For comfortable living to be achieved, room temperatures should be
slightly above 20 °C. This temperature deviates only slightly from the
outside temperature during most of the year.
In contrast to heating systems that utilise a boiler, which generates tem-
peratures of several hundred degrees during the combustion process, a
heat pump generates only the temperature that is needed. In doing so, the
Aquarea air / water heat pump utilises the heat energy in the surrounding
air to heat buildings and provide hot water. In other words, the system
utilises the freely available environmental air. Electricity is needed only to
operate the compressor, electronics, pumps and to operate the additional
electric heater in the event of extremely low outside temperatures.
