Review: EASY TO USE,GOOD VALUE - FIT AND WORKED PERFECT IN A SINGLE HEATING ELEMENT HOT WATER HEATER
Review: We have hot water again after weeks of showering at the truck stop - We just had our furnace go out and paid $500 for a fix, and then the hot water heater went out. We slowly went from only having a few minutes of warm water to 5 seconds of warm and then just cold. I replaced the heater element but still no change, and then bought another one and changed it still no luck. Frustrated and ready to shell out the money for the comfort of hot water I tried to replace the thermostat after researching more online. So I decided that I would try it and it worked!!!! We could feel the hot water in the matter of minutes! And we save hundreds on a repair
