Description
Technical field
The utility model relates to a kind of water-heater system more particularly to a kind of zero cold water gas heaters with water circulating pump
System belongs to field of water heaters.
Background technique
Since the gas heater of family is typically mounted on living balcony, and bath water is in bathroom, from bathroom to kitchen
Fang Youyi sections of longer pipelines, generally have between 10-30 meters.Therefore, when user has a bath, the cold water having in pipeline must first be put
Can just there be hot water outflow out, and to release many cold water to come out hot water, prolonged wait is not said, wastes very
More water.Special weather turns cool when turn cold, and hot water does not come out for a long time.Therefore, it solves first put one before using hot water every time
Duan Lengshui becomes the generally existing use problem of gas heater industry.
In the prior art, the inside of gas heater is equipped with a small-sized water circulating pump, and user gets ahead before with hot water
Start water pump before to water heater, water pump can be extracted into the cold water in the water pipe in user family water heater and here be heated, so
It is transported to again in the water pipe in user family afterwards, after waiting the cold water in service pipes to be all heated into hot water, user is in bathroom or kitchen
Tap is opened in room, hot water flows out soon.But start to heating from water pump and complete to need the regular hour, and
And therefore some gas energies of consumption and electric power energy if starting circulatory function is not convenient enough, cause to want with hot water Shi Bufang
Just starting or error starting will reduce user experience and more consumption gas energies and electric power energy.
Utility model content
In order to solve problem above, the purpose of the utility model is to provide a kind of zero cold water gas and hot water with water circulating pump
