I bought an old 1200sqft farm house last year. The old kent fire tile was shot so I installed and englander stove last fall. I burned from November to mid March. The stove is in an uninsulated basement. I believe through rough calculations that it cut my propane bill in half. But I still paid roughly $130-150/mo with one really cold month where it jumped to $250. I'm trying to figure out if a furnace could be justified for the cost of installing one. This is my first house and I'm not sure if what I'm paying is ridiculous or not. How's the performance of a properly installed one with forced air heat?
