Improves
the efficiency of solar heating systems!
Designed to control solar
powered pumps in closed loop solar heating systems, these
differential temperature controllers will improve performance by preventing
a solar powered pump from
running if the collectors become cooler than the storage tank.
This typically occurs on overcast days and early and late on cold
days when there is enough sunlight on the solar panel to power the
pump, but the collectors are not hotter than the storage tank.
