OVER 30 YEARS EXPERIENCE FROM GERMANY
Stiebel Eltron is Germany’s market leader in heat pump technology. Tried and
tested technology for over 30 years to give real energy, environmental and
money savings. Over 30,000 heat pumps are produced each year in the most modern
production factory in Germany.
Above: Heat pump manufacturing in the 70’s followed by todays modern test area.
Co-efficiency of performance
High COP...results in less energy use.
Comparison with competitors
More hot water delivery, more savings.

A SIMPLE PRINCIPLE AS YET UNBEATEN
HOW A HEAT PUMP WORKS
The principle is very similar to the
operation of a refrigerator, but only
in reverse.
The heat pump system contains a fan
that forces air through an evaporator (1).
The evaporator contains very cold
liquid refrigerant. The heat in the air
that passes through this evaporator is
absorbed by the refrigerant.
Low - pressure,
Low - temperature vapour
Low - pressure,
Low - temperature liquid
High - pressure,
High - temperature vapour
High - pressure,
High Temperature liquid
The now warm gaseous refrigerant is then circulated in the system via a
compressor(2). As it goes through the compressor its pressure rises and the
temperature increases further. From here it travels to the condenser(3), where
the heat from what is now a super hot refrigerant is transferred to the water
supply tank.The cooled down refrigerant then goes through an expansion valve(4),
which reduces its pressure cooling it further and the cycle starts again.
The Payback
The beauty of this technology is that the amount of
electrical energy required to operate the heat transfer
process is far less than the energy used by a conventional
electric element. For example 25° C air temperature,
70% humidity and 45° C rise of water temperature, the fan
and compressor consume 1kW of electricity to generate
4kW of heat to the water cylinder (COP).
The energy use is approx 25% of conventional electric
hot water cylinders, saving you 75% off your energy bill,
higher air temperatures means more savings. With the
predicted increase in energy costs and the cutting of
Greenhouse Gas emissions the 300Ee makes real sense
