System type: ICS system
System is still operating.
The solar collector is mounted facing north on a north facing roof. The roof has a very low slope. The angle is only about 5-degrees so the collector does receive solar radiation.
Client states (via telephone) that the system is still operating. Unable to get into house since client did not come to the site at designated time. Contacted the person who had replaced the water heater and was told that he had replumbed the new heater to the collector loop.
