Heat pumps for outdoor installation:
Maximum efficiency with minimum energy consumption
The new Vitocal 100-A air/water heat pumps cover most applications in new build and modernisation projects. With outputs between 6 and 16 kW, the specifications for convenient heat supply and domestic hot water preparation can be met.
Gold protects against corrosion and ensures long service life
In comparison to conventional heat exchangers, the Vitocal 100-A has a gold-plated exchanger. Long-term tests with saline liquids have shown that no visible corrosion has occurred. This guarantees the user a long service life.
Eco-friendly refrigerant R32


Low-cost space saving buffer solutions
The Vitocal 100-A offers different low-cost solutions combining an external mounted buffer store, which is ideal for space saving applications, with a separate DHW cylinder. Alternatively, a combi buffer is available comprising a buffer and DHW cylinder in one.
Comfortable wireless control with touchscreen and plain text display
