My neighbor runs a pellet stove exclusively throughout winter and it does a good job of keeping his house toasty. There are two downsides to it I don't like though. 1. There are motors that must move in order to feed those pellets into the burn chamber. If they go, you're dead in the water......which is exactly what happened to him Saturday night. Now he's stuck waiting for a new motor to arrive by mail. That problem could be offset by having a couple spare motors sitting around waiting to go, but it still doesn't solve the dilemma of reliable moving parts for long term use. My fireplace has one moving part, the flue control, and that's it. Not much that can go wrong with that! And 2. if the electricity gets cut for whatever reason, he's got himself a nice fancy 300 lb living room decoration. No power will be going to the motors, blower, control panel, etc. So now he needs a backup generator to keep it running, which kind of defeats the purpose entirely. I like the K.I.S.S. (Keep It Simple Stupid) approach to heat in the winter. Less moving parts and no electricity needed for it will always trump convenience in my view
