The P43 will burn any grade of pellet at maximum efficiency and still keep your home at your desired temperature. Not only can the P43 burn pellets with optimal efficiency and cleanliness, it does it automatically. The P43 automatically lights its own fire and burns at the correct output to maintain the desired room temperature. When no heat is required, the P43 will shut-down and reignite when the demand for heat returns. Just fill the hopper with pellets and set the desired temperature. The P43 will do the rest except for ash removal, which will be needed after approximately one ton of pellets has been consumed.
