VITOCAL 300-G
With the Vitocal 300-G, you can utilise sustainable heat stored underground or in ground
water. This heat pump was designed for utmost compactness, so it takes up remarkably
little space: Inside the casing of the BWC/WWC models, the circulation pumps for the
brine circuit and the heating circuit, as well as the 3-way diverter valve, are already
integrated.
The Vitocal 300-G ground source heat pump
is specifically designed for detached houses.
It utilises heat that's right on your doorstep.
What's more, you call the shots, selecting
the output from 6.2 to 117.8 kW, making it
both efficient and effective. So your central
and DHW heating needs will be reliably and
conveniently covered.
Heat from the ground or groundwater
You can choose how you get heat from the
ground with the ground source version. This
is done either via a geothermal probe or
via a geothermal collector laid at a depth of
approx. 1.5 m. In both cases, the heat pump
covers the entire energy demand, even on
colder days. Subject to the location of your
house, it may also be possible to utilise the
latent heat in groundwater. For this, the
Vitocal 300-G is simply converted to operate
as a water/water heat pump – and delivers the
highest COP in this operating mode.
Tightly packed performance
The Vitocal 300-G (type BWC/WWC) proves
its worth through its particularly compact
design. It contains everything Circulation
pumps for brine circuit and heating circuit
including a safety assembly with safety valve,
pressure gauge and air vent valve fitted as
standard. This clever integration minimises
the space required. An electric booster heater
is available as an accessory.
Greater heat demand?
No problem for the Vitocal 300-G
For buildings with a very high heat demand,
the two-stage Vitocal 300-G based on the
master/slave principle is the right choice. It
achieves a heating output of 12.4 to 117.8 kW.
Here, you also have the choice between the
groundwater or the ground as the heat source.
Vitocal 300-G are
certified in accordance
with the EHPA heat
pump quality seal and
NF-PAC.
