Diesel heater in summer

Hello together, even if others think of ice cream with vanilla, I have not forgotten my SH. No, I don’t want to copy any of the various SH freds, because the topics when/whether/how the SH does (or not) have been discussed a lot. But, I remember from a Fred that one should let the SH run manually even in warm seasons. Therefore here again concretely: Do you let your SH run in warm seasons? If yes, how often and how long? (Elchwiki says “in the A I am currently at once a month, five minutes, but I have no idea how suitable that is.) Greeting xc90s …he hopes that he will not ask for a pack of Haumichblau here.
