Add-on Wood Furnace | Summer's Heat | Englander Stoves This is what I’m looking at. It caught my eye at my local Lowe’s the other day. I think it’s a pretty sharp looking furnace. I already have a hot air wood furnace but I’m looking to upgrade. My current unit burns a boat load of wood and has very short burn times. Anyone familiar with this new furnace I’m looking at? Pros, cons? I’m going back today to look it over better.
