Expert opinion

« Quick B3 water heater: performance and durability for hot water on board »

The Quick B3 20-litre water heater is a reliable solution for supplying hot water on board. Its main advantage lies in its hybrid heating system: it uses residual engine energy via a heat exchanger to produce hot water while sailing, supplemented by a 500 W electric element when docked or at anchor. This versatility ensures continuous comfort without relying on a single energy source.

The design features a 316L AISI stainless steel tank, offering high resistance to corrosive marine environments and ensuring longevity. The closed-cell polyurethane insulation is a key feature for maintaining hot water temperature over long periods, reducing energy consumption. Its cylindrical shape simplifies integration, allowing installation on a flat surface.
