I have been reading the posts for the small cabin. We live in Oregon and the coldest average temp. in the winter is in the low 30's-high 20's. We are insulating our garage and turning it into a pottery studio and we have free hardwood (madrone) on our property. The area size we will be heating is all one room and only about 435 sq. feet. We will not be needing a hearth since the floor itself is cement. Oregon stoves must be EPA certified. So far we are looking at the Quadra Fire millennimm2100, the Morso 1410 & 1440, and the Buck model 18. We are familiar with heating with wood-just never in such a small place! Right now there is a great sale on the Buck stove so that one is looking pretty good to us and the reviews we ave read on the company seem to be the most favorable so far. On the expensive end we have been considering in the Quadra fire Millennium 2100. We would welcome your advice and any suggestions that you might have. Also, is it true that if we build a small fire in a bigger box that it ruins all the efficiency stats? Thanks! Chris W
