1. Biomass pellet furnace uses biomass energy as fuel, such as sawdust, straw, chaff, etc. Low fuel price and high utilization rate. The air energy water heater uses the heat energy in the air and needs a small amount of electricity to ensure the operation of the compressor, which is three to four times that of the traditional electric heating equipment, and the operating cost is high.

2. The fuel of the biomass pellet furnace is solid particles, which is convenient for transportation and storage, simple in combustion process and low in maintenance cost. The air energy water heater needs regular cleaning and maintenance, including replacing the filter screen and maintaining the compressor. The maintenance cost is high, so the biological particle furnace saves money.
