After burning wood for years I have switched over both our place and my fathers place to Anthracite coal. I liked burning wood but after years of cutting , stacking and cleaning up the mess in the house plus if the wood was a "bad batch" or I had to buy wood from the fore mentioned "wood salesman" I really don't think it can beat coal . In real cold weather I have to fill my coal hopper (holds 50 lbs) 1 time per day and in more mild temp (35-40F) I have to fill it every 1 1/2 days and I use ZERO propane. I forgot to mention near zero chance of a chimney fire. Here is a link if anyone is interested. http://www.nepadigital.com/bb/index.php
