HEAT PUMP OPERATING PRINCIPLE
The actual heat gain from the environment takes place in
the heat pump‘s evaporator. This is where the liquid refrig-
erant comes into play, which evaporates even in sub-zero
temperatures, thus storing the recovered energy.
The volume of the refrigerant, now in gaseous form, is then
drawn in and reduced by the compressor. When the refrig-
erant is compressed, the pressure increases signifi cantly,
thus also increasing the temperature of the refrigerant.
Within the closed circuit, the hot refrigerant fl ows on to the
liquefi er – a heat exchanger in which the recovered environ-
mental heat is transferred to the heating system.
Thanks to a cooling process, the refrigerant once again re-
turns to liquid form. After the expansion valve has caused a
reduction in pressure and temperature, the refrigerant can
once again absorb thermal energy from the environment,
and the cycle begins once again.

One system for all types of heat sources
Dimplex heat pumps offer you three different future-proof heat
sources, free of charge:
outside air, ground or ground water.
Together with the electric energy required to drive the heat
pump, the stored solar energy generates the system’s heat-
ing potential, which is transferred to a water-bearing heating
system.
Heat pumps are among the most effi cient heating and hot water
systems available today. Since about 75% of their heating energy
comes from the environment for free, they only require an addition-
al 25% in the form of electricity to produce a 100% heat output.
Air-to-water heat pumps utilise the outside air as their
energy source. Even at temperatures of up to -25°C, heat
pumps can still extract heating energy from the outside
air.
Brine-to-water heat pumps extract heat from the
ground, year-round via ground heat collectors or
borehole heat exchangers with a high heating
capacity.
Water-to-water heat pumps extract the thermal energy
from the ground water. If the supply is readily available
and the quality is suffi cient, ground water is the most ef-
fi cient source of heat. However, it is also the most sensi-
tive one.

A heat pump heating system consists of the heat source system, the heat pump itself and a heat distribution and storage system. Within
the closed circuit of the heat pump, the refrigerant is responsible for transferring and transporting the heat.
