Band 6+: The following diagrams show a pellet stove and a pellet boiler to work to heat a house. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

THE FOLLOWING DIAGRAM SHOWS HOW A COMPONENT OF A WOOD PELLET STOVE AND A WOOD PELLET BOILER, AND HOW THEY ARE USED TO HEAT A HOUSE.

THE COMPONENTS OF A PELLET STOVE AND A PELLET BOILER ARE WOODEN PELLETS. THE FINISHED PRODUCT OF A PELLET STOVE IS HOT AIR WHILE THE END PRODUCT OF PELLET BOILER IS HOT WATER.

THE WOOD PELLETS ARE INITIALLY STACKED INTO THE FUEL HOPPER WHILE A WOOD PELLET STOVE IS IN USE. THE PELLETS GO INTO THE COMBUSTION CHAMBER WHERE THEY ARE BE ON FIRE AFTER PASSING THROUGH THE FUEL FEED. THE ASHES GO DOWN INTO THE ASH PAN BELOW AS THEY BURN. THE HEATED AIR GOES UP AND IS DIRECTED INTO THE COMBUSTION FAN. THE FAN BLOWS INTO THE SURROUNDING SPACE. THE FIRE SMOKE FLOWS THROUGH THE EXHAUST DUCT.

WHEN UTILIZING A PELLET BOILER, THE PELLETS ARE ALSO INSERTED INTO A HOPPER. THEY MOVE INTO THE FURNACE FROM THERE, WHERE THEY ARE BURNED. THE SMOKE RAISE UP IN THE SMOKE STACK WHILE THE ASHES ARE GATHERED IN THE ASH BOX. GOING INSIDE THE FURNACE, COLD WATER IS WARMED UP BY THE BURNING PALLETS. THE WARM WATER HEATED EACH ROOM IN THE HOUSE AS IT GO ALONG INTO THE RADIATORS. THE STOVE HEATS WITH HOT AIR MEANWHILE THE TWO DISTINCTION BETWEEN THE TWO METHODS IS THE BOILER HEATS WITH WATER.
