Osculati 50.389.52 - ATI Boat Boiler B 45L – 230V 1250W Stainless Steel Marine Water Heater
The Osculati 50.389.52 ATI Boat Boiler B is a high-capacity marine water heater designed for efficient onboard hot water production and long-term corrosion resistance. The unit 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 outer casing. Expanded polyurethane insulation between the tank and casing maintains water temperature for up to 123 hours while improving overall thermal efficiency.
The oversized heat exchanger provides thermal performance superior to many conventional systems with significantly larger tank capacity. The boiler includes a front exhaust tap and supports installation on three axes for flexible mounting in marine environments.
