The hot water inlet connector 110 receives hot water generated by the gas water heater. The hot water flows back to the gas water heater after passing through the heating heat exchanger 210, water tank 300, and return water connector 120. The hot water inlet connector 110 can be a joint, valve body, or connector to facilitate pipe connection. The fan 220 blows air into the heating heat exchanger 210, thereby blowing out the air heated by the heating heat exchanger 210 to form warm air for the user's heating needs.

[0033] The outer surface of the water tank 300 is provided with a heat preservation layer, which can be heat preservation cotton or other heat preservation materials, which can reduce the heat loss of hot water in the water tank 300, so that the water in the water tank 300 can maintain a relatively high temperature. Alternatively, the water tank 300 has a heater inside for heating the water in the water tank 300, which can heat the water in the water tank 300 in real time or on a timer, so that the water in the water tank 300 can maintain a relatively high temperature.
