Abstract

The invention discloses a gas-fired water heating device, a gas-fired water heating system, a gas-fired water heater and a water heating device. The gas-fired water heating device comprises a heat exchanger provided with a water inlet and a water outlet, a burning device, a water pump and a control device; the burning device is used for heating water in the heat exchanger, the burning device has a first working mode with a first output power range and a second working mode with a second output power range, and the first output power range is smaller than 4 KW; the water pump is communicated with the heat exchanger, and the control device is connected with the burning device and the water pump; the gas-fired water heating device has a preheating circulation mode which meets the conditions that the control device controls the water pump to drive the water in the heat exchanger to flow and controls the burning device to be in the first working mode. By means of the gas-fired water heating device, the starting frequency of the burning device and the water pump can be reduced, sound made by the gas-fired water heating device can be reduced, and the temperature of outflow water can be kept stable.

Description

technical field [0001] The invention relates to the technical field of hot water, in particular to a gas water heating device, a gas water heating system, a gas water heater and a water heating device. Background technique [0002] Existing water heaters (gas water heaters, heating furnaces and electric water heaters) often form circulation lines through return pipes to avoid waste and inconvenience for users. The water in the circulation pipeline is heated by the hot water device, so that when the user uses hot water, he does not need to discharge the normal temperature water or low temperature water in the pipeline between the hot water device and the water terminal, and can use hot water at any time. . [0003] In the prior art, when the hot water device is circulating, due to the high heating power of the hot water device, the water temperature of the water in the circulation pipeline often reaches or exceeds the set water outlet temperature quickly. The heating device...
