You’ll need to connect it to your gas pipe in which Gas pool heaters are well-suited to larger pools as they can heat quickly just keep an eye on the price of gas as you might be less inclined to use the pool if it fluctuates the wrong way.
  • Electric Heat Pump – Using ambient heat they are slower to warm the pool but are relatively energy efficient in comparison to a regular electric system. An electric heat pump transfers warmer air into the system and pushes cold air away so your pool only gets the warmth. They aren’t as powerful as other types but are more cost-effective.

Does Climate Affect A Pool Heater?
