What pool size is the 35,000 BTU model for?

The line covers pools from about 7,000 to 26,000 gallons, but capacity depends on climate and whether the pool is covered. For a large or exposed pool, size up rather than down.

Does it really cool as well as heat?

Yes. It cools water from 47–83°F and heats from 47–104°F, so it can take the edge off a hot pool as well as extend the season.

The variable-frequency compressor is quoted at 55 dB, roughly normal conversation level. Owners generally describe it as quiet.

What connections does it need?

The kit includes 1.25" and 1.5" hose adapters, a 1.5" adapter conversion kit and a 1.5" PVC pipe converter. Match the inlet and outlet correctly or it will not heat.

Will it work in cold weather?

Auto-defrost cycles every 40 minutes keep it running in cold spells, but output drops as air temperature falls. It is not a replacement for a heater built for deep winter.

Can I control it from my phone?

Yes. The app and panel let you set temperature, schedule heating and track energy use remotely.

About the AquaStrong 35,000 BTU Pool Heat Pump

The AquaStrong 35,000 BTU Pool Heat Pump heats and cools pool water. It heats from 47 to 104°F and cools from 47 to 83°F, which lets you keep the water at a set temperature through cooler seasons. This model is sized for pools up to 9,000 gallons.

It uses a full DC variable frequency inverter rated at 15.8 COP. The inverter adjusts power in real time, and the unit runs at 55 dB. An auto-defrost system starts a cycle every 40 minutes and finishes it in about 5 minutes, so heating continues in cold weather.

You can set temperatures, track energy use and program heating schedules from the control panel or the app. The heat exchanger is 100% titanium and resists chlorine and salt water. Internal screws, brackets and key components are rust-proof.
