The Heat Pump - Economic Heat from the Environment


They use the heat energy of the environment for heating living spaces: heat pumps. A favorable alternative to classic heating systems.

In short: heat pumps absorb heat energy from their environment (eg water or air) and transport it to another environment to heat it. Even a refrigerator operates on this principle, here the energy is transferred from the refrigerator to the outside environment to keep the air and the food inside the cabinet cold. A heat pump heater usually uses the heat from the ground to heat it up.

Building a heat pump

A heat pump usually consists of three circuits. Using a special liquid they extract the heat energy from the environment. The liquid is then compressed in the second cycle by compression, whereby it further heats up. The heated liquid then releases the stored energy into the environment to be heated in the third cycle and then flows back to absorb new heat.

Since the heat energy is extracted from the environment and not generated by the combustion of a substance, only operating costs are incurred for electricity. The compressor needs it. Especially with a heat pump heating, this results in great cost advantages in contrast to classic incinerators.

Future developments

In Sweden, nine out of ten homeowners are already using ground-source heat pump heating systems. So it happens that there are now even so-called "fuel-free communities" that do without fossil fuels for heating completely. In Switzerland, a similar development can be seen in about one third of all newly built single-family homes. As conventional fuels continue to increase in price, heat pump heating is the more cost-effective solution in the long term, as the money saved can quickly recoup the cost of a heat pump.
