Compact convenience
Design and installation are completely
problem-free with air | water heat
pumps from stiebel eltron. the
practical compact design houses all
components and safety equipment
together inside a single enclosure.
that reduces the overall volume and
saves valuable space. the air | water
heat pump uses the outside air down
to a temperature of –20 °C as a heat
source. between –5 °C and –20 °C, a
small electric booster heater switches
itself on, subject to demand. in its
different versions, this produces
sufficient heat for small to large
houses with a living space of up to
500 m².
