The development of Viessmann Climate Solutions heat pumps since 1978

Highly efficient and innovative heat pumps are a central component of our climate solutions. We launched the first air source and brine/water heat pumps back in the late 1970s. Ever since, we have continuously worked on our heat pumps, making them more and more efficient and reliable from generation to generation. With our latest generation, the Vitocal 250-A and 252-A, we have developed a high-quality air-to-water heat pump in a monobloc design. It is particularly suitable for modernization and achieves a flow temperature of up to 70 °C.
