Installer Survey: Turning regulatory and market changes into customer value

While 89 percent of 336 surveyed German installers are familiar with HEMS, only 25 percent have already gained practical experience with it. Find out why HEMS are so important and how the current gaps can be filled in gridX's latest whitepaper.

Executive summary

gridX and KOSTAL survey of 336 installers

01

89 percent of surveyed installers are familiar with HEMS; 56 percent have already recognized the added value of the technology.

02

26 percent of German installers have already gained practical experience with HEMS.

03

Only 27 percent of all surveyed installers would rate themselves as familiar or very familiar with dynamic tariffs.

04

44 percent of respondents said they have a good understanding of Paragraph 14a of the Energy Industry Act (EnWG), which has had a binding impact on users of controllable energy-consuming assets since January 1, 2024.

05

The biggest hindrances to the adoption of HEMS are perceived high investment costs, complexity of the topic around renewables and home energy management, as well as fears of reliability and compatibility.

06

gridX and KOSTAL now want to build on the results of their collaboration under ‘Ready for gridX’ and work together to overcome the reservations of installers and homeowners through targeted information.

gridX and KOSTAL's survey of 336 German installers shows that installers already have a good idea of the functions and benefits of a home energy management system (HEMS), but that the path to the actual introduction of a HEMS and the concrete implementation of relevant use cases is still unclear.

The benefits of HEMS are attractive to end users and installers alike, but many installers are still in the early stages of truly understanding and applying advanced HEMS in the field. In summary, installers want a future-proof HEMS that simply works.

With a HEMS “powered by gridX”, combined with KOSTAL's cutting-edge technology, the challenges in the market - cost, complexity, reliability and effort - can be turned into customer value: Savings, support, compatibility and ease.
