How to choose

Match BTU to pool size

BTU is the heat output figure for a heat pump. The MICOE and POOLTOHOT each give 58,000 BTU, the NATURAQUELL gives 55,000 BTU and the VEVOR gives 70,730 BTU. Compare that figure with the pool size each maker gives: 16,500 gallons for the MICOE, 16,000 gallons for the NATURAQUELL, 11887–19812 gallons for the VEVOR and 21,000 gallons for the POOLTOHOT. Pick the gallon figure that covers your pool.

What inverter control does

An inverter system adjusts output as the pool approaches the set temperature, instead of simple on-off cycling. The NATURAQUELL uses a full inverter system with a COP up to 16.00, the VEVOR uses a full DC inverter compressor with a COP of 15.99–6.93, and the POOLTOHOT uses full DC variable frequency tech with a COP of 15.8. COP is an efficiency figure: compare COP figures only where two picks both give one.

Controls, noise and upkeep

Controls differ across these picks. The MICOE has a mobile app and an onboard digital control panel. The NATURAQUELL has the Smart Life app and a touch panel with timers. The VEVOR has WiFi app control with silent mode and timers, and the POOLTOHOT has WiFi app control with a touch panel.
