Heat Pumps

Heat Pump technology involves equipment which transfers energy (heat) from one location (an open space) to another (a heat sink). Heat pump technology uses the refrigeration process (is applied by transferring) and transfers low temperature energy to a refrigeration loop, compresses the gases (heat) to a high temperature and transfers this heat to the hot water and heating distribution system (device called a heat sink). No matter how large or small the building, we will have a heat pump system to meet your needs. Eartheat offer a range of Heat Pumps including:

Air Source Heat Pumps

Air Source Heat Pumps do not incur any civil ground works cost for the installation and laying of pipe. The cost of civil ground works can be significant using alternative ground source systems, this is not a consideration that is required for Air Source Heat Pumps. This makes this option a significant advantage over Ground Source versions.

Ground Source Heat Pumps

Ground Source Heat Pumps can be designed and incorporated into a project in a variety of ways dependant on geographical, topographical and geological conditions to collect heat from horizontal or vertical loop systems including sufficiently sized bodies of water.

Borehole Heat Pumps

If you do not have the room to install a ground loop, then a Borehole (Vertical Loop) system can be used. Boreholes are drilled to a pre-determined depth (Geothermal boreholes are typically 50 to100m deep and approximately 150mm in diameter).

Water Source Heat Pumps

Water source heat pumps work by absorbing the heat from the sun which is stored in bodies of water such as lakes or rivers. A system of flexible pipes containing fluid is laid in water. The fluid absorbs heat from the surrounding water as it passes through the pipe and carries it straight into your home.

How Do Heat Pumps Work?

1Brine* circulates in a collector coil and draws low
temperature energy from the ground, air, bedrock or
water.

2At the heat exchanger (evaporator) the tepid brine in
the collector coil meets the ice-cold refrigerant** in
the heat pump which is then heated a few degrees
and converted to a gas.

3In the compressor, the pressure is increased thereby
raising the temperature of the refrigereant. The heat
that is then generated is transferred via a heat
exchanger (condenser) to your home’s heating
system.

4Via the condenser, the refrigerant releases the heat to
the heating system of your home. In connection with
this the refrigerant is cooled.

5The refrigerant circulates and an expansion valve
lowers the pressure and the refrigerant becomes cold
again. The process begins again when the refrigerant
meets the tepid brine from the collector coil.

* The brine is a mixture that cannot freeze,
for example alcohol or glycol.
** Modern environmentally sound refrigerants are
used e.g. hydrocarbons and carbon dioxide.
