US gal multiply by 264 For the least amount of wood handling the wood with the highest heat content is most desirable An open fireplace can actually refrigerate a house because it sucks in so much cold air that is only partially used for combustion A carefully designed fireplace makes use of perhaps 10 1596 of the heat available most still going up the flue The well constructed potbellies get perhaps 20 25 and the automatic draft regulated tightly sealed wood heaters get perhaps 50 Notice that the percentages efficiency goes up as the combustion process becomes more and more controlled The roaring fire is a complete waste of fuel The best situation is one where the combustion chamber is gas tight This allows a controlled fire that toasts the wood and puts the right quantity of wood gas in the right place and at the right temperature for optional combustion and heat transfer The NEWMAC WOOD FURNACE toasts the wood to charcoal and the charcoal burns to dust leaving a minute amount of residue From the above heat values it can be seen that a cord of Hickory wood is equivalent to 661 92 89 06 liter worth of oil over twice as much as you would pay for a cord of wood Without taking into account all the free wood that is available EFFICIENT WOOD HEATING cuts your heating costs in half 21 FIG 10 WIRING DIAGRAM BELT DRIVE WIRING DIAGRAM BELT DRIVE NEWMAD WAO E OR GAD BELT DRIVE DIL FURNACE GAO A
