I remember in a video, Linus measured that the ground absorbs all the heat before it could even reaching the pool.

His pipes have too much or not enough insulation then.

I don't know anything about the topic and this made me really curious. Why could too much insulation be a problem?

It then just acts like the ground does and just absorbs the heat instead.
