Good day. Our neighbor needs to repair his solar piping in the attic. It is leaking. Now he wants to drain the solar fluid and only refill it again in spring. The oil heating system is designed so that the solar system is not absolutely necessary. (It was installed afterwards). Question: -Does he have to expect frost damage to the collectors if he drains the solar fluid and leaves the system as it is over the winter? The pump, etc., will of course be switched off. Or can he do this as an exception. Thank you very much
