Principle Description

This series hot water tank can be combined to use with fresh water pressure tank on board, that is to use fresh water in fresh water pressure tank to replenish this tank, and then heated by electric or steam heating elements for usage of entire vessel.

System Piping

1 Cold water inlet: connected to the outlet of fresh water pressure tank to inject water into tank so as to keep the cold water pressure in tank between 0.36 and 0.38MPa.

2 Hot water outlet: connected to the hot water general pipe on board for use.

3 Water return interface: connected to hot water return pipe to make the hot water heat circularly.

4 The water outlet of safety valve：to discharge the pressure water. It is connected to bilge.

5 Discharging outlet: to empty all of the water in tank. It is connected to bilge.

6  Steam inlet: connected to the outlet of temperature regulating valve.

7 Steam outlet: connected to condensate water piping.
