This thread has been seriously derailed. The OP asked if there were non-propane options including diesel.

There are, indeed, diesel stove and furnace options. Since they are less common, and found mostly in the marine trades, you'll find they're much more expensive. Instead, why not go all electric? The options are readily available, not much more than standard equipment, easily retrofit. Just seems to me like a better all around alternative.
