Have been thinking used but the tax credit and all I might as well go new. It's an older single wide and I'm wondering if something like an Englander, rated at 1500 sq ft is to big. Can you keep then on a low enough setting to keep the fire going? Had a pellet stove in our house, Envirofire, I think, a few years back and it would sometimes stall on lowest feed rate. Any suggestions for a stove?
