Viessmann, a manufacturer of high-efficiency heating and renewable energy systems, announced the launch of ducted and ductless air-to-air heat pump solutions — Vitocal 100-S and Vitocal 200-S — designed to enhance energy efficiency and comfort for both residential and light commercial applications.
The Vitocal 100-S single-zone air-to-air ductless heat pump systems are designed for reliable comfort, even in extreme climates. Suitable for a wide range of installations, including both new builds and retrofits, the Vitocal 100-S offers ultra-quiet operation and high-efficiency inverter technology for increased energy savings. Minimal installation requirements make ductless heat pumps ideal for applications with limited space and where ductwork does not exist.
The Vitocal 100-S single-zone air-to-air ducted heat pump system combines the advantages of traditional ducted heating and cooling with the efficiency and flexibility of ductless inverter technology, providing a compact, cost-effective and complete solution for whole-home comfort. This system offers quiet operation, a compact design and the enhanced efficiency of inverter technology while also supporting the reuse of existing refrigerant lines, ductwork, thermostats, fan coils and furnaces. Suitable for upgrading an existing ducted HVAC system, constructing a new home, or expanding an existing one, the Vitocal 100-S ducted heat pump solution is a versatile and efficient choice.
The Vitocal 200-S multi-zone, air-to-air ductless heat pump system is designed for customizable comfort across multiple spaces, delivering reliable heating and cooling with advanced inverter-driven technology for optimized performance and energy saving efficiencies. Homeowners can mix and match each outdoor unit with up to five indoor units, bringing tailored comfort to individual rooms or the entire home. With increased capacity and energy efficiency, this model is can be used in residential and light commercial applications, or larger projects in more challenging climates. It also offers ease of use with an intuitive control system, ensuring long-term reliability and comfort for both residential and commercial properties.
“Our mission is to drive innovation that supports the ever-changing demands of the industry,” said Ben Jewell, head of P=product and engineer for North America at Viessmann. “These new products reflect our commitment to providing advanced, reliable, and energy-efficient solutions for contractors and homeowners. By offering superior performance, simplified installation, and long-term reliability, we continue to set new standards in heating and cooling technology.”
