Problems solved by technology

For places where the water point is far from the water heater, especially where two or more water points are installed, the phenomenon of wasting water resources is more serious, and the parts inside the water heater and the external circulation pipes will freeze and crack due to low temperature
This kind of water heater is extremely inconvenient for users to use, especially when using hot water every time, a large amount of water resources will be wasted

Abstract

The invention discloses a water heater water supply system with a rear circulating pump and a control method. The water heater water supply system comprises a shell, a heat exchanger and a combustor for heating the heat exchanger are arranged in the shell, a cold water inlet and a hot water outlet which communicate with the heat exchanger are formed in the shell, a circulating pump is arranged ona pipeline enabling a water outlet of the heat exchanger to communicate with the hot water outlet, and a controller which is electrically connected to the circulating pump and the combustor is furtherarranged in the shell. The water heater water supply system has the advantages that the circulating pump is arranged at the hot water outlet end, so that installed parts are reduced, the structure issimple, the energy consumption is low, and the cost is saved.

Description

【Technical field】 [0001] The invention relates to the technical field of household gas instant water heaters, in particular to a water heater water supply system and a control method with a post-installed circulation pump. 【Background technique】 [0002] For a gas instant water heater installed in ordinary households, it takes a long time to wait for the water supply valve to be ignited and burned to reach the required outlet water temperature. During this time, a large amount of accumulated water in the pipe needs to be released. For water points that are far away from the water heater, especially where two or more water points are installed, the phenomenon of wasting water resources is even more serious, and parts in the water heater and external circulation pipes will freeze and crack due to low temperature. This water heater is extremely inconvenient for users to use, especially when hot water is used every time, a large amount of water resources will be wasted. [000...
