I built a system awhile back for Hot water
concisting of a solar
heater that sits between the solar electric
atop the bimini
.. Durring the hottest part of the day I cycle the water throu the colector and fill the waterheater with hot water, works great EXECPT,
I personally have to turn the pump on and turn it off..
Id like to install a tempeture differential system that would turn the circulation pump on and off based on the difference of the tempeture on the heater and the colector..
Anyone have any Ideas on the workings of a defferential system that would work for the system..
I've checked into the home units but they all run on 110 and I would like to set it up for 12 volt...
