Heat pump

Save heating costs with geothermal energy

Geothermal energy has many advantages. Fossil fuels are expensive and natural sources are of course limited. Gas and oil prices are rising in the long term. The use of geothermal energy is a real alternative to constantly scarcer energy resources.

Conventional heating is outdated. Heat pumps reduce your heating costs by comparison to oil or gas by up to 75%. Geothermal heating derives approx. 75% of your heating from the environment free of charge. At present there is no cheaper means for heating since three quarters of the energy needed comes from the environment! Thus the required investment pays for itself very quickly and the heating costs will remain payable in the future also.

You do not need the energy of a 2000°C flame for a hot water temperature of 37°C. The combustion technique is no longer in keeping with the period – and far too expensive. Heat pumps are the safest and most dependable of heating systems. They use a free source of energy stored in our environment and make you independent of oil and gas prices. Thus heat pumps guarantee the lowest running costs not only  today but also in the future. This is also true of cooling with a combined heat pump - you will find the costs are a lot lower than those of conventional air conditioning.

Advantages of a heat pump installation

  • Combined heating and cooling for your house
  • Usually with integrated heating of hot water
  • Chimney not required
  • Emissions and chimney sweeping are superfluous
  • No fuel prepayment and fuel storage
  • Independent of oil and gas prices
  • Relief for the environment with no CO emissions.

This how it works:

Part 1 – Heat source facility – Geothermal drilling
Using underground pipe circuits (borehole heat exchangers), the heat pump can draw a brine fluid up through the soil. This brine fluid absorbs the earth temperature and thus transports the heat (0-13 °C) to the heat pump.

Part 2 – Heat pump
From the brine fluid (0-13°C) warmth is then extracted by means of a heat exchanger. The temperature level of the cooling agent (of about 0-5°C) in the heat pump thus extracted, is compressed using a compressor. Because of the physical qualities of this cooling agent a temperature of between 35-70°C results from this process.

Part 3 –Use of heat – Floor heating
Through a heat exchanger the heat pump delivers a temperature of  35-70°C to the heating pipe system under the floor which distributes the temperature throughout the house.

In the summer this process can also be applied to cooling by extracting warmth via the under-floor heat pipes and returning it into the earth. By cooling the building in the summer the subsoil becomes correspondingly warmer.
