6.1.2 Hot fresh water system

Water is drawn from the tank by mean of pump and delivered to the water heaters to be heated.

The surge tank pump keeps the circuit under pressure continuously.
The thermostatic valves installed on the water heaters allow the setting of the hot water temperature at the taps.
In order to use hot water, it is necessary to:

• The water heater and autoclave magneto-thermal circuit breakers in the main electrical panel located in the crew quarters must be in the ON position;
• Ensure that a power supply is connected (generator or shore);
• Make sure the service battery breaker is set to ON.

The water heaters are powered at 230V AC, taken from shore or from the on board power generators. By means of a distribution manifold, the hot water is conveyed to the following utilities:

• Bathrooms;
• Galley sink;
• Bow shower;
• Stern shower.

WARNING

To activate the water heater, either activate the generator or get connected to shore mains, without forgetting to check the current amperage of the harbour you are moored into.

WARNING

Never switch on the electric resistance if the water heater is empty.
