Vitocal 222-G compact brine/water heat pump

Compact, efficient and quiet heat pump: Vitocal 222-G

Compact, quiet heat pump that takes up little space – also suitable for installation close to the living space.

The Vitocal 222-G compact brine/water heat pump is fully equipped with all of the components required for DHW and central heating.

With heating output levels of between 5.8 and 10.4 kW, it is ideal for use in detached houses. Flow temperatures up to 65 °C also enable use with conventional radiators.

This heat pump is the attractively priced alternative to the compact appliance in the 300 series. With its refrigerant circuits with a fixed heating output (in three output sizes) and an electronically controlled expansion valve, it achieves a COP (coefficient of performance) of up to 4.8 to EN 14511 (5/2018) at B0/W35.

The small footprint of this heat pump makes it particularly suitable where space is at a premium – the brine circulation pump, heating circuit pump and 3-way diverter valve are already integrated inside the compact casing.

For easy handling and installation of the Vitocal 222-G, the new refrigerant circuit module can be simply removed from the heat pump and transported separately if required, thanks to plug-in hydraulic and electrical connectors. With the flexible connection concept, the heat pump can also be quickly matched to the installation situation on site.

The casing of the compact appliance completely protects the refrigeration module/hydraulic compartment from the outside environment and, in conjunction with the three-dimensional anti-vibration mounts, minimises operating noise. These compact heat pumps are some of the quietest in their category, as they generate a sound power level of only 46 dB(A) (B0/W55).

The Viessmann Vitocal 222-G is Heat Pump KEYMARK certified.
