I was hoping that I would heat the basement and get a fair amount of the heat to seep up through the floor to the rooms above, minimizing my need for using our propane furnace. I've been operating it about a month and have noticed that the general feeling in the house is a little warmer, (basement a lot hotter), but I would like to find a way to retain more of the heat in the floor (basement ceiling). Anything out there on the market already or has anyone rigged something up to retain heat so the floor remains warm? It just seems like I have to run the stove hotter in order to see any appreciable difference upstairs.
I went though some similar issues, and I agree you shuold have bought a stoker boiler/furnace. I'm saying this b/c I have a Harman Magnum stoker and I've been struggling to get the heat upstairs and not have my basement be 100F.
Short answer: Cut a vent/s into the floow and run duct from your stove to those registers. LsFarm pointed out that you should have a register running to the inlet of your blower motor so that this creates a complete loop of air circulation. I did evertthing but but the return loop and my basement is MUCH cooler and my house is MUCH warmer and I'm burning LESS coal YEAH BABY!!!
