DesignHome - Interior / Fireplaces look inviting in a home but are highly inefficient when it comes to heating. The solution is a wood (or pellet) burning stove installed directly into the fireplace as illustrated in this picture. It looks much better than an insert, and if well-matched to the fireplace, imparts ambience as well as warmth to the room.
QuadraFire Mt. Vernon Pellet Insert This extra-large unit comes standard with comfort-quiet blowers to heat up to 3,800 square feet. Like other pellet models, it runs on biofuels, including wood pellets, corn, sunflower seeds, and wheat. Other features include a firepot auto-clean system, programmable thermostat wall control, and auto lighting and operation programs.
