Solar water heater electric backup overheat trip
I have a customer with a SDHW system.
It is a 80 gallon tank with a 4*8 flat plate collector.
System is 6 yrs old.
Problem. From beginning the customer has complained about the reset button on the thermostat for the electric backup thermostat popping.Company that installed the system went back and installed a control to run the pump in the evening to cool the tank. This does not appear to have helped.
I replaced the thermostat and that solved the problem for about 4 months.
It has started up again.
Any ideas on solutions?
