Regular Maintenance Checks

Like any other equipment, pool heaters require regular maintenance checks to keep them in good condition. Here are some maintenance tips to keep your pool heater in peak working condition:

  • Schedule annual maintenance from certified technicians to inspect and tune-up all internal components of your pool heater.
  • Clean the filter system to prevent blockages, as this can cause a reduction in water flow, which puts extra strain on the heater’s internal components.
  • Regularly check for leaks in the pool system and heater’s internal components. A small leak can cause significant damage to critical parts of the heater.
  • Keep the area around the pool heater clean and clear. Remove dirt, debris and any other sources of contamination that may cause damage to the equipment over time.

Proper Installation

The pool heater’s installation is as important as maintenance checks for its longevity. Improper installation of a pool heater shortens its lifespan and may void the manufacturer’s warranty. Follow these guidelines when installing a new pool heater:

  • Have a professional installer install the pool heater to avoid mistakes that can create potential safety hazards.
  • Ensure that the heater is installed in an area where it is protected from weather elements, particularly rain and snow.
  • Confirm that the electrical and gas connections are installed accurately and comply with local codes and regulations.

Using A Pool Cover

Using a pool cover is a practical and effective way to keep your pool heater in good condition. Besides, it helps to conserve energy, reduce chemical usage and decrease pump run time. Here are some reasons why using a pool cover is essential for pool heater longevity:

  • Reduce water loss through evaporation, decreasing the frequency of adding water to the pool
  • Protect the pool heater from the weather elements, prolonging its lifespan
  • Minimize debris in the pool, reducing chances of blockage that puts strain on the heater’s system.

Keeping Chemical Balance In Check

Keeping the pool water’s chemical balance in check ensures that the pool heater operates optimally and efficiently. Chemicals added to the pool water balance can cause corrosion or damage to the heater. Here are some best practices for keeping chemical balance in check:

  • Maintain a proper ph balance level between 7.2-7.8 for chlorine and bromine systems and 7.0-7.2 for salt water systems.
  • Check the pool water chemistry at least once a week, and adjust chemical levels promptly following the manufacturer’s recommendations.
  • Never over-lower the ph level of the water, especially during the off-season period, as this can cause corrosion to the heater’s internal components.

Following the best practices of pool heater maintenance, installation, using a pool cover, and keeping a chemical balance in check ensure an extended lifespan for your pool heater, saving you money and potential stress from breakdowns. Implementing these strategies can address minor issues early and prevent significant damages and costlier repairs later on.
