How to Remove Calcium Buildup from A Water Heater?

Got no hot water at your house? There are a lot of different reasons your water heater may not be working, and if you have hard water, one of the most common causes is calcium buildup on heating elements.

Calcium is found in many municipal water supplies in small amounts. Over time, calcium will collect with other sediments in your water heater. If your water heater is not working or the hot water is strangely colored, this may be the cause of your issue.

How to Remove Calcium Buildup from A Water Heater?

Here are two common ways to remove calcium buildup from water heaters.

  • Flush the water heater – This should be done once per year to reduce calcium buildup. This simply involves turning the water heater off and letting all of the water (and sediment buildup) drain out.

  • Use chemical treatments – If you already have a lot of calcium in your heater, you can flush the tank, then pour vinegar into the hot water tank, and let it sit for a few hours. Then, just flush the tank thoroughly to remove the vinegar and calcium.

If flushing the heater and using chemical treatments does not work, you may have too much calcium buildup, or the issue may be unrelated to calcium deposits. Contact a plumber to get to the bottom of the problem.

Prevention Is Better Than Removal – Keep Your Water Heater in Good Shape

Ideally, you should avoid calcium buildup on heating elements completely. If you have hard water that’s high in calcium, you should use a lower temperature for your water heater. Keep it closer to 120 degrees, as higher temperatures tend to leave behind more calcium.

An even better option is to invest in a water softener if you have hard water. A water softener will remove calcium and other minerals like magnesium from your water, which will prevent calcium buildup on heating elements. With a water softener, you won’t have to worry about having no hot water due to mineral deposits in your hot water tank!
