I am fulltiming in California, but make it a point to use as little propane I buy outside the space rent price as possible. My main small propane use is for the stovetop burners. This is very easy in 50 amp service spaces, but I can do it in 30 amp service spaces, too. My first level of heating comes from the electric fireplace heater which pulls about 10 amps. My bigger electric portable heater pulls about 12 amps. That keeps interior temperature 60 degrees and above, which I am comfortable with, with some warm clothes or a thermal blanket throw. I have an electric blanket for the bed, and it just pulls an amp or so. If on 50 amps, I leave the water heater on electric all the time, otherwise I just heat water during the day on electric when air heating demands are at a minimum. When on 30 amps I monitor the electrical usage closely with the Progressive EMS remote readout in the control panel. Running the microwave takes special attention, and usually turning of heaters off temporarily while microwaving(on 30 amp service). I very rarely run the furnace. I have not refilled one of my 30 gallon propane tanks since early October. They still haven't switched over yet. I have been through a week or so of sub freezing overnight temperatures around New Years.
