Controller station for commercial split water heating sytem

According to the domestic system, the commercial controller station is a little complex, and different systems need their own contrller station, need special design

Normally most of the controller sets will be combined in one big box, placed on the place where available for manager to check and work, water pumps are installing together with the water tanks.

The following points must be designed for different systems:

1. Distance between the solar collectors and the water tanks, and the users.

2. How much hot water do the users need, how does the user using the hot water (how many times, how much per time, how much temperatue).

3. Are there any other energy source( such as electric heater, gas heater, etc.) as backup ?

4. How about the water quality of the users? And what about the water pressure ?

5. How do they loading the cold water ? From the city water supplying system or from a water tower ?

6. How about the solar energy ( solar radiation efficiency) in the markets ?

7. Other information, more date more better to design the system.
