Here are some common causes of pool heater failure.

Hard Water & Mineral Buildup

Hard water is usually the main culprit behind a damaged water heater. Hard water is a term used to refer to water that has a high volume of minerals dissolved in it. Oftentimes, these minerals include magnesium and calcium. As your heater warms the water, some of it will evaporate into steam; when this happens, the residual minerals will build up on the heater. This buildup will look like a white powdery coating on your heater. This can damage the heat exchanger and prevent your heater from heating the pool water. 

How to Protect Your Heater Against Mineral Buildup

To combat mineral buildup, you need to regularly the hardness of your water and apply water softener when necessary. A high pH can also contribute to mineral buildup. So, ensure that you periodically test the pH of your pool water and balance it so that it sits around 7.5.

Corrosion Due to Poor Water Chemistry

The pH of your pool water can also cause your pool heater to corrode. Maintaining a neutral pH in your pool is absolutely essential to creating a safe and comfortable experience for swimmers. A low pH is an indicator of acidic water, which can cause skin and eye irritation. Acidic pool water can also corrode the metal elements of your pool heater, causing them to wear down and even break. This will result in pool heater failure over time.

How to Protect Your Heater Against Corrosion

Balancing your pool water regularly is key to preventing any type of corrosion. Many pool owners will utilize testing strips on a monthly or biweekly basis to get a pH reading. If your pool’s pH is too low, add a pH increasing balancer to create neutral pool water. The ideal pH range is between 7.2 and 7.8.

How to Know When Your Pool Filter Needs Replacement vs Cleaning
