How did we keep warm before EPA? I rented 2 homes as a teen way back in the 70's with wood heat. One was a cabin with a firebox Old wood stove it didn't even have brick linings. The next an Old 2 storey farmhouse with a big woodstove in the basement and floor grids on the main and upper floors to allow the heat through them. Both the cabin and the house stayed warm for 12 hours and both had been there with their original heaters for over 30 years. Before we moved in. The soapstone heater has been sitting hooked up for quite a while and has been used as plant stand. We are just looking for tips to see if our installation idea is safe.
