PAUL Net Zero pi­lot pro­jec­ts

The pilot projects for our PAUL Net Zero product have been successfully launched! On this page, we regularly provide an insight into the implementation of PAUL Net Zero and show that the heating transition for existing properties is possible. Already now.  

  
April 2025

In April, a total of 80 heat pumps plus housing parts were delivered to our new production site in Ladenburg. We are expecting a further 80 heat pumps by the end of April.

Due to the significantly larger amount of material, the increased production volume and the changed framework conditions of an expanded production environment, we have also invested in industrial trucks and on-site safety - and have redesigned our entire production hall and the adjoining rooms so that we have significantly more space.

The 80 heat pumps delivered are now quality-checked and parameterized by our production team and then commissioned with the piping sets and housings we produce.

The finished PAUL heat pumps will then be sent to our customers' properties as a complete package – we plan to connect around 850 residential units to PAUL Net Zero in this way in April.

March 2025

Following the successful launch of the first pilot buildings, four further pilot projects are now nearing completion. The results show: CO₂-neutral existing properties can be realized in a short time and without expensive renovations.

At the same time, we have started planning for the entire portfolio - the first award processes are already underway for a volume of around 1,000 residential units.

We are also moving into the next gear operationally: the scaling of our operations organization is in full swing in order to make PAUL Net Zero available nationwide.

In the video interview below, Tobias Risel (Chief Operational Excellence Officer) and Timo Jäger (Head of Technical Engineering) provide exciting insights into the current status of the project work and report on their experiences and initial results in the implementation of the pilot projects.

January 2025 

Just one month after commissioning, we were able to record an increase in efficiency in the property mentioned below. The flow temperature was reduced from 70 °C to 53 °C. We also achieved a reduction in primary energy consumption and CO₂ emissions. The energy efficiency class of the property was significantly improved from E to A.
