Plus at -40C, how do you keep up? You are battling everything being cold, including the ground under you. People in this thread are saying "just heat always..." wha?! Heating an insulated home is crazy expensive at -40C, and you want to heat a driveway from -40C to 10C, and melt all the snow?! (Heating to 0C is not sufficient to melt and let stuff run off, it will freeze again too fast.) And beyond that, now the end of your driveway is solid ice. Or it will be, as the drain freezes. A gas snow blower is better for the environment, 100x better, than that.
