Question about Rinnai Heating & Cooling
there is a problem with your solar / electric hot-water system. The fault should be from the solar outside, probably its not passing enough current to the hot-water system, that's why the water is not getting hot. Or the heating element might be bad.
Most electric hot water heaters have two thermostats, one near the top of the tank and one near the bottom, and are covered by removable metal cover plates. The thermostats are pressed firmly against the bare metal wall of the hot water heaters tank.
First remove the upper thermostat cover plate and check the high limit switch button. If it has tripped, press it to reset it.
Check for power at the input terminals of the upper thermostat. (usually marked L2 and L2) If no power is present then check your circuit breakers or wiring to the water heater.
If there is no hot water then the upper thermostat should be applying power to the upper heating element. Check for voltage at the upper heating element. If there is power at the heating element but the element is not getting hot then the heating element needs to be replaced.
If there is no power at the upper heating element then the upper thermostat needs to be replaced.
If you cannot carryout the above troubleshooting yourself, then maybe you should care repairman to help you fix the problem.
I wish you good luck.
