Abstract
The present disclosure discloses an ignition temperature control apparatus of a gas water heater, comprising: a heat exchanger made of stainless steel; a combustion device which supplies high-temperature flue gas to the heat exchanger; a water passage communicated with the heat exchanger; a first temperature detection device provided on the heat exchanger or on the water passage; a controller, wherein if a temperature detected by the first temperature detection device is lower than or equal to a first preset temperature or a rate of decline of a temperature detected by the first temperature detection device is higher than or equal to a first preset value the controller controls the combustion device to operate in such a state that a requirement for thermal bearing capacity of the heat exchanger made of stainless steel is satisfied. The heat exchanger of the ignition temperature control apparatus of the gas water heater of the present disclosure, which is made of stainless steel, has good thermal inertia and excellent thermal insulation properties, and thus the combustion device is started for heating when the ignition temperature control apparatus of the gas water heater is in a st…
