Is Your Water Heater Losing Efficiency in Hard Water Areas?

By Eco Temp HVAC January 2, 2025

Hard water is a common challenge for many homeowners in the United States especially in Chicago and its surrounding suburbs. While the minerals in hard water—like calcium and magnesium—don’t pose a direct health risk, they can seriously impact the performance and efficiency of your water heater. If you’ve been noticing higher energy bills, inconsistent hot water, or strange noises coming from your system, it might be time to investigate the effects of hard water on your water heater.

In this post, we’ll explore how hard water affects your water heater, signs of inefficiency, and practical steps you can take to restore optimal performance.


What Is Hard Water?

Hard water contains elevated levels of dissolved minerals such as calcium and magnesium. While these minerals are not harmful to drink, they can cause scale buildup in plumbing systems and water-using appliances. This buildup can reduce the efficiency of your water heater and increase wear and tear on the system.


How Hard Water Affects Your Water Heater

Hard water can create several problems for water heaters, including:

1. Reduced Heating Efficiency

Mineral deposits, also known as “scale,” accumulate on the heating elements and inside the tank of your water heater. This scale acts as an insulator, making it harder for the water heater to transfer heat effectively. Over time, your water heater has to work harder, which increases energy usage and costs.

2. Shortened Equipment Lifespan

The buildup of minerals can corrode internal components, leading to leaks or system failure. This is especially true for traditional tank-style water heaters, which are more susceptible to sediment buildup than tankless models.

3. Increased Energy Bills

As efficiency decreases, your water heater uses more energy to achieve the same results, leading to a noticeable spike in utility bills. In severe cases, the added strain on your water heater can lead to system breakdowns.

4. Clogged Pipes and Valves

The same mineral deposits that accumulate in your water heater can also clog pipes, valves, and other components of your plumbing system, further reducing overall efficiency.


Signs Your Water Heater Is Suffering from Hard Water Damage

Wondering if your water heater is being impacted by hard water? Here are some common signs to watch for:

  • Reduced Hot Water Supply: Your hot water runs out faster than usual.
  • Popping or Rumbling Sounds: Noise from the water heater tank indicates sediment buildup.
  • Cloudy or Discolored Water: Scale or rust may be affecting water quality.
  • Slow Heating: It takes longer than usual for your water to heat up.
  • Higher Energy Bills: Unexplained spikes in your utility costs could point to an overworked water heater.

How to Prevent Hard Water Damage

Taking proactive steps can significantly extend the lifespan of your water heater and keep it running efficiently. Here’s what you can do:

1. Install a Water Softener

A water softener removes calcium and magnesium from your water supply, preventing scale buildup in your water heater and plumbing system. This investment protects not only your water heater but also your entire home’s plumbing infrastructure.

2. Schedule Regular Maintenance

Routine maintenance is key to preventing hard water damage. A professional flushes your water heater to remove sediment and checks for signs of wear and tear. At Eco Temp HVAC, we offer comprehensive water heater repair and maintenance services to keep your system in top shape.

3. Consider Upgrading to a Tankless Water Heater

Unlike traditional water heaters, tankless systems don’t store water, reducing the risk of scale buildup. Learn more about the benefits of tankless water heaters, including their energy efficiency and durability.

4. Use a Scale Inhibitor

Scale inhibitors can help reduce the accumulation of minerals in your water heater, ensuring better performance and longer lifespan.
