i start at 40 degrees with the timer set to kick on one hour before i need to start. roughly i move up the timer one hour for every ten degrees it drops. most of the time i don't change it until we are regularly below 20 for a morning low, then i set it to three hours. figure if i can't afford 50 cents for the electricity to help the truck fire like a summer day, then i can't afford the fuel to drive it. alot of people complain about the 1000 watt heater spinning their meter. it's super easy to figure being 1000 watt heater, for every hour its on, it cost whatever you pay per kilowatt hour. my last bill was 18 cents per kilowatt hour. cheap and easy on the truck so it's a no brainer to me.
