摘要： Provided is a gas water heater. The gas water heater includes a pre-mixer, a combustor having a combustion chamber in communication with a premixing chamber, a condensate water assembly configured to receive and discharge condensate water, and an apparatus for controlling the gas water heater. The pre-mixer includes a premixing chamber and an air intake fan that is configured to supply air to the combustion chamber. The air intake fan is disposed in the premixing chamber. The method includes: acquiring an intake air pressure threshold; acquiring an air intake pressure value of the air intake fan; and controlling, in response to determining based on the air intake pressure value and the intake air pressure threshold that a water seal of the condensate water assembly is at risk of being blown away, the gas water heater to stop operation.

摘要： A tank assembly for a heating device and the heating device are provided. The tank assembly includes: a tank body including a first side plate assembly and a second side plate assembly, a main heat exchange pipe assembly including first heat exchange pipes, a condensation pipe assembly including second heat exchange pipes, and a heat exchange fin assembly. First water boxes are defined by the first side plate assembly, and second water boxes are defined by the second side plate assembly. Every two of the first heat exchange pipes are formed as a reciprocating heat exchange group. Each reciprocating heat exchange group is in communication with one of the first water boxes and two of the second water boxes to form a series water passageway.

摘要： A water tank assembly and a heating device are provided. The water tank assembly has a tank body, a main heat exchange pipe assembly and a condenser pipe assembly, and a heat exchange fin assembly. The tank body has a smoke inlet and a smoke outlet. The main heat exchange pipe assembly and the condenser pipe assembly are disposed in the tank body. The main heat exchange pipe assembly has a layer of heat exchange pipes closest to the smoke inlet as a first layer of heat exchange pipes. The heat exchange pipes of the first layer are in communication with each other to form a series of water passageway. The main heat exchange pipe assembly and the condenser pipe assembly at least partially pass through the heat exchange fin assembly.

摘要： A premixing device for a water heater and the water heater having the same are provided. The premixing device for the water heater has a housing and a turning plate. A first airflow passage, a second airflow passage, a first gas passage and a second gas passage are formed in the housing. The turning plate is rotatably disposed on the housing to adjust an opening degree of the first gas passage and an opening degree of the first airflow passage. An air guide hole directly opposite to the first airflow passage is formed on the turning plate.
