Solar hot water panel differential pump controller by extreme circuits friday april 19 2013 this circuit optimises the circulation of heated water from solar hot water panels to a storage cylinder.
Solar hot water panel differential pump controller circuit.
Solar hot water panel differential pump controller this circuit optimises the circulation of heated water from solar hot water panels to a storage cylinder.
Control the main solar panel circuit pumps at 2 levels reducing water flow as temperature delta decreases via lead and lag pumps lets the system collect solar more efficiently publish temperatures and pump status to a web page and provide the same pump control as available on lcd user interface.
First of all it is worth noting that there are solar hot water system designs for which a controller is not required.
It achieves this by controlling a 12v dc pump which is switched on at a preset temperature differential of 8 c and off at about 4 c.
The material below provides a full description of the design notes on what drove the design issues to keep in mind if you use or alter the design for your system details on the hardware assembly and full software listings for the controller software.

This circuit optimises the circulation of heated water from solar hot water panels to a storage cylinder.
It achieves this by controlling a 12v dc pump which is switched on at a preset temperature differential of 8 c and off at about 4 c.
The controller is there to turn the pump on when the fluid in the solar panel is hotter than the water in the hot water tank or swimming pool and keep it turned off at all other times.
Solar heater controller solar thermostat switch differential temperature controller for solar hot water.
It achieves this by controlling a 12v dc pump which is switched on at a preset temperature differential of 8 c and off at about 4 c.
This method of control has distinct advantages over some systems that run the pump until the differential approaches 0 c.
