A heater is an energy conversion device that inputs energy into the heater in the form of chemical energy from fuel, electrical energy, and thermal energy from high-temperature flue gas. After being converted by the heater, it outputs warm air, hot air, and high-temperature air with a certain amount of thermal energy. A heater consists of two main parts: a combustion system and a fan. The combustion system generates enormous heat, which is then blown out by the fan.

When using a household gas heater, it is important to pay attention to safety issues. Firstly, it is necessary to ensure that the gas pipeline is firmly connected to prevent air leakage. Secondly, it is necessary to regularly inspect the burner and heat exchanger for damage or blockage to ensure the normal operation of the heater. In addition, good ventilation should be maintained during use to avoid the generation of harmful gases such as carbon monoxide due to incomplete combustion caused by hypoxia.
