Three Swimming Pool Heater Options

Swimming in a heated pool is not only comfortable, but it offers many benefits for people with medical conditions that can be helped by heat. However, if you have an older pool with its original heater, then keeping the water heated can be expensive. One of the best ways to save money and keep the water warm is to replace the old pool heater with a more efficient heater. 1369800799_iStock-000010263358Large Types of Swimming Pool Heaters

If you have decided to replace your pool’s heater, there are three different types of heaters from which you can choose, including:

  • Solar Pool Heaters
  • Gas Pool Heaters
  • Electric Pool Heat Pumps


Solar Pool Heaters

For most residential swimming pools, a solar pool heater will keep the water at about 26 to 29 degrees Celsius during the warmer months of the year. The sun’s heat is used to warm the water when it is circulated through the heater by the pool’s pump. The timer on the pump is usually set to work during the daylight hours, typically from 9 a.m. to 5 p.m., depending on the time of year.


A solar pool heater is one of the most cost-effective options, because the heat generated by the sun is free. However, when the weather is bad, it usually doesn’t keep the pool water warm enough for swimming. The cost of a solar pool heater will depend on your pool’s size and the weather conditions where you live.

Gas Pool Heaters

If you use your pool frequently, then this is the most expensive option for keeping the water warm. However, if the pool is only used occasionally, such as when your children have friends over, then it can be a quick way to heat the water in the pool. No matter the weather, a gas pool heater will help keep the water warm enough for swimming.


Gas pool heaters use either propane or natural gas fuel for warming a residential pool, so you either need a nearby storage tank for the propane, or a natural gas line running to the heater. The gas is burned in a combustion chamber and the heat is then transferred to the water in the pool. They can be inefficient at heating your pool and can add to the operation costs.

Electric Pool Heat Pumps

Even though they run on electricity, a swimming pool heat pump can be an efficient way to heat the water in your pool. These pumps are a type of solar heater because they extract the heat from the air and transfer the heat to the water with the aid of a compressor. They can warm the water in your pool during most of the year, as long as the air temperature is at least 7 degrees Celsius.

As long as the heat pump is sized correctly for the pool, then it should keep the water between 26 to 32 degrees Celsius. If you want to swim year-round, a pool heat pump is your best and most efficient option.
