Hello everyone,
I am currently in talks with the first heating engineers. The centerpiece will be a pellet heating system (15kW) -> ETA or KWB. Since I have only heard good things about a solar combination so far, I wanted to implement this now as well. I expect (almost) complete savings of pellets in the summer – solar should be sufficient for pure hot water preparation.
After the conversation with the heating engineer, I am now somewhat uncertain. He told me about problems with such a combination, as too much heat is generated especially in the summer (since hardly any water is needed from the buffer tank), and the glycol in the solar panels partially even evaporates because it gets too hot. He, on the other hand, would rather use photovoltaics and implement heating support with an electric heating rod. I heard about this problem for the first time and also cannot find much about it on the internet.
What do you think about this? Maybe one of you has experience with one of the two heating technologies.
Best regards,
