I'm still working that out (the first bit) the last few winters have all been a bit different. We've just completed our third winter in our new house, a 3 storey Lindal designed house that was fully imported from the USA by a local high flying stockmarket trader who then ran into strife sometime around October 1987. Apparently something bad happened to the stockmarket. He went broke just before the place was finished. We bought it from the lady that bought it at the mortgage auction but that lady and her husband didn't want to spend any money on what became their holiday house. Didn't worry about little things like insulation in finishing up the joint. I believe that insulation helps to lower your heating costs. Etcetera.
Anyway. Roughly speaking, we're going through about 15 cubes, or 4 cords plus or minus. Our heater is a Norseman GLX which is meant to heat 35 squares and puts out about 10KW IIRC. It's a big unit for an indoor wood heater over here. We also have gas hydronic heating which I plan to convert to wood soon. Typical winter top temps are about 7 deg C and overnight temps down to -2 deg C on a clear night. Not super cold but cooler than you'd like. The thing that really kills us is the design and insulation of houses here, it really is rubbish. We're in the process of renovating and updating the place which will make a difference.
Our old place which was much smaller, we'd burn about 6-8 cubes per year, about 2 cords.
