Water heater
The following directions do not replace the instructions provided in the
manufacturer’s manual, delivered separately.
•
The water heater, which has a capacity of 23 litres and an electrical resistor of 1200 Watts, is
installed in the room immediately above the engine and can be accessed by opening the
highest door in the side bulkhead of the engine room, from both aft cabins (see diagram at
page 66).
•
It is made of treated and glazed steel, conveniently insulated and equipped with a safety valve
and a drain tap.
Instructions
You can heat the fresh water by using:
-
the electrical resistor in the boiler, supplied by the 220 V electrical circuit;
-
the engine cooling water, that flows in the boiler through a by-pass on the engine
and a coil in the boiler.
Please follow these instructions for starting the water heater:
•
Check that the boiler is full by turning on a hot water tap.
•
Turn on the FRESH WATER PUMP switch in the 12 Vdc electrical panel or check that it is
already turned on, to enable the fresh water pump and pressurize the cold and hot fresh water
of the system.
•
Then, to heat the water by using the electric power you just need to turn on the WATER
HEATER switch in the 220 Vac electrical panel (see page 54) (To be able to use 220 V power
see the relevant chapter at page 47).
•
To heat the water by using the engine please follow these instructions:
-
Check that the valves on top of the engine, that from now on we refer to as “engine-boiler
circuit valves”, are open. These valves with their pipes link the engine cooling system to
the fresh water heating coil; unless there is something wrong with the water heater or the
circuit, they must be always open.
-
Start the yacht propulsion engine and the water heater will automatically begin working
(provided that the engine-boiler circuit valves are open); normally, the water reaches a
temperature of 50°-60°C after approximately 15 minutes, with the engine running at 1500
revs.
