The LEOMON KRY-8II is a professional heat pump designed specifically for villa and residential swimming pools. With an industry-leading coefficient of performance, it delivers exceptional energy efficiency—cutting pool heating costs by up to 80% compared to traditional electric or gas heaters. The unit features a titanium tube heat exchanger that resists corrosion from pool chemicals, ensuring long-term durability and stable performance. Operating at ultra-low noise levels, it provides comfortable heating without disturbing your family or neighbors. Compact, lightweight, and easy to install, the unit is the ideal choice for extending your swimming season and maintaining a comfortable pool temperature year-round.

With market-leading efficiency, the unit delivers multiple kilowatts of heat for every kilowatt of electricity consumed. This translates to substantial energy savings compared to conventional electric or gas pool heaters. Though the initial investment is moderate, villa and residential pool owners typically recover full costs within a short period through reduced electricity bills, ensuring a fast and reliable return on investment.
Engineered for commercial-grade reliability, this unit eliminates risks associated with open flames, electric leakage, gas explosion, and carbon monoxide poisoning common with gas or electric heaters. It is equipped with multiple safety features including overload protection, electric leakage protection, and high-temperature protection, fully complying with strict commercial safety standards and minimizing operational risks for facility operators.
The unit features an intelligent digital controller with one-key start, freely set temperature, and timed on/off functions. It automatically maintains your set pool temperature with precise control, ensuring consistent comfort without constant adjustment. Optional WiFi remote control allows you to monitor and adjust pool temperature from your smartphone, anytime and anywhere. Set it and forget it—the heat pump does the rest.
The unit is equipped with a spiral titanium tube heat exchanger that resists the erosion of chloride ions commonly found in pool water. Unlike copper or stainless steel exchangers that can corrode over time, titanium ensures stable performance and extends the service life of the unit. This makes it particularly suitable for saltwater pools and chlorinated pools, giving homeowners peace of mind.
