If you're of a certain age and grew up in the New York City area, you probably remember watching the Yule Log on WPIX on Christmas Day. Channel 11 used to show a fireplace aglow for hours on end, a goofy yet—if not literally—warming looping log.

Some of us used to look for the spot where the loop ended and started again—perhaps not the most exciting thing to do on a holiday but if the bowl games were boring or the weather too nasty to go outside, this detective work did provide a diversion.

While most wood- and pellet-burning stoves won't allow you to watch the burning logs, they clearly have grabbed the interest of many consumers who are looking for less expensive ways to heat their homes. If you're considering adding one of these devices to your home, read our buyer's guide and these blog posts on an innovative pellet-delivery system and the fluctuating price of fuel for these stoves.—Steven H.
