Harnessing nature’s energy
Our environment is full of energy, even at sub-zero temperatures there is plenty of energy available.
Heat pumps use conventional refrigeration technology to extract
the sun’s energy stored in the environment and raise it to a temperature
suitable for heating purposes.This principle works even in the middle of
winter at temperatures as low as -25°C.
One system for all types of heat sources
Dimplex heat pumps offer you three different future-proof heat sources: outside air, the ground or water.
Air source heat pumps utilise the outside air as their energy source. Heat pumps can even extract heating energy from the outside air at temperatures as low as -25°C·
Ground source heat pumps extract heat from the earth all year round via ground heat collectors buried beneath the ground.
Water to water heat pumps extract thermal energy from
underground water. If the supply is readily available and the quality is
sufficient, water is the most effective heat source.
Trusted technology
A heat pump heating system consists of 3 components: the heat source,
the heat pump itself and a heat distribution and storage system.
Heat pumps are able to produce more energy than they consume by using the conventional refrigeration cycle to absorb heat from the environment and raise it to a suitable level for heating.
75% of the energy is taken from the environment i.e the air or ground
and transfered to the heat pump.
25% of the energy is sourced from the national grid in the normal way of
supplying your electricity. This is used to operate the heat pump but
with very low consumption
The energy from the air or ground is transfered to the refrigerant
inside the heat pumps evaporator. This causes the temperature of the
refrigerant to rise and change state from liquid to gas.
The refrigerant gas is then compressed, using an electrically driven
compressor, reducing its volume but causing its temperature to rise
significantly.
A heat exchanger (condenser) then extracts the heat energy from the hot
refrigerant to heat water for central heating, underfloor heating or
domestic hot water.
After giving up its heat energy the refrigerant turns back into a liquid
and is able to absorb energy from the environment, allowing the cycle to
begin again.
Using nature’s energy efficiently
Heat pumps are among the most efficient heating and hot water systems available today. Approximately 75% of the energy needed for heating comes from the environment. This means that for every 1kWh of electricity used to power the heat pump compressor, between 3 and 4 kWh of heating energy are produced, giving the heat pump an efficiency of 300-400% or higher.
The heat pump’s “efficiency” is known as it’s “Coefficient of Performance” (CoP). This is simply a ratio between the proportion of the total energy supplied that can be extracted from the environment and the amount supplied by electricity to run the heat pump compressor. The higher the CoP, the more “free” environmental energy the heat pump is using!
