I have one with my forced fan oscillating heater plugged in and it works beautifully. The temp is set to 40. It seems to raise my electric bill by maybe 5 dollars a month if we have a lot of nights in the low 30's to upper 20's. Also collect 2 ltr soda bottles, paint them black and fill them with water (passive solar heating). It's astonishing how well those work!
