So living in Canada we get extreme winters with temperatures as low as -40 celcius so it takes a while for the battery to warm up and this of course uses more range. I am due to start construction of a new house and have the option to heat the garage using hydronic underfloor heating. Of course this comes at a cost approx. $7000 plus the annual energy usage. Normally I do not heat my garage at all as I just use it to park my car. Do you think it would be an overkill to heat the garage during winter or is it just not worth it?
