This study was carried out to investigate of the combustion characteristics for the waste edible-oil and heavy oil on hot air heater. There was highly reduction in energy cost using by the hot air heater. The hot air heater to study with duct connector type, and the motor output was 2.2kW. The experimental factors for performance test, fan speed ranged from 1700 rpm to 1800rpm, and SFC, efficiency, exhaust gas emissions, and noise were measured. The results obtained were as follows; efficiency were increased to 87% at the heavy oil and was decreased to 79% on the waste edible-oil. The fuel consumption was decreased to 25L/h at the heavy oil and CO2 emissions was decreased in the case of the heavy oil
