I've been running my Englander for a week or two now in several different configs. I have a brand new 2000 sq ft ranch with an unfinished basement. It has blown in R-23 in the walls of the finished living floor, and R-19 insulation tucked in the floor joists (basement ceiling). The best setup I have found is the one pictured below. I have about 2/3 of the grill covered on the front of the stove with a "bonnet" that is mostly hard piped into the cold air return duct work of my Heat Pump Air handler. The walls eat up most of the heat that doesn't get sucked into the cold air return bonnet I have setup. I keep the air handler fan in the manual position to keep the air moving from the stove to all my upstair rooms.My goal has been to have the HP and the auxiliary elements inside the air handler run as little as possible obviously. There has been enough heat escape around the bonnet to keep the basement @ 55-60 ish degrees which seems to be just right for my 3 labs that we keep down there. For the most part with the stove on 5 heat I can keep the living quarters about 67-68 degrees which is an ideal temp for the family. No one is complaining about being too cold or too hot. With the temps outside from 25-35 degrees the Heat pump does not kick on at all... EVER. Anything below that and the heat pump will bring the heat back up to 68 if it falls to 66 in the house......Now my questions are will I overheat or strangle the stove by using the bonnet on it? How much energy am I using by keeping the t-stat option "fan-on" on the heat pump 24-7? The down side is we hear the blower running all the time....not too noisy though. Should I pull down all of the R-19 that is in the floor joists? If I'm running the pellet stove 24-7 I don't see a need for the basement ceiling to be insulated. Thanks for your input guys! I've learned so much by lurking here!
