So, have you burned it yet? One advantage of the Dw is the blower option, when you need to recover room temp fast or get heated air moving in a less open layout. The Keystone is more of a radiant heater, the Dw adds convection and blower capability. I'd rather not have blower noise, of course...wife needs quiet(!) In winter we have about 1300 ft to heat - house is old but ok for insulation and tightness
