If you want to heat your pool as quickly as possible, a gas pool heater is your best bet. An above-ground pool can be a great addition to any, and with the addition of a solar heater, you will be able to enjoy it more. In my search to find a solar pool heater for installing anywhere, I stumbled upon this sunheatersolar pool heater. This heating blanket increases a 16000-gallon pool temperature to about 6 to 10 °F more. It also has a reel system, so when we need to store this solar heater because it’s off-season, we can easily roll it up.
