I struggled with my stove early on, but with the damper closed It's a pleasure to generate heat from an arm full of logs for a big chunk of the day. Hard to put words to it. At first I tried to quantify my cost of the stove, plus splitter, plus time and effort to have wood delivered or to process what I get here and there for free from my property or elsewhere.
If you just try to match dollar for dollar against burning say oil or dare I say natural gas if you have it available, you will probably at best break even.
But go get a quote for a new furnace plus install.
Also consider that wood heat provides an emergency backup both short term and long term. All you need is some wood piled up in the yard for a few years
