About the P Series
The HeatMaster SS P-Series burns wood pellets for clean, steady, hands-off heat. Load pellets into the bin instead of splitting and stacking wood, and the furnace feeds itself.
Pair it with a hopper bottom attachment for fully automated feeding. The control system watches oxygen levels, fires the auto igniter when needed, and adjusts the air damper to keep the burn clean and efficient.
