With this application, it can not only ensure the volume of high temperature hot water, but also ensure the
water flow rate of heat pump system. But the total cost will be higher than other two applications due to the
cost the plate heat exchanger.
For all these three applications, it is recommended to add a manual mixture valve between city water inlet
and water tank sanitary hot water outlet. This can maximize the utilization of hot water in the tank and also
ensures its temperature won
'
t be too high to burn people.
If the structure of the tank permits, it is suggested to use a manual 4-way mixture valve in sanitary hot water
system as shown below. This can further improve the utilization of hot water in the tank
.
