  • Works well in our above ground pool.
We were skeptical about using a heater for an above ground pool but this one is great. Very easy to install and set. It took several days for the water to warm up but we are very happy with this product. We have an above ground pool that is 12x24 and holds 8000+ gallons of water. We live in Indiana so our days are warm and the nights can be a little cooler. The thermostat is accurate and the heating unit turns off when the desired temperature is reached. For the price, it is a great value. As far as durability, we have only used it for a few weeks but are completely satisfied. ... show more
