The unit
The hot water heat pump is one of the most economical systems to heat the water for family domestic
use.
Using free renewable energy from the air, the unit is highly efficient with low running costs. Its efficiency
can be up to 3 ~ 4 times more than con entional gas boilers or electrical heaters.
•Waste Heat recovery
Units can be installed near the kitchen, in the boiler-room or the garage, basically in e ery room
which has a large number of waste-heat so that the unit has the higher energy efficiency e en
with ery low outside temperatures during the winter.
•Hot water and dehumidification
Units can be placed in the laundry room or clothing room. When it produces hot water it lowers
the temperature and dehumidifies the room as well. The ad antages can be experienced
particularly in the humid season.
•Stora e room coolin
Units can be placed in the storage room as the low temperature keeps the food fresh.
•Hot water and fresh air ventilation
Units can be placed in the garage, gym, basement etc. When it produces hot water, it cools the
room and supplies fresh air.
•Compatible with different ener y sources
Units can be compatible with solar panels, external heat pumps, boilers or other different
energy sources.
•Ecolo ical and Economical Heatin
Units are the most efficient and economical alternati e to both fossil fuel boilers and heating
systems.
By making use of the renewable source in the air, it consumes much less energy without direct
CO2 emission.
•Compact desi n
Units are especially designed for offering sanitary hot water for family use. It’s extremely
compact structure and elegant design are suitable for indoor installation.
•Multiple Functions
The special design of the air inlet and outlet makes the unit suitable for arious ways of
