I think the Tesla battery & electricity in general to heat a home is a long shot and certainly not the best, including the contextual reasons cited by Karl North. I still think geothermal is the way to go if only to heat a home up to 60s, then boost it up to comfort level by any means possible. Conservation via insulation it the best way to keep the heat produced. tony del plato
