Since 2020, Ralph N. from Singen (Germany) is the proud owner of a SenerTec Dachs 0.8 fuel cell unit. He and his family can now generate their own heat and electricity in a very efficient way for their 280 square meters single-family house.
Furthermore, the family successfully refurbished their house to become more energy efficient by replacing the single-glazed windows with triple-glazed windows. Within this renovation process, they replaced their old condensing boiler with the state-of-the-art fuel cell heating system Dachs 0.8.
Ralph N. is particularly pleased about the savings due to the refurbishment: “The entire renovation work has reduced my gas consumption by 75%. The fuel cell‘s own electricity production has so far resulted in electricity cost savings of almost 50%.” The basic electricity requirement for electric endurance runners such as refrigerators, freezers and standby devices can be covered very well. And on top of that, there is still something left for partly covering the rest of the remaining demand.
Also in the future, Ralph N. wants to rely on highly efficient technologies: “Due to the positive experience with fuel cells, we will install an additional Dachs – a little bit larger in size – in our new building with 11 rental units to keep the ancillary costs of the tenants as low as possible.” This is how we can combine environmental awareness with added value for the tenants.
