Pellet Stoves

With skyrocketing oil prices, some homeowners are turning to wood pellet stoves to provide supplemental (or in some cases, primary) heat. Pellet stoves look similar to wood stoves or fireplace inserts, but the similarities end there. Inside, they are very sophisticated combustion appliances. 
Most pellet stoves produce a small fire that, concentrated in the center of the unit, burns hot. If you like the look of a fire, it's important to find a unit with a good flame pattern and large viewing glass. For some pellet stoves, you can get ceramic logs that help disperse the flames and give the fire a more traditional look.
The motors, of course, require electricity (some have battery backup units). A stove will need a nearby 110-volt outlet. If you live where power outages are frequent, you may want to have a gas-powered generator on hand so that you can use the stove if the power goes out.
Pellet stoves are measured in heat output range, also called heating capacity. Most have a rating of 8,000 to 90,000 Btus (British thermal units) per hour. To choose the right sized pellet stove, work with a knowledgeable dealer who can take into account the many variables and factors that will determine the best choice.
A variety of styles are available in both freestanding stoves and fireplace inserts. Some manufacturers also make pellet-fueled furnaces and boilers that are designed to take the place of—or supplement—conventional forced-air heating systems.
