Heating, cooling, and defrost
Heating and cooling modes let a unit warm water in cooler weather and cool it when heat builds, and each pick here has both modes. Heating ranges run from 46 to 104 degrees on the MICOE and GRAT, from 47 to 109 degrees on the POOLTOHOT, and the VEVOR operates from 5 to 109 degrees.
App control, covers, and installation
App control on each pick here adjusts temperature from a phone, and the GRAT and Oibath add Bluetooth alongside WiFi. Keep the pool covered in cooler seasons to hold heat, and run the POOLTOHOT heater 24 hours in advance with the pool covered. The POOLTOHOT must be installed by a certified electrician, so plan that step before the unit arrives.
