Which Pool Heating System is Right for You

Pool Heating System

A pool heater ensures that your pool is always at a comfortable temperature and allows you to extend your swimming season. There are many different types of pool heaters available. Here’s a brief description of your options to help you determine which pool heating system is right for you.

Different Types of Pool Heaters

The different types of pool heaters are:

  • Gas
  • Electric
  • Geothermal
  • Solar

Gas Heaters

Gas pool heaters use natural gas or propane to heat the water and can heat a large volume quite fast. This makes gas heaters great for large pools and pools that aren’t used every day. They can maintain a set temperature, which is great for those living in cooler climates.

Gas heaters cost more to run than other types of heaters but the cost can be reduced by using a pool cover or a secondary pool heating system after the preferred temperature has been reached.

Electric Heaters

Electric pool heaters, also called heat pumps, transfer heat from the outdoor air to the pool water using a heat exchanger. These heaters work best in warmer climates where the margin between the desired water temperature and the air temperature remains above 45-50 degrees F.

Electric heaters take a bit longer to heat the water and must run all the time to keep the water warm. These heaters are more cost effective than gas heaters if you use your pool all the time.

Geothermal/Ground-Source Heaters

Geothermal heaters transfer heat from the ground to the pool water using antifreeze-filled pipes buried in the ground. Geothermal heat pumps are not affected by cold temperatures during the winter and so can be used year-round.

The disadvantages of the system are that you will need a large area of land to install it, the high cost and slow heating. However, geothermal heaters only use electricity to transfer heat, rather than creating it, making it very energy-efficient.

Solar Heaters

If you are looking for an eco-friendly solution for heating your pool, a solar pool heater is the answer. Not only can it heat your pool water, but is can also power your pumps and outdoor lighting. Investing in solar panels now will save you money in the long run.

Solar pool heaters consist of large black panels that are mounted on the roof of your home, pool house or another adjacent structure. Direct (open loop) solar pool heating systems can be used in warm regions that do not experience freezing temperatures. Indirect (closed-loop) systems are better for colder areas because they can reach higher temperatures.

This heater uses your existing pool pump to collect water and heat it by the sun’s energy. The water is then returned to the pool and the cycle repeated until the pool has been heated.
