The delivered quality and satisfaction is known to me through relatives (customers of Brenner). The workmanship there looks top notch.
Customer service logically takes a bit longer due to the amount of requests.
However, the advice is poor, only things were shown why something does not work, no solutions or explanations that it is not worth it or would be too expensive. It was also not addressed to possibly use other products, this is not possible.
For us, it seems that no energy transition is promoted here and no money wants to be earned (enough other simpler orders).
Thank you very much for your honest feedback and for your wish to improve us with your evaluation. And we are very keen to guarantee our quality standard for each of our customers. For this reason we would be pleased to hear from you by e-mail. Please send us your contact details to Info@brenner-energie.de, referring to this review. We take your criticism seriously and will try to satisfy you!
With kind regards
Managing Director of Brenner Energie GmbH
