Imagine extending your swimming season from early March all the way through late November, with perfectly warm water on crisp spring mornings and refreshing cool water on scorching summer afternoons—this WA-12 EVI inverter pool heat pump makes that dream a reality for small & medium residential pools up to 10,000 gallons.
Unlike basic single-speed pool heaters that stall out in cold air, our advanced EVI low-temperature inverter technology delivers consistent heating performance even when outdoor temperatures drop to -13°F, eliminating the seasonal limits of traditional pool heating equipment. The dual heating & cooling function puts full temperature control in your hands, so you never have to settle for icy or overheated pool water again.
What truly sets this heat pump apart is its game-changing energy efficiency. With a peak COP rating of 13.82, it extracts far more heat from ambient air per watt of electricity used, slashing your monthly pool utility costs by up to 70% when replacing propane heaters and 40% over gas alternatives. The large silent fan keeps operation barely noticeable at just 48dB, so your backyard evenings, pet rest time, and family outdoor gatherings won’t be disrupted by loud machinery noise.
Built-in WiFi smart connectivity removes all the hassle of manual unit adjustments. Pull out your phone to toggle heating/cooling modes, set custom temperature targets, activate quiet mode for nighttime use, program auto shut-off timers, and monitor the automatic defrost cycle that maintains unbroken heat output on freezing nights. The adaptive defrost system runs on a low-maintenance 40-minute cycle with a quick 5-minute purge, no regular manual clearing required.
Designed for permanent outdoor backyard placement, the black textured cabinet features anti-UV coating to withstand years of sun exposure without degradation. The full installation package includes all essential hardware to skip extra store runs: shock-reducing rubber pads to minimize vibration transfer, a drainage joint for condensate runoff, a protective anti-UV cover for off-season storage, and a detailed step-by-step user manual. Running on standard 220-240V 60Hz household power, this pool heat pump arrives ready to install, backed by a comprehensive 3-year manufacturer warranty covering all factory defects.
