Heat-pump technology



Modern heat-pump technologies make saving energy costs in residential houses possible. Today, highly efficient systems make renewable energies available for private households via heat pumps, ventilation systems with heat recovery and solar systems all year round. All systems absorb energy from the environment and supply heat for heating and water heating. The system works efficiently which has been proven in long lasting field tests.

A heat pump can save up to 50% of heating costs in comparison to a normal heating system. Having such a saving potential means a short payback period of only few years. In the light of rising costs for fossil fuels, heat-pump systems guarantee a unique safety in private energy supply.

Normally, heat is given off by a single energy source, for example a flame which has a higher temperature than the ambient air. A carrier medium, in most cases water, flows around the energy source and absorbs heat because of the large temperature gradient. The heat is transferred from higher to lower temperatures. This energy absorbed from the boiler’s flame transports water as the carrier medium to the heating device. The operational principle of the heat-pump technology works quite similar. However, it uses the ambient heat instead of a boiler as energy source.

Since the ambient temperature is not very high, the energy absorbing carrier medium has to be colder to create a temperature gradient. Because of that water is not used as carrier medium but as a refrigerant fluid. It operates in the same way as a fridge.





A simple operating principle



Prinzip der Wärmepumpe

  1. Cooled liquid refrigerant is transported to the heat exchanger (evaporator)

    The fluid absorbs energy from the ambient air because of the temperature gradient and the refrigerant vaporises

  2. The compressor pressurizes the gaseous refrigerant

    The pressure causes increasing temperature

  3. A second heat exchanger (condenser) transports the heat to the heating system, the refrigerant returns to its fluid state

  4. The high pressure of the refrigerant is lowered on the discharge side



Power of the environment



The environment offers plenty of energy. Not until -273 °C (-459.4°F) it loses its entire energy. A heat pump can gather this energy which can be used for heating or water heating. Such a heat pump system is economically reasonable. Generating heat even works at temperatures of -20 °C (-4 °F), so in most cases nature presents you with half of a year’s heating costs.

The use of renewable energies is not only an economic aspect. Reasonable handling of resources becomes an important future task. It already pays for itself: Investing in renewable energy saves the environment and you benefit from loan programs.
