100kBTU electric inverter heat pump pool heater/cooler

Bought and installed it last year, works great with wifi app control but it takes a good 24 hours to heat up our 20,000 gallon inground pool. It would be a better fit for a smaller size pool. It has the inverter technology which is more energy efficient. Also has titanium heat exchanger so its durable and long lasting.
