Description
Technical field
The present invention relates to a kind of novel zero cold water gas heaters.
Background technique
After a shutdown, forced-ventilated mechanism can continue working a period of time to water heater, the then (burning of the burner inside water heater
Heat exchange module) it can cool down rapidly, the heat exchanger tube (heat exchange linkage section) coiled on it also follows cooling, water heater restarting
Afterwards, heat exchanger tube (heat exchange linkage section) cooled down, the cold water temperature that is directly inputted from water supply connector it is relatively low, burner (burning
Heat exchange module) restarting after, it is very short with the heat-exchange time of heat exchanger tube, when water heater being caused to restart, be easy to appear hot water
The hot water quenching phenomenon of device just section output, midway downtime is longer, and hot water quenching phenomenon becomes apparent from, it is difficult in zero cold water combustion gas
