Heat pump - a strong alternative

Die öffentliche Diskussion ist hitzig. Der Vorstoß der Regierung, schon für 2024 den Einbau für Öl- und Gas-Heizungen zu verbieten wirft erstmal viele Fragen auf, setzt dich aber nicht wirklich unter Zugzwang. Denn bestehende Heizsysteme können ja nicht nur weiter betrieben, sondern auch bei Defekten repariert werden. Trotzdem gibt das neue Gebäudeenergiegesetz Anlass, über das Thema Heizen nachzudenken. Und zwar mal in aller Ruhe. Wir haben den Fokus auf die Wärmepumpe gelegt.

Champion of energy efficiency: the heat pump

The principle can be easily explained using the example of a refrigerator. This is because a refrigerator is also a heat pump. Heat that enters the refrigerator from outside is channelled out again via the grille at the back. A heat pump as a heating system does the same, only in reverse: it draws heat from the environment and channels it into the house. Just like the refrigerator, the heat pump works with electricity. However, the electrical power consumed is low, while the heat output (or cooling capacity) is high. A very efficient system, therefore, which is even as environmentally friendly as possible thanks to the utilisation of natural heat energy.

Many paths to warmth

Heat pumps are available in a wide variety of versions. However, the principle is the same for all of them: an evaporator, a compressor, a condenser and an expansion valve form a closed circuit through which a refrigerant flows. This evaporates under gentle pressure, absorbing heat energy and transferring it to the house's heating system. - A continuous process.
Where does the heat pump get its heat from? There are several sources.

1

Groundwater

Groundwater is particularly effective. However, certain conditions must be met for this, including a low iron and manganese content. You also need a licence

2

Geothermal energy

Geothermal energy is obtained either through large-scale ground collectors (this requires sufficient ground space, a garden would be destroyed by the installation in the meantime) or through vertical sinking of geothermal probes that reach a depth of 200 metres.

3

Air-to-water heat pumps

You often see these eye-catching cabinets: these are outdoor units of air-to-water heat pumps that utilise the air as a source. Of course, this is not so favourable in winter. As a rule, an integrated electric heating element then helps to provide the required heat. However, the fan generates noise that can be perceived as disturbing.

Heat pump & smarter home - best friends

Busch-free@home®, the system for the smarter home from Busch-Jaeger, integrates a heat pump perfectly into an energy management concept. Ideally in combination with a photovoltaic system and battery storage (e.g. from wibutler). Intelligent networking not only automates and thus optimises the control system, but also precisely coordinates the distribution of electricity. This means maximum efficiency.

Conclusion

Fossil fuels are already expensive today and will also be subject to certificate trading, i.e. CO₂ pricing, in the future. They are also bad for the environment. Low-maintenance heat pumps, which also have a long service life and operate emission-free, definitely create a win-win situation.

- Once installed, they save considerable energy costs in the long term.
- They actively contribute to improving the climate.
- On top of this, there are also state subsidies that can give your project an extra boost.

It is definitely worth talking to a specialist.
