Third reason is catalytic stoves are economical.
Catalytic stoves generally have longer burn cycles, lower stack temperatures and higher heat transfer rates than non catalytic stoves, and so the heat generated stays in your home rather than going up the chimney.
What this means is, the longer burn times and high efficiency and heat transfer rates of catalytic stoves will allow you to heat your home with less wood to burn.
You save money without sacrificing heat. It's that simple.
