Klaus utilizes state-of-the-art machinery, molds, and welding equipment in the production of hot water tanks. Our stainless steel water storage tanks provide safe and hygienic hot water supply.

The boiler body and heat exchanger coil are fully made of stainless steel and are available in single or double coil options. The lower coil connects to the solar energy system, while the upper coil connects to the hot water boiler. During periods of low sunlight, the upper coil ensures uninterrupted domestic hot water heating.

High-quality insulation minimizes heat loss. Boilers up to 500 liters feature polyurethane insulation, while models above 500 liters use removable soft foam insulation. All products carry an energy efficiency label and undergo a 13-bar leak test.

With Klaus boilers, you can trust in a solution that combines hygiene, reliability, and energy efficiency for your hot water needs.
