All in one air source household heat pump is a very smart products.
It combines heat pump and water tank together, top is heat pump, bottom is water tank.
The heat exchanging process is:
Top part, air-refrigeant
Bottom part, refrgerant-water.
So in the water tank, there is a pipe coil. In the pipe coil, it runs refrigerant, water is in internal wall of tank.
The pipe coil is outside internal wall of water tank, and is put in the wave of the internal wall. SPRSUN all in one heat pump supplied with safe valve (combined with non-return valve), the valves should be installed at the cold water inlet.
Users just need connect tap water to the cold water inlet of heat pump, and connect hot water pipe to the hot water outlet of heat pump.

Advantages:
This type water tank advantage is: Copper pipe in tank will not be corroded by life hot water.
