This summer, when the temperatures were sunny and warm every now and then, the solar thermal system covers all of our hot water needs. The system was already on site before the heating system was converted and was taken over with the existing collectors, pump group and pipes on the hot water tank. The system is controlled via the electronics of the Fröling Lambdatronic SP 3200. Unfortunately, pressure loss creeps in more and more often after high outside temperatures, but the cause has not yet been identified. The system was of course refilled before commissioning and a pressure test was carried out over 2 weeks without any change. The installer suspected the expansion tank, but after the expansion tank was replaced, it unfortunately became even more noticeable. Perhaps you have similar problems and found a solution. Feel free to write it in the comments 😉 I look forward to your constructive suggestions and am curious.
