The principle of the return pipe of the air water heater is as follows:
When installing the water return system, a set of check valves must be installed beforehand upon return. The water system is working, the cold water in the pipe (the hot water pipe) is pumped out. At this time, cold water will flow from the check valve to the cold water pipe, and the water in the cold water pipe will flow to the water. water heater, thus forming internal circulation) and heated by the water heater. The running time of the machine can be adjusted according to the length of the hot water pipe.
It is understood that domestic water return systems, also called hot water preheating circulation devices, can be applied to different types of gas water heaters, electric water heaters, solar water heaters, air water heaters, wall-mounted devices. fitted boilers, domestic underfloor heating systems, andvs.
