Heat Pumps.

Heat pumps, driven by electric motor, used for private heating, industrial heating
of water in production processes or heat recovery, with a performance ranging
from 10 to 1,500 kW heating capacity. The mainly used refrigerant is R-134a.

Geothermal heat pumps that extract warmth needed for heating from the ground
using ground probes, collectors or similar. The advantage is that the energy
source is available year round at a relatively constant level.
Heat pumps using water from wells, rivers, lakes etc. recover the energy needed
through for each project special designed heat exchanger systems. Water in a
sufficient quantity is an efficient heat source, especially since it is usually
available on a relatively high temperature level.
Systems which can be used for heating and cooling at the same time
are interesting due to their being highly economical. That is on the condition
of there being a sufficient heat source available, such as the above
mentioned geothermal or water systems.
