The following diagrams show how are pellet stove and a pellet boiler works to heat the house. Summarize information by selecting and reporting the main features, and making comparisons when relevant.

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.
