The Three Above Ground Pool Heater Types
There are three ways to heat your pool water. Below are the types of pool heaters available and how they work.
Solar Pool Heaters
The sunshine is FREE! And it's readily available the world over. So take advantage of a solar heater for your pool water and you'll only have to make the initial investment of the water heater unit. These solar water heaters do take up a lot of space, but they can be mounted on a roof or any other elevated surface where it will get the most sunshine during the day.
If you're unsure of how much solar power surface you need to heat your pool water, use this simple conversion formula:
1. Find the surface area:
Round Pool: Area = R x R x 3.14
Rectangular Pool: Area = L x W
2. The surface area will be the amount of square feet you need of solar panels to warm the water in your pool. To get the square feet of the solar panels, multiply W x L.
A round, above ground pool that is 24 feet around would calculate like this:
12 x 12 x 3.14 = 452.16
You would need at least 452 square feet of solar panel surface.
Solar pool water heaters are eco-friendly and cheap to operate as long as you have enough sunlight to heat the water circulating from your pool. Check your size pool to estimate the amount of square footage needed and then purchase panels like the SmartPool S240U Universal Sun Heater panels for warmer water and enjoyable swimming.
Gas or Propane Pool Heaters
A unit that is made to heat pool water and runs on gas or propane is made with a combustion chamber that has a burner to warm the circulating pool water. Depending on whether you have gas lines available from your home, you can purchase a pool water heater like the Hayward H200FDN Universal H-Series 200,000 BTU Pool and Spa Heater, Natural Gas and use it with natural gas or propane. Some heaters have a Millivolt ignition where a small amount of gas is emitted to keep a pilot light lit. Electronic ignition uses less fuel and is easier to light, also avoiding pilot lights blown out due to wind.
Gas water heaters provide warmer water faster than a solar heater, but will cost more to operate.
Pool Heat Pumps
Similar to a gas pool water heater, your pool water will pass through a unit to heat the water and returns it to the pool, but instead of gas, a heat pump uses an evaporation system. The heat pump uses a fan that moves outside air and pushes it over an evaporator coil, warming it and turning it into gas. This warm gas then goes through a compressor to increase the heat and then sends it through a condenser that heats our pool water.
Heat pumps are typically less expensive to run than gas water heaters. Our top pick, the Hayward HP21404T HeatPro Titanium 140,000 BTU Heat Pump, is a reliable and highly rated water heater with a long track record of Hayward company quality.
