OSO Hotwater

OSO HOTWATER is a family-owned business established in 1932, specializing in the manufacturing of stainless steel water heaters. The company operates as a leading producer in Europe, utilizing a highly robotized manufacturing plant to ensure product consistency and quality.

Its core business revolves around designing and producing water heaters with a focus on energy efficiency and durability. The products incorporate class-leading insulation, such as VACUUM panels, which can reduce heat loss significantly and save consumers on energy costs. The heaters are constructed from premium materials like titanium-alloyed stainless steel and Incoloy 825 to provide high corrosion resistance and longevity, particularly in hard water conditions.

The company serves both residential and commercial markets, supplying heaters to major heat producers in the alternative energy sector. Its product line includes tank-in-tank units designed for heat pumps and integrated systems that combine heating and storage. The business model is based on the sale of these high-performance water heating units, which are engineered for faster heating, higher temperature output, and increased capacity within a standard unit size.
