Hello; I am typically driving 80km( 50 mile) back and forth from work return trip and thus I am generally full on normal summer days and when I return , my battery is empty depending on weather. Now that winter is coming and I am in Canada , so temperature has started dropping here , so now I need to put heating in equation. I have also noted that heating quality is much better when engine is on. I have following questions: 1) If I turn ON climate control remotely , Do I need to set temperature to 72 deg f before I turn off my car at night? 2) Since I have to start engine any way , is it o k to start engine as soon as I get in , so that there is no load on battery for heating in event when I forgot to turn on climate control? 2) After I get good temperature is it o k to use the car like how we used to use the car in summer time by turning A/C off and get air circulation ON internally when possible? 3) what is your best way to heat the car using engine or Battery or combination in my scenario? Any thoughts in this regards is appreciated, Thanks In advance.
