How Water Quality Impacts Your Water Heater's Performance

How Hard Water Affects Your Home’s Water Heater

Hard water is a common issue for many homeowners, and it can wreak havoc on your home’s plumbing system. One area that hard water is especially problematic for is your home’s water heater.


Hard water contains minerals like calcium, magnesium, and iron that can build up in your pipes over time. This buildup can cause an array of issues, including reducing the efficiency of your water heater.


Let's take a look at how hard water affects a home's water heater and what you can do to prevent any long-term damage.

The Impact Of Scale Buildup On Your Water Heater

One of the most common issues with hard water is scale buildup in your pipes. Over time, calcium and other minerals present in hard water will accumulate along the walls of your pipes and form a thick layer called “scale.”


Scale buildup reduces the flow of hot water through your pipes, reducing the efficiency of your water heater. This means that it will take longer for hot water to reach its destination, resulting in higher energy bills and shorter showers!

Preventing Scale Buildup In Your Water Heater

The best way to prevent scale buildup from occurring in your home’s plumbing system is to install a water softener or descaler device on your home’s main line. A good quality device should be able to remove harmful minerals from the incoming source before they enter into your home's plumbing system.


This will reduce the amount of scale that builds up over time and help maintain optimal performance from your home’s heating system. Additionally, regular maintenance, such as flushing out sediment or having a professional inspect and clean out any blockages, can also help keep scale buildup at bay.

Tips For Maintaining Optimal Performance From Your Home's Water Heater

Hard water can damage human consumption and appliances such as washing machines and dishwashers. Here’s how to stay on top of your water heater:

  • Regularly drain and flush out sediment from the bottom of your hot water tank.

  • Regularly check for signs of corrosion or leaks around fittings or valves.

  • Have a professional inspect and service your tank annually.
