The image contains two diagrams of heating systems: "Pellet Stove" on the left and "Pellet Boiler" on the right. The Pellet Stove diagram shows a labeled cutaway view with the following components: Exhaust Duct protruding from the rear panel, Wood Pellets being poured into the Fuel Hopper, a Combustion Fan, a Fuel Feed, a Combustion Chamber with flames and hot air, Controls, and an Ash Pan. The Pellet Boiler diagram shows a house cross-section with bedrooms on the top, a living room below, and a furnace system on the bottom right. The system consists of a Smoke Stack on top, hot water pipes leading to radiators in the rooms, a furnace with wood pellets and an ash receptacle, and cold water supply on the bottom.

The schematic of a pallet stove and a pallet boiler illustrates how work to heat a hause by use wood pellets. A pellet stove is working by hot air but a pellet boiler is working by hot water.
First of all, at the first schematic is describing how a pallet stove working. Firstly, wood pallets pour into the fuel hopper and these pallets goes to the combusition chamber passes to fuel feed hall. In the combustion chamber, wood pallets use for fire to make an hot air. Ashes from the fire fall into the ash pan. After the heating of air rise to combustion fan and go out to heat of rooms.
The second schematic of a pallet boiler works like a pallet stove but main differences are when wood pellets pour into the hopper, the cold water comes to furnace and boils there for to get hot water which is rising to radiators to heating all rooms. Therefore, steam from boiling also comes out from smoke attack.
