Installation-Friendly Design

Our 15,000-gallon pool heaters feature a user-focused design that makes setup simple. Whether you’re installing the heater on a new pool system or replacing an older model, our clear instructions and standard connections streamline the process. For optimal performance, pair your heater with compatible valves and fittings to ensure smooth water flow and pressure balance throughout your pool system.

Superior Reliability

Our heaters can reliably handle a 15,000-gallon capacity. With durable components, corrosion-resistant exteriors, and weather-ready housing, they’re built to stand up to outdoor conditions season after season. For even greater efficiency and quieter operation, consider choosing an inverter heat pump, which automatically adjusts output based on your pool’s heating needs.
