Pellet stove appliances have automate as many functions as there is possible. The most significant one is the fuel delivery. When the user sets the heat setting an auger or similar feed device will regulate the delivery of pellet fuel from the hopper to the fire (Figure 2).

By having automatic fuel delivery of the pellet fuel the user does not need attend to the frequent loading while at the same time providing clean burns and the desired comfort level. To get the desired combusion air is automated or with a slight manual adjustment.

In most pellet stove designs, a fan delivers air to the fire and will blow exhaust by-products out of a vent pipe, which is a smaller and cheaper version of a chimmey (Figure 3).


In most pellet stoves systems, a fan delivers heat to the home by blowing air through heat exchangers in the stove and out into the home. Heating efficiency is greatly enhanced by removing the heat from the appliance before it can exit the system.
