The Intex 28684 Electric Pool Heater is a fantastic solution for warming up smaller above ground pools. Users appreciate its ease of connection and effectiveness in heating water quickly, especially at the start and end of the summer season. However, it's crucial to ensure compatibility with specific pool types to get the best results.

The Intex 28684 heater is specifically designed for above ground pools measuring 8 to 12 feet in diameter. It effectively warms pool water to a comfortable temperature, making it ideal for extending your swimming season.

It's important to note that the heater operates within a range of 17 degrees Celsius to 35 degrees Celsius, making it suitable for a variety of weather conditions.

Connectivity and Compatibility

This model is easy to connect to your existing pool setup, requiring only a compatible pool cartridge filter pump with a flow rate between 500 to 2500 gallons per hour (1893 - 9464 litres per hour). It's specifically tailored for Intex Easy Set and Metal Frame pools, ensuring a snug fit. However, while it can technically fit larger 15ft pools, it is not recommended, which is a limitation for those with larger setups.
