Just like catamarans these days, a lot's changed in wood and pellet stove technology. Granted, those old stoves weren't the most efficient and did tend to pollute excessively. Today's models burn pretty darned clean and are capable of keeping an entire house pretty toasty.
Sorry about the stove digression. It's just that looking out my window at 5 below at mid-day keeps the chilly weather on the mind. Y'all enjoy the warmth down in the southern climes.
