The AQUASTRONG HEX035 is a high-performance inverter pool heat pump designed for above-ground and inground pools up to 9,000 gallons. It excels at both heating water from 47°F to 104°F and cooling from 47°F to 83°F, making it ideal for pool owners in variable climates who want to stretch their swimming season into cooler months without skyrocketing energy costs. With 35,000 BTU output and a flow rate of 20 GPM, it suits medium-sized residential pools perfectly.
Standout features include full DC inverter technology delivering a top-tier 15.8 COP for up to 70% energy savings over traditional electric heaters and 40% better than gas. Users report rapid temperature rises, maintaining upper 80s°F even during cold snaps, with the WiFi app enabling remote scheduling and monitoring. Real-world feedback highlights its efficiency on 15,000-gallon pools, quick setup, and strong performance in chilly conditions like New Hampshire autumns.
Build quality impresses with a compact 39x17x26-inch footprint, cast iron durability, and weather-resistant design. At just 48dB, its variable-speed fan is quieter than older units, and auto-defrost cycles every 40 minutes ensure seamless winter operation. Installation is user-friendly with included adapters for various hoses and PVC, though wiring a 115V/25A circuit may require an electrician. The app is generally reliable after initial setup, with responsive support noted by most.
Drawbacks include the unit's 117-pound weight, necessitating team lifting, and rare complaints of error codes or app glitches that support sometimes struggles to resolve quickly. Despite these, positive experiences dominate, with many praising lower bills and extended pool use.
Overall, the HEX035 delivers premium efficiency and convenience at a competitive price, earning its top rank in pool heat pumps. It's a smart buy for efficiency-focused owners ready for basic electrical prep, transforming seasonal pools into year-round retreats.
