Product Description:

For larger buffers with more than 100 liters per square meter of collector area or for very large solar systems, a layered charging module ensures efficiency when integrating a thermal solar system. When the sun is weak, for example in the morning, the module feeds into the lower half of the buffer. When the sun has enough power to heat the upper, warmer buffer layer, it switches to that.
