  • Heating speed is very fast
What is amazing is how quick it heated up my pool in just 4 hours. After I got it started the water was 64 degrees. 4 hours later...79!! That is incredible. The unit has a COP of 16.13 which is super high. So I can heat the pool quicker and cheaper.This cools and heats the water. It has a very nice crisp touch screen display on the unit and also has a easy app to set temps and such from anywhere. ... show more
