I really don't want to turn on the heater just yet. Its been staying 64-67 in here. But I fired it up to 68 yesterday just to make sure its working ok so I am ready when it does get cold in here. Its a new unit, but so is my water heater and I had a gas leak in only 3 months after it was installed, which was the plumbers fault, no the unit, but still, who expects that.
