VITOCAL 222-G
Vitocal 242-G, the compact brine/water heat pump with the Vitocal 242-G DHW cylinder,
with connection to a solar thermal system as an option.
Complete and extremely compact – the
compact Vitocal 242-G and Vitocal 222-G
heat pumps are fully equipped with all
components required for DHW and central
heating. With heating outputs of between
5.9 and 10.0 kW, they are designed for use in
detached houses and flow temperatures of
up to 60 °C mean they can also be used with
conventional radiators.
The Vitocal 242-G and Vitocal 222-G are
attractively priced alternatives to the
compact appliances of the 300 series. With
the Compliant scroll compressor and a
thermostatically controlled expansion valve,
they achieve coefficients of performance
of up to 4.3 (to EN 14511 with brine 0 °C/
water 35 °C). For the heating and brine circuit,
three-stage adjustable circulation pumps are
integrated into the appliances.
Operating the appliances is extremely easy
thanks to the new Vitotronic control unit.
Vitocal 242-G is fully prepared for
solar operation
Vitocal 242-G is fully prepared for the
