Howdy All! I been promising pictures of the new "engine room" once finished so here they are. This is a Woodchuck 2900 furnace and a Goodman 3 1/2 ton heat pump with electric backup. Letting the heat pump do it's thing on warmer days (above 30 or so) and firing up the Woodchuck if its going to get cold. Running the Woodchuck right now. It went down to zero last night and it's up to 10 outside now and holding 74 inside. Let me know what ya think. It took a lot to figure out how to make the damper work right. Now that I have that one figured out I'm thinking of trying to find a bigger one to replace the manual damper on the wood burner.
