Features To Consider When Choosing the Best Above Ground Pool Heaters

While above-ground pools have become increasingly popular, one of the main complaints is that they can be quite chilly, especially in the evening when the sun goes down. A good above-ground pool heater will extend your swimming season by keeping the water at a comfortable temperature so you can enjoy a dip any time of day or night. Here are some features to look for when choosing an above-ground pool heater:

  • Size And Power: Above-ground pool heaters come in various sizes, so it’s important to choose one that is powerful enough to heat your pool. The pool’s gallon capacity will determine the size of the heater.
  • Fuel Type: Above-ground pool heaters can be powered by gas, electricity, or solar energy. Gas-pool heater is the most popular because they are the most efficient but can be more expensive. Electric pool heaters are less expensive, but they take longer to heat the pool and don’t work as well in cooler weather. Solar-powered heaters are the most environmentally friendly option but are also the least powerful and can take longer to heat up the pool.
  • Heating Time: The time it takes for an above-ground pool heater to heat the pool will vary depending on the size of the heater and the temperature of the water. It will take longer to heat up a large pool than a small one.
  • Thermostat: A good above-ground pool heater will have an adjustable thermostat so you can set it to the desired temperature and then let it do its job.
  • Safety Features: Look for an above-ground pool heater that comes with safety features like automatic shut-off and tip-over protection. These features will help prevent accidents and injuries.
  • Price: Above-ground pool heaters range in price from around $100 to $1,000 or more. Choose the one that fits your budget and needs.

What Size Heater Do I Need For My Above Ground Pool?

The size of the heater you will need depends on several factors, including the size of your pool, the average temperature in your area, and how often you plan on using the pool. In general, however, a heater between 75,000 and 100,000 BTUs should be sufficient for most above-ground pools.

Solar pool covers, blankets, and a solar pool heater can capture the sun’s rays and transfer them to the water, providing free heat for your pool.

Finally, you can also harness the heat from the earth by installing a geothermal pool heating system.
