I have an old Fisher 'papa bear' wood stove about 25 years old. It heats my house really well except it goes through wood like there is no tomorrow. It will burn up a 10" log 28" long in 2 hours! I have 50 acres of woods and I am thinking it may take it all. Seriously, I saw at Patio Hearth Home and Garden Store a catalytic combustor advertised for Fisher wood stoves. Says burn times increase up to 50% while you can receive up to twice the heat from your old fisher. (I emailed asking if it is UL listed.) Anyone know about this? Could it be for real? If that could bring new life to my fisher while I cut less wood it would truly be a 'Godsend.' But I don't want to waste $118. to find out. Thanks in advance!
