We had our propane tank filled in Jan before the price hike. When we heard of that, we went to using 2 eden pure heaters, each will heat 1000 square feet, (the Jan propane bill for 197 gals was $491) Then the price doubled. We just got our first electric bill doing this, and it was $241. We have only used 10% of our propane fill, for cooking and hot water, so I know we will make it till the price drops. I figure a $241 electric bill is better then a $1000 propane bill any day, and the two heaters keep it plenty warm in here. Average between 69-72 degrees depending on how cold it is, they are also completely safe, no carbon monoxide to worry about or fire hazard and do not get hot to the touch.
