Electric Hot Water Heater Luke Warm Water Problem


I replaced the heating elements in my hot water heater a few months ago due to this same problem. Upon removing them i noticed the inside has some calcium buildup and the elements had been corroded. I flushed the tank as well as I could using the cold water flowing through the tank and did this until I saw no more sediment coming out. Fast forward 3 months and I have luke warm water again. I have increased the temp on my thermostat but this only temporarily resolves the issue. Where do I go from here?

Electric Hot Water Heater Luke Warm Water Problem


Hard water is a death sentence to electric water heater elements. I worked at a place that was so bad that three year old tanks where 1/3 full of sediment. Flushing only removes the small particles. We had to "dig" them out through the hole where the bottem element goes in. An appropriatly sized tube attached to a good shop vac and about an hour out of your life will get most of it out.

If it's that bad get the water test to see what treatment is called for.
May need a water softner.

I am on public water. Didnt know it give me issues like this. If i ised a hose with a nozzle on it to flush out the calcium on the cold water tube would it hurt the water heater?

The place I was at was on public water too. It was an apartment community so softeners were not standard equipment. (Should have been though) The issue we had with flushing was that it left too much rock behind and the new element was assured to last less than a year.
