We have a Harman P61 (great stove) that we installed new in Oct. After almost 3 months of steady use, we finally figured out how to heat our house with the stove! I guess we're a little slow.....we trialed many different settings and air movement options (hanging fans in doorways, running our ceiling fan, running furnace fan, etc., etc., etc. Because our stove sits on one end of our house we were having trouble getting the warm air to the farthest reaches. My husband set the fan on the floor in the room adjacent to the room with the stove and turned it so the cool floor air was blowing into the stove room and voila! Our entire downstairs is now at a steady temp. using stove temp. We couldn't be happier! Just thought I'd share in case others are having a similar problem.
