Gas water heater is a type of water heater that uses gas as the main energy material, and the high-temperature heat generated by gas combustion is transferred to the cold water flowing through the heat exchanger to achieve the purpose of preparing hot water. Gas fired water heaters are the mainstream water heaters that once dominated the water heater market. Their advantages are that they are ready to use, do not need to wait, and occupy a small area, which can save a lot of space for comrades living in cramped homes.
