Setting your solar thermal system differential temperature setpoint.

Q:What is the most appropriate differential temperature for my solar thermal system?
A: The factory setting on our controllers is 12 Degrees. This will work fine but for northern climates it is better to have a delta T of 17 Degrees. This will allow the collector to heat up sufficiently so as to not turn the pump on and off early in the cold mornings. In warmer climates, say mid-latitude and below you can keep the factory setting at 12 deg F.
