Oh yeah, been there and done that. During my DoD years spent a few years in Va. and had a heat pump. Heck it was useless below around 35F. There was the magic "Emergency Heat" button on the thermostat. That button kicked in the electric heating elements. Heck that was over 30 maybe 35 years ago and I think it was VEPCO (Virginia Electric Power COmpany) that was Public Enemy #1. Thank God the place had a fireplace and we had a chainsaw.I have no natural gas in the mountains where I live. We are on a heat pump, and of course, it's almost useless at 15 degrees F. I'm forced to use portable kerosene heaters, which isn't all that bad. Actually, I enjoy the sitting in the warm glow when I'm reading or browsing. In the last month, all the kerosene I was able to get was full of water! This played havoc on my heating equipment, but I was finally able to get some good fuel, and just in time too. When my money gets better, I'm thinking about replacing the heat pump with a propane heater and having a tank put out.
