Osculati 50.290.51 - ATI Rectangular Boat Boiler 20L – 230V 1250W Marine Water Heater
The Osculati 50.290.51 ATI Rectangular Boat Boiler is a compact marine water heater designed for onboard hot water systems where installation space is limited. The boiler operates in bivalent mode using either the integrated heat exchanger or the electric heating element rated at 1250 W / 230 V.
Version A is equipped with a porcelain glass-lined tank, aluminium outer casing, and enameled heat exchanger. Enhanced thermal insulation in expanded polyurethane maintains water temperature for up to 123 hours while improving energy efficiency.
The oversized heat exchanger delivers practical heating performance superior to many larger-capacity standard systems. The rectangular form factor allows easier installation in confined technical compartments onboard.
