I've been using an old ashley imperial for the last 5 years to heat my 2200 sq ft home. Works great lots of heat paid 220 bucks for it. How much wood would i save switching over to a englander 30? I've got 6 acres of oak and have never cut a live tree yet, just using dead and fallen trees so far. Plenty of wood on hand. Just wondering if I'd get better burn times and use less wood with new stove?
