A lot of us are going to hydronic boilers up here in Alaska. Some people are going with wood, others with pellets, but most are going with coal. By comparison with oil, oil cost roughly $4.00 a gallon, coal works out to .98 gal for comperable BTUs. My fuel bill is $1,000.00 a month to heat my house. With coal I figure I can heat it for $300.00 a month. I have looked at several brands, but the Titon II is the one I have decided to go with.
