Heat pumps utilise renewable energy from the ground,
sun, groundwater and air. This means they lower
the consumption of fossil fuels, conserve valuable
resources and reduce CO emissions that damage

the environment.
Another benefit is that many of the heat pumps from
Viessmann feature active and natural cooling functions.
Alongside their classic application as heat generators
on cold days, they can also create a pleasantly cool
ambience in summer.
Our extensive range offers the ideal heat pump to suit
every requirement – individually matched to structural
and geological conditions, as well as heat demand.
Running a heat pump with power generated on site by
a photovoltaic system is particularly environmentally
responsible and cost effective.
Ideal for new build and modernisation: Viessmann
heat pumps can be operated with solar thermal or
photovoltaic systems, and in conjunction with an
existing oil or gas heating system. This allows every
building and property owner to realise their individual
ideas.

Heat pumps from Viessmann offer tailor-made
solutions for heating and cooling, as well as a
convenient hot water supply, for both new build
and modernisation projects.

HEAT PUMPS
Brine/water heat pumps use
the ground as their primary
energy source, either with
geothermal collectors or
geothermal probes.

energy sources that are practically free and can
be used to run a heat pump system efficiently.
