The Vitocal outdoor unit cares about looks and compactness, an asset when the location is visible. Discreet operation for the neighbours and for you alike.
The Vitocal can be paired with a boiler for a gradual transition: the heat pump does the bulk, the boiler takes over in deep cold. A gentle renovation.
The ViCare app schedules time slots, tracks consumption and adjusts the temperature remotely, with one of the most accomplished levels of connectivity on the market.
Beyond the brand, it's the efficiency, the finish and the connectivity that justify the premium positioning. The key figures for Viessmann heat pumps, sized and tuned by our teams.
Viessmann focuses on top-of-the-range air-to-water with the Vitocal range: central heating, hot water and a refined finish. We choose based on your home and your comfort requirements.

See prices & grants →When you replace your heating, you choose two things: a heat pump brand and an installer. Viessmann answers the first with a premium positioning: build quality, high efficiency and advanced connectivity. It's the choice for those who want the very best in air-to-water.
The Vitocal range aims for excellence: one of the best seasonal efficiencies, a compact and quiet outdoor unit, and a highly accomplished ViCare control. The refined finish is as visible as it is audible — an asset when the location is visible or close to the neighbours.
"Premium is also measured by what you don't hear: a quiet, well-finished heat pump fades into the background for years on end.
That's where our role as installer counts. We calculate heat loss, size the right output to exploit the premium efficiency and set the heating curves. We remain your single point of contact for the warranty, maintenance and after-sales service — ViCare connectivity helps us act quickly.
A SCOP among the highest. On the best-sized Vitocal models, the seasonal efficiency aims for excellence — the exact figure depends on the model and your home.
