The invention provides a heating control method and device, which are applied to a gas water heater. The gas water heater is connected with a cold water pipe and a water return pipe. The method comprises the steps: obtaining water inlet temperature of the cold water pipe and first duration when the water return temperature in the water return pipe is equal to first preset temperature after the gaswater heater executes a first heating task; obtaining the number of times of cyclic heating after the gas water heater executes the first heating task; according to the water inlet temperature, the number of times of cyclic heating, the first duration and the first preset temperature, determining circulation heating duration; and carrying out a second heating task according to the circulation heating duration, and heating the water entering the gas water heater. The method and the device are used for reducing cyclic heating duration, thereby reducing gas consumption and improving user experience.
Description
technical field [0001] The invention relates to the field of gas water heaters, in particular to a heating control method and device. Background technique [0002] At present, the gas water heater is connected to the hot water pipe and the return pipe (cold water pipe). Hot water taps, shower nozzles, etc., the hot water in the hot water pipe can also enter the gas water heater again through the return pipe, so that the gas water heater can heat the water circulation in the return pipe, and send the hot water circulation to the hot water heater that needs hot water. Faucets, shower heads, etc. [0003] In the prior art, the method for circulating heating of gas-fired water heaters includes: obtaining the return water temperature in the return water pipe. The water in the water pipe is heated, and when the return water temperature is equal to the set temperature, the heating is stopped. In each cycle heating process, the water in the return water pipe needs to be heated, a...
