Abstract:
Provided is an energy-saving indoor gas water heater, comprising: a water heater body (201), an exhaust gas pipe (202), an exhaust gas fan (203), an air intake fan (204), an air outlet (205), and an air inlet (206). The exhaust gas pipe (202), the exhaust gas fan (203), the air intake fan (204), the air outlet (205), and the air inlet (206) form an energy recovery device. The exhaust gas pipe (202) is mounted inside the water heater body (201), and the exhaust gas fan (203) extracts exhaust gas and sends the exhaust gas to the exhaust gas pipe (202). An opening is arranged on each of two sides of the water heater body (201) to form the air inlet (206) and the air outlet (205), and the air intake fan (204) is mounted next to the air inlet (206). Cold air enters from the air inlet (206) driven by the air intake fan (204), is heated while flowing through the exhaust gas pipe (202), and the heated air is discharged from the air outlet (205). The water heater of the present invention can heat indoor air in winter, and improves efficiency of energy use.
