We are new to this board and are trying our best to not rely so much on modern things.. I love my electric don't get me wrong, but I sure hate that bill!! Especially when in December we paid $350.. we have an old farm house, 2200 sq ft. and have 5 bedrooms. We have 2 heatpumps, and when it's cold they work hard.. we really would like to use some wood heat verses gas of any sort. I am just always worring about fires though, and then there is the cost, we are so tight right now it isn't funny, believe me that $350 bill killed us!!! Is it safe to buy one used? with the layout of our home we really would have to get like 2 small ones, one at each end of the home. What are good brands, types? I know nothing about them, but have seen them recently in a local paper for sale, and they are all used which would fit the budget better.
