What Is The Most Efficient Way to Heat a Pool?

Of course, that all depends on the above factors.

  • Gas powered heaters are the most efficient when it comes to reliable and quick heat, but they can be very expensive to operate on a regular basis.
  • Electric heating pumps are more cost effective in the long run, though the upfront cost may be greater than that of a gas heater and they are more dependent on the air temperature being mild to function properly.
  • Solar heaters are the most cost efficient of all the ways to heat a pool, but as with electric heat pumps, they are dependent on sunny, warm weather and won’t work well in very cold or primarily overcast climates.

Choosing the most efficient pool heater all depends on your budget and needs and the overall climate.

What Size Heater Should you Get?

Again, it depends on how fast you want your water to heat, how often you intend to use your heater, and of course, how big your above ground pool is. The higher power the faster the heat and the bigger the pool, but it will also have a greater price tag.

Is it Worth it to Heat an Above Ground Pool?

Ultimately that is up to you and your needs, but as you consider your options, let’s look over the 5 best above ground heaters available (gas, electric, and solar) and you can get a better idea of what might work best for you.
