solar water heating - I wondered if we could fit this as a sort of canopy over the SW facing windows. It would keep the shield the sun from the house too

2) solar PV to supplement our electricity (although that might be problematic - can't attach to the grid at the moment but I believe Scottish Hydro are sorting that soon

3) wind turbine - I think at the moment this is a non-starter

Even if we couldn't do these for the whole building I'd love to separate the supply to the workshop/shop and have that meeting it's own energy needs.
Sorry, my precis was rather long-winded
