Rabmer as a member of the Austrian Heat Pump Association
The trend towards ecological heating systems is continuing. In particular, energy from waste water is becoming increasingly important as a renewable energy source. Rabmer has decided to become a member of the Austrian Heat Pump Association in order to further promote this topic. We presented our company and our technologies at the general meeting in Carinthia at the beginning of July.
This year, the general assembly of Wärmepumpe Austria was held in Techelsberg am Wörthersee in a beautiful location and a great atmosphere. The two-day program offered exciting presentations and a lively exchange of information in addition to the general assembly, at which the new board was elected and a nice get-together.
Our head of Rabmer GreenTech, Klaus Pichler, gave a presentation explaining the advantages and possibilities of generating energy from wastewater. Under the right conditions, warm wastewater can be used both inside and outside buildings to heat and cool buildings, as well as to heat water and thus save fossil fuels in a highly efficient way. The applications start with the use of heat exchangers in showers and end with highly efficient heat exchangers combined with heat pumps for the use of sewer wastewater heat for the complete heating and cooling of buildings.
The range of available technologies is wide and innovative solutions are constantly being added. The projects are correspondingly economical and efficient, and payback periods of 3-5 years are now realistic.
The use of this sustainable, renewable energy source will shape the future of heating and cooling buildings. Ideal conditions can be found above all in larger cities, where sewers with sufficient waste water volume (at least 10 l/sec) are available and potential consumers are located in the immediate vicinity. Further potential can of course also be found in industry or sewage treatment plants. Office buildings, residential buildings, hotels, hospitals, retirement homes and schools are just a few examples of suitable applications. In addition, work is already underway to utilize wastewater heat for feeding into the secondary network of district heating operators. Calculations show that in future, 5 - 15 % of the heating requirements of buildings could be covered by energy from wastewater.
This gives us an idea of how much energy from our sewers and wastewater pipes will be used in the future for the benefit of our environment! We are pleased to be working together with the Austrian Heat Pump Association to make this technology more widespread in Austria.
