Pellet stoves can heat homes, apartments and condominiums at an efficiency rate of 75%-85%. The fuel is composed of reprocessed wood and plant materials that are slowly released through a hopper system. Some units offer multi-fuel alternatives that also burn nutshells, corn kernels or small wood chips.
Typical costs:
Freestanding pellet stoves cost about $1,100-$4,000, depending on efficiency levels[1] , style details, size and style of hopper (holding 35-130 pounds of fuel), and type of ignition. Pellets are fed into the hopper every one to three days, from either the top or bottom of the unit. Top-fed systems are more likely to be clogged with ash, so a higher grade of fuel is recommended. Bottom-fed units may use a less expensive fuel, but they may be less efficient. Do-It-Yourselfers may install metal venting pipe straight up through the roof or horizontally through the wall, according to manufacturers' directions and local ordinances. The Hearth, Patio and Barbecue Association suggests hiring a certified professional to install, obtain building permits and ensure all safety requirements are met. Installation costs about $250-$600 in labor, depending on location and specific site requirements, while materials cost about $200-$300 for a short horizontal vent run through a wall or $600-$800 and up for a roof vent, depending on the area, type and length of vent.
Pellet stove inserts cost $1,500-$3,000, depending on size and style details. The units slip into existing fireplace openings and utilize the chimney system for the venting pipe, so no additional openings need to be cut. For example the Harman P35I[2] inserts typically cost about $3,000 and includes a 180-degree bay viewing window and a burn time of up to 65 hours. All pellet stoves require electricity and may be either plugged in or hard-wired by a licensed electrical contractor.
Window-mount units cost $1,300-$2,250 and installation is similar to window air conditioning units. For example, United States Stove Company Window Model 2400 Pellet heater[3] costs about $1,500-$2,250 and plugs into a regular household outlet. The exhaust is expelled through the back of the unit, so no venting is required, making it a possible Do-It-Yourself project. Due to emission levels, this type of ventless unit is not approved for use in all states.
Aside from the actual hopper-fed heating unit, additional services and features vary by model. Some may include a battery backup, installation or free delivery.
Additional costs:
To install a stove unit, a DIYer will need to purchase the venting materials at about $200-$800, depending on vent length and direction, along with roof sealants at $6-$10 per tube.
Pellets[4] cost about $3- $8 per 40-pound bag or $120-$275 per ton, depending on choice of premium or standard grade and location where purchased. One ton of pellets is equivalent to about 1.5 cords of firewood. The Pellet Fuels Institute[5] educates consumers about the different types of wood pellet fuel.
Pellet stoves must rest on a non-combustible hearth pad, which can cost$40 -$300 or more, depending on material and design. Decorative stove touches include $100 or more for brass trim kits, depending on size of unit and amount of trim, and $70-$170 for a set of false logs. Ignition systems vary by units and may use a starter gel at $6-$10 that is lighted with a match, a self-starting button, a thermostat or a remote control at $160-$190.
Pellet stoves burn cleanly and create little or none of the flammable residue creosote that often coats the insides of fireplaces and chimney flues. However, regular cleaning is necessary as about a cup of ash is generated per 40-pound bag. Daily or weekly cleaning with a metal ash vacuum at $120-$240 is recommended. A vent brush[6] costs about $15-$70, and annual checks by a certified chimney sweep are recommended.
A back-up power supply[7] costs about $150-$500, depending on size and style, and runs the fans and hopper when the electricity goes out.

Our house came with a pellet stove. We were unhappy to discover it requires power to operate, as it has a fan that makes the pellets burn . If the power went out our backup heater would not heat...
