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 two diagrams illustrate how a house is heated with pellet stove and pellet boiler.
Overall, pellet stove and pellet boiler use wood pellets to heat a house, the former combusts wood pellets and produces hot air, the letter on the other hand combusts wood pallets to heat cold water.
To begin with, pellet stove has fuel hopper in which wood pellets are put and can be sent through fuel feed which supplies combustion chamber with pellets. In combustion chamber pellets will be burnt thereby producing hot air which goes to combustion fan and heats the room.
When it comes to pellet boiler it has the same fuel hopper and metal container in which wood pellets placed. Cold water enters to the furnace with the help of metal tubes and then inside, it will be boiled. Then, hot water will circulate through pipes which can go from living room to bedroom while heating the surrounding air. Both of them provided with smoke stack and ash pan to eliminate waste products.
