How much are you spending on heating per day during this coldspell?

Agree about the insulation, though it turns out that the DG is a loss maker.
The cost of heat-loss through SG windows[1] doesn't even pay the interest
on the cost of having it installed. DG cost: £5200, interest @ 5% = £260 p.a.
MOST savings on DG come from replacing leaky, rotten and draughty
windows with ones that seal properly.
Not from the actual DG itself!
[1] Heating fuel savings (est. 20% of _heating_) = ~ £50 p.a.
