All mechanical equipment has an expiration date, and as a consumer, it’s important to know when you can expect certain systems and appliances may need replacement. However, a lot of factors can affect when you may need to replace a product, including proper usage and maintenance. When it comes to pool heaters, there is a fairly wide range for lifespan expectation; on average, it is 6-12 years. What can affect the lifespan of your pool heater? Here are a few things to keep in mind:

Chemistry of Your Pool Water

Pools balance a number of chemicals both organic and added that help keep the water clean to swim in. It’s recommended that you test your pool water weekly to make sure that it is in proper balance, especially where alkalinity and calcium are concerned. When the alkalinity isn’t balanced, the lack or excess of acid in the water can hasten corrosion, as can too little calcium. Additionally, too much calcium can lead to scale, which restricts water flow. The best way to ensure that your pool maintains healthy chemistry levels is to conduct a weekly water test.

Effect of Power Problems

Your pool heater needs power to operate and as such is connected to your main line of electricity. However, should you experience power outages or surges of power due to weather events or other reasons, so, too, does your pool heater. If your pool heater is the subject of many power ups-and-downs, these surges may cause premature aging and damage.


Your pool heater should be scheduled at least once a year for maintenance, and can benefit from bi-annual maintenance. During a maintenance appointment, your pool heater will be thoroughly inspected, components will be cleaned, lubricated and adjusted, and the unit will be tested for safety and performance.

With regular maintenance and attention to your pool’s water chemistry, you should be able to make your pool heater last for a number of years. Have questions? Call the trained experts at Air On Demand and schedule an appointment today for professional pool heater service in Homestead.
