The Air/Water version of the Vitocal 350 achieves outputs of up to 20kW, even when the outside temperature is below zero

This model is perfectly suited to new build and to the modernisation of heating systems with radiators in existing buildings.

A particular benefit of this heat pump is that it exploits the energy source very easily. Collectors do not need to be buried and bore holes do not need to be drilled. It can be installed indoors or out and draws energy from the ambient air without the need for extensive installation work. Even when the outside temperature is below zero, it can achieve flow temperatures of 65°C.

Flexible installation options inside or outside your property

The Vitocal 350-A also leaves you to choose between an internal or external installation. Benefits of an external installation: You save valuable living and utility space.
