Amazingly easy yet totally convincing
Heat pumps cleverly utilise
environmental energy from the
ground, the groundwater or the air
and convert this energy into useful
heat. that is good for the environment
and for your bank balance.
Heat out of "thin air"
the heat pump technology is, in
principle, comparable to that of a
refrigerator. Heat is extracted from a
medium and is passed to another.
the wwK 300 utilises the ambient air
from boiler or cellar rooms. For this,
a heat exchanger extracts the latent
heat and transfers this to the water in
a cylinder. this provides a detached
house round the clock with 100 to
300 litres of hot water. DHw heating
doesn't come much more affordable.
saves up to 75%
the wwK 300 recovers up to 75%
free energy from the ambient air.
that lowers energy costs for DHw
heating and reduces environmental
contamination.
A solar thermal system on your
roof makes the whole even better.
Consequently, not only the energy in
the ambient air but also that provided
by solar rays is utilised. that is
environmental protection that helps
you to save day by day.
Convincing performance
suitable for several draw-off points in
domestic and commercial properties.
in heat pump mode, the appliance
delivers hot water up to 55 °C. the
heating output can be boosted to
65 °C at the push of a button. the
installation location can be freely
selected. At ambient temperatures
from +6 °C to +35 °C, the heat pump
operation is guaranteed. the CFC-free
thermal insulation reduces heat losses
to a minimum.
