When the power fails..
Our house is rather old, ranging between 90 and 110 years old dependant on the source. The precise age is a matter of detail only, the important part is that the house does not really have anything approaching modern insulation and the house radiates heat during the winter.
This is a little more expensive for us, but not a deal breaker (as we reno we’ll properly insulate the walls). When you combine this with our Canadian winters and our neighborhood history of minor power interuptions, however, it is a definate cause for concern.
I explored a few options to keep the furnace running if the grid drops. My “hail mary” option was to run the car and my 300 Watt inverter to power the furnace only. This was as far from optimal as I could get (well, just slightly less far than the other alternative of “no heat”) and lacked any elegance at all.
