WITA HE+: Circulation pump for heating and solar systems

The WITA HE+ series circulation pumps were specifically developed for use in heating and solar systems and impress with their high energy efficiency. With energy savings of up to 80% compared to conventional circulation pumps, they offer a modern and environmentally friendly solution for your home. Thanks to innovative technology, the hydraulic performance remains almost at the level of standard models, while you benefit from significantly reduced operating costs.

Efficient performance for a wide range of requirements

The circulation pump adapts flexibly to your requirements. With a power consumption of only 3 to 41 watts and a maximum delivery head of 6 meters, it is ideally suited for a variety of applications. Its flow rate of up to 3,500 liters per hour easily covers even larger heating and solar systems. Despite its high flow rate, the pump operates efficiently, making it a reliable and economical choice for your system.

Thanks to its electronic control system, the pump dynamically adapts to current requirements. This not only reduces energy consumption but also ensures quiet and trouble-free operation.

Robust materials for durability

The WITA HE+ is made of high-quality materials that guarantee a long service life and reliable operation. The pump housing, made of cataphoresis-coated gray cast iron, protects against corrosion and increases durability. The impeller, made of technopolymer, combines lightness and stability to ensure optimal performance.

With a maximum permissible operating pressure of 10 bar and a temperature range of +5 °C to 110 °C, the pump can be safely used in a wide variety of systems. IP42 protection and Class F insulation complete the robust design and ensure additional protection and safety during operation.

Easy installation and compact design

Thanks to its standardized dimensions, the WITA HE+ is easy to install. With a length of 180 mm and a 1 ½" connection thread (approx. 53 mm wrench size), the pump fits perfectly into most heating and solar systems. Its compact design also allows for easy installation in confined spaces.

An additional advantage: The pump does not require separate motor protection because it is short-circuit proof. This simplifies installation and minimizes maintenance costs.

Environmentally friendly and certified

The WITA HE+ bears the CE mark and therefore meets all relevant European safety and quality standards. Thanks to its high energy efficiency, the pump actively contributes to environmental protection by reducing energy consumption and thus CO₂ emissions. This makes it not only a cost-saving but also an environmentally friendly choice.

Conclusion: High-performance pump for heating and solar

The WITA HE+ circulation pump is the ideal choice for anyone seeking an efficient, high-performance, and environmentally friendly solution. Its combination of energy savings, flexible performance, and robust materials makes it the perfect complement to heating and solar systems. Featuring state-of-the-art technology and easy installation, the WITA HE+ offers excellent value for money and ensures the sustainable optimization of your heating and solar technology.
