Our shop heating thermosyphon solar space heating collector is approaching 10 years, so I thought I would provide a run down on maintenance to date.
The maintenance has been minimal:
That's about it.
Since there is no fan and controller, there is no fan or controller maintenance.
The collector is vertical, so it does not collect snow at all, so no snow to clear after storms.
The glazing will probably have to be replaced at some point (15 years?), but it looks just fine now.
This collector is about as simple, reliable, and maintenance free as it gets.
