Osculati 50.389.55 - ATI Boat Boiler B 30L – 230V 1250W Stainless Steel Marine Water Heater
The Osculati 50.389.55 ATI Boat Boiler B is a premium marine water heater designed for onboard hot water systems requiring high corrosion resistance and flexible installation. The boiler operates in bivalent mode using either the integrated heat exchanger or the electric heating element rated at 1250 W / 230 V.
Version B features an AISI 316 stainless steel boiler combined with a stainless steel heat exchanger and mirror-polished aluminium external casing. Enhanced insulation in expanded polyurethane allows water temperature retention for up to 123 hours while improving energy efficiency onboard.
The oversized heat exchanger delivers practical heating performance superior to many larger-capacity standard systems. The unit also includes a front exhaust tap and supports installation on three axes, making it suitable for complex marine layouts.
