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.
Given the complexity of the image, the above description may not be entirely accurate.

the diagrams illustrate the components of a wood pellet stove and a wood pellet boiler, and how they are used to heat a house.
The wood pellets are initially loaded into the fuel hopper while a wood pellet stove is in use. The pellets enter the combustion chamber where they are burned after passing through the fuel feed. The ashes fall into the ash pan below as they burn. The heated air rises and is directed toward the combustion fan. The fan blows it into the surrounding space. Through the exhaust duct, there flows fire smoke.
When using a pellet boiler, the pellets are also put into a hopper. They move into the furnace from there, where they are burned. The smoke elevates in the smoke stack, while the ashes are collected in the ash container. Moving inside the furnace, cold water is heated by the burning pellets. Each room in the house is heated by the warm water as it flows into the radiators. The stove heats with hot air; meanwhile, the boiler heats with water, which is the main distinction between the two methods.
