Hello-

I've recently purchased a home that has a guest suite addition that is
on a slab, so not on the central gas forced air HVAC. Instead they
installed one of those Amana "motel units," a through-wall electric
combined heat/AC unit, that handles the bedroom, bathroom, and
hallway. The total space involved is approx. 325 sq. feet. We live in
Minnesota where it routinely hits -20 in the winter and my guess is
that this unit will be horribly expensive to use for heat so I'm
looking for alternatives. I'd prefer a gas unit of some sort and am
open to almost anything: fireplace, free-standing stove, direct vent
wall heater, etc. Or any other ideas folks may have-- particularly if
you have experience with a specific model or kind of technology that I
can find easily in central Minnesota.

Thanks!
