Most square footage heating claims are very general..
Agreed. But people want to have a general reference point. Of course everyone's situation will be different; some slightly, some wildly.
Jaffadog, if you can, get below and install a cold air return duct from the end of the bedroom hallway or the masterbedroom back to the other end of the house, and put a floor grill adjacent to the air inlet to the circulation fan for the Hitzer 503.. this will pull air from the other end of the house and provide the all-important circulation loop for the heated air off the HItzer.. Or install the duct and install it's own fan pulling cool air from far end of the house and force it into the heated room next to the Hizer.. moving the cold air as well as the hot air works several times better than trying to just move the hot aor alone,, there has to be circulation,
Absolutely. That cold air return is essential to getting the warm air to the far end of the house. The cold air has to be displaced by the warm air, and the cold air needs to go somewhere or the circulation just won't happen. The eventual plan is to put a grate in the floor in the far corner (i.e., coldest part) of the master bedroom and duct it to one or two grates in the floor near the fireplace. Only laziness (and lack of funds from the stove purchase) are keeping me from doing just that right now.
My main goal, at least for this winter, is to put a serious dent in my oil use, but not necessarily try and heat the entire house with the Hitzer. Even if I can heat half the house with the Hitzer and the other half with the baseboard hot water, I stand to save $3,000+. If it's more than that, great. But even if the master bedroom zone is cool, the other half of the house should be toasty-to-tolerable. In time, and with the proper ductwork, it's certainly possible to cut my oil use even further and save even more. But after spending about $1,000 more for the Hitzer than we had originally budgeted for, just finding the money for the coal will be a challenge. That extra $1,000 was originally earmarked for 3 tons of nut....
Remember, the proper term should be "home-moaner," not "homeowner."
