Natural hot springs in Iceland
If you put a gas under pressure (compress it), it liquefies and heats up. If you remove the
pressure, it evaporates again and extracts heat energy from its surroundings. This
principle is used by a heat pump. A type of coolant circulates in it that is alternately
compressed and expanded. In outdoor pipe coils, it absorbs heat, for example from the air
or groundwater. It then releases the heat again through radiators inside the house, at a
slightly higher temperature. Although a heat pump uses some electricity for compression,
overall it generates more heat than, for example, an electric heater with the same power
consumption. In order for it to work well, the house should be well-insulated.
Geothermal energy is the use of Earth’s heat.
Simple home systems use heat pumps to extract heat
energy from groundwater. Larger systems tap into the
heat of deep rocks. This works particularly well
in volcanically active areas, such as Iceland or New Zealand.
With solar thermal energy, solar heat is captured using
large, dark solar collectors that contain liquid-filled
pipe coils. They conduct the heat into the house,
where it is used for heating or hot water.
