Hot Water System 

The hot water system draws fresh water from the cold water 
System via a non-return valve to the water heaters located 
under the berth of main stateroom total capacity is 11 US 
gallons. 

The water heaters operate on AC 220 immersion heaters 
powered by the generator or the shore power. 

Hot water is distributed to the washbasins, showers, galley, 
transom shower. 

If the vessel is to be laid up or left unattended in a cold 
climate, the entire fresh water system, including the pumps 
filters and water heaters should be drained to prevent 
Damage.
