System type: Pumped - differential controller
System is no longer operating.
Pipes in the flat plate collector split during a freeze in 1998. Client indicated 2-4 tubes had burst. The client had the installer try to repair it, unsuccessfully, since the piping started leaking again. The system was then isolated. Eventually the water heater was replaced and the system plumbing was disconnected completely and all interior system components removed. All that remains is the solar system is the collector still mounted to the south side of the house. Interesting mounting location.
