Quick Stainless Steel Nautic Boiler 1200W Square with Heat Exchanger 25L

The Quick Square 25 L Boiler (BXS series) is a compact, high-efficiency marine water heater combining electric heating and heat-exchanger capabilities. Designed with a square profile, it’s ideal for tight installation spaces on board, offering flexibility without compromising performance.

Its welded AISI 316 stainless steel tank resists corrosion and ensures long service life, while the built-in heat exchanger (coiled 316 stainless tubing, more than 3 m in length) allows engine coolant to warm water while underway, saving power.

With a 1,200 W heating element, it delivers reliable hot water whether tied to shore power or running on generator output - perfect for Irish cruising or live-aboard applications where energy flexibility and resilience are essential.
