10 Water heaters
10.1 General
Use: Heating boat cabins, bridges, consumption water heating.
System accessories depending on the size, equipment and function. See the parts catalog.
10.2 Method of operation
A water/glycol mixture is pumped through the heating system by a circulation pump, where it is
heated. Then it flows through the initial pipes of the heating circuit to the various heat exchangers
(e.g. heating elements, radiators, blower heat exchangers) or a warm water boiler can be
connected.
Fuel supply: through a separate metering pump independently from the fuel tank.
Power supply (fan, electronics, etc.): from the boat battery.
Combustion circuit: separate from the heating circuit. Independent combustion air intake. Exhaust
removal through exhaust pipes including silencers to the outside.
Interior temperature regulation: by thermostat. Heating system always keeps hot water temperature
constant. The result is independent adjustment of the heating capacity according to the heat
requirement of the ship.
Motorboat example: 1) Water heating; 2) Circulation pump; 3) Heating element, radiators;
4) Blower heat exchanger; 5) Boiler; 6) separate metering pump; 7) Fuel tank; 8) Exhaust pipe
