Household gas heaters have advantages such as high efficiency, safety, and environmental protection. Compared with electric heaters, gas heaters have higher energy utilization efficiency and can save energy costs. In addition, gas heaters also have better environmental performance because the greenhouse gases such as carbon dioxide produced by gas combustion are much less than those produced by coal or fuel combustion.

Household gas heaters generally consist of burners, heat exchangers, fans, control systems, etc. The working principle is that gas mixes with air and burns in the burner, producing high-temperature flue gas. This high-temperature flue gas exchanges heat with water or heat transfer oil through a heat exchanger, heating the water or heat transfer oil.
