Family of 4 - around 2400 SF - 1975 construction, fairly tight, but the insulation could be way better if I wanted to rip open all the walls (which I don't).
Electricity is typically around $90 at $0.10/KWH although the last 2 months it was under $60.
NG works out to around $100 month averaged out, this being for heat from a high efficiency boiler, hot water from an indirect tank fired off the boiler and a gas BBQ.
NG is around $0.50 per M3 which I think would be around $1.30 per 100,000 BTUs.
