Energy is available throughout our environment, even when the air temperature drops below freezing there are still plentiful resources of energy.
Today's refrigeration technology is used via Heat Pumps to extract energy which lies stored all around us from the suns daily energy output, and is used to raise temperatures for heating. Even in the coldest months this technology works.
Proven Technology to Trust
Dimplex heat pumps can be viewed as three separate components. The heat pump, taking heat from the source and the storage and distribution system. By using refrigeration technology the pump is able to produce much more energy than it consumes.
A large quantity of low grade energy absorbed from the environment is transferred to the refrigerant inside the heat pump (evaporator). This causes the temperature of the refrigerant to rise (even at sub zero temperatures) causing it to change from a liquid to a gaseous state.
2.
The refrigerant is then compressed, using an electrically driven compressor, reducing its volume but causing its temperature to rise significantly.
3.
A heat exchanger (condenser) then extracts the heat from the refrigerant to heat water for central heating, under floor heating or domestic hot water.
4.
After giving up its heat energy the refrigerant turns back into a liquid and after passing through an expansion valve can once again absorb energy from the environment, allowing the cycle to begin again.
Efficient use of the energy surrounding us
In today's world, one of the most efficient ways of heating your environment and water is the heat pump. About 75% of your heating energy that is needed can come from the environment. In essence, for every 1kwh of used to run the heat pump you gain between 3kwh and 4kwh. Very high efficiency indeed.
The heat pump’s “efficiency” is know 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
