oh yes, in another forum I was advised to additionally install a solar thermal system on the roof. this way I could shut down the LW pump during the summer months.

Any opinions on that?

so this is complete nonsense...the investment costs for a solar thermal system will never be recovered...you can calmly heat with the heat pump and overall it looks better in the end...
