Vitocal 151

The Vitocal 151‑A is a compact, high‑efficiency air‑to‑water heat pump designed for modernisation and new‑build projects alike. With a flow temperature of up to 70 °C and the use of the natural refrigerant R290 (with a GWP of only 0.02), it delivers reliable heating, cooling and hot water while helping lower running costs and environmental impact.

Featuring an integrated 190‑litre domestic hot water cylinder and the latest Viessmann control platform, the system is easy to install, monitor and maintain. With excellent performance even in colder outdoor conditions (down to ‑10 °C) and a footprint engineered for compact spaces, the Vitocal 151‑A brings high‑end renewable technology into practical everyday use for installers, architects and specifiers.
