The most efficient furnaces deliver the best value. At 92% overall efficiency (LHV), the CleanFire 900 provides the highest efficiency of EPA Certified stick-wood burning appliances compared to outdoor appliances with a maximum output greater than 300,000 Btu/hr.* It also delivers the highest Btu rating of cord wood appliances, with a rating of 400,000 Btu/hr. CleanFire furnaces are among the top for efficiency of all stick-cord wood heating appliances certified for sale for residential heating in the USA.

Heat your space for far less money than fuel oil and propane. Owners who have scrap wood sources or cut their own basically eliminate their “fuel” costs. Energy savings allow traditional outdoor wood furnace owners to dramatically lower their heat costs.
