What size pool will this heat pump handle?

It is rated for pools of about 11,900 to 19,800 gallons (45–75 m³). Larger pools will heat more slowly or struggle to hold temperature in cool weather.

How is an inverter heat pump different from a standard one?

A DC inverter compressor ramps its speed up and down to match demand instead of running full-on then off. That gives steadier water temperature, lower startup current and quieter operation than fixed-speed units.

What flow rate does it need?

At least 20 GPM through the unit. Check your pump's flow at the filter and heater loop before buying; undersized flow is the most common reason these units underperform.

What power supply does it need?

AC 208–230V, 60Hz, single phase. A dedicated circuit sized for the unit's running and startup current is needed, so plan on an electrician for the hookup.

Can I return it if it doesn't fit my pool?

No. It is sold non-cancelable and non-returnable, so confirm pool volume, flow rate and electrical capacity before ordering.

Does it heat and cool the pool?

It is a heat pump built for heating pool water. Confirm with the seller whether this model also reverses to chill water if cooling matters to you.

Our take on the 70,730 BTU Electric Pool Heat Pump with DC Inverter

This is an inverter pool heat pump rated at 70,730 BTU, running on standard 208–230V single-phase power. The DC inverter compressor varies its speed instead of switching on and off at full tilt, which is the main difference from fixed-speed heat pumps and is what keeps pool temperature steadier and running noise lower. It is sized for pools of roughly 11,900 to 19,800 gallons (45–75 m³) and needs at least 20 GPM of flow through it. That makes it a fit for mid-size in-ground pools and owners who want quieter, more even heating than a basic on/off unit provides.

Pros

DC inverter compressor modulates speed for steadier water temperature
Quieter and gentler on the power draw than fixed-speed units
Handles pools up to about 19,800 gallons
Runs on common 208–230V single-phase household power
Works with standard pool plumbing at 20 GPM minimum flow

Cons

Sold non-cancelable and non-returnable, so sizing mistakes are costly
Needs a pump that delivers at least 20 GPM or it won't run properly
Inlet pressure must stay within 43.5–72.5 PSI
Installation typically needs an electrician and a pool tech
Inverter boards and compressors are costly to repair out of warranty

About the 70,730 BTU Electric Pool Heat Pump with DC Inverter

This is an electric pool heat pump with a DC inverter compressor. It uses R32 refrigerant to draw heat from the surrounding air and transfer it to the pool water. Heating capacity ranges from 14.23 to 70.73 kBTU, with a COP of 6.93 to 15.99.

The unit has a salt- and chlorine-resistant spiral titanium heat exchanger and a pure copper evaporator. A low-noise brushless fan and multiple noise-reduction technologies keep operating noise as low as 50 dB. It works in ambient temperatures from 5 to 109°F (-15 to 43°C). Protections include high- and low-pressure protection, water-flow protection and automatic defrost.

Built-in WiFi, OTA updates and an app let you control the heat pump from a smartphone. You can adjust heating, cooling, silent mode, water temperature and timers. It is designed for pools of 11,887 to 19,812 gallons and is suitable for homes, hotels, resorts and spas.
