Firewood Purveyor
I just sell wood, don't have an OWB, but at least 18-20 customers use them. I would say on average most will use 13-15 full cord of wood there are many varibiles involved size of home, insulation, heat exchangers used, etc. I know if I were buying an OWB, my first choice would be a Central Boiler, or Wood Master, you couldn't give me a Wood Doctor, they are a total pos from want I have seen first hand, warped cracked doors, cracked fireboxes etc. Get one with a big enough door to put wood in, Hardy's have too little of door and too little water capacity. Most customers say they get 8-10 hours between loading, the poor cuy with the wood doctor fills every 5 to 6 hours. I've had folks with CB's say twice in twenty four hours. I don't think most customers realized how much work maintaining an OWB would be when they purchased theirs. several of the customers wished they had just used a quality stove like a Pacific Energy, Jotul, etc or a furnace like a Yukon Eagle, they didn't realize they needed to maintain the waters ph level/condition the water, the labor of cleaning out, how much wood they burn etc. Several have 8-10k tied up in their systems, and realize it is going to take a while to recover the cost.
