We were discussing heater/chillers with our PB and he said that if we wanted to swim in the winter, it would be cheaper to keep it heated by a chiller/heater system because they are electric and therefore much cheaper to run. He said they aren't good for heating up a pool very quickly but they are good for maintaining a certain temperate and that the difference in utility costs could be several hundred dollars if a pool was heated for an entire month. We have a standard spa pool heater in our new pool (Jandy), 0and thought we would add a chiller if we needed to cool the pool down, but we hadn't thought about using the chiller for its heating capabilities. So my questions are:
1. If you have one, do you use it to heat your pool in the fall/winter/spring and if so, is it economical to heat your pool with it?
2. Do you use it for the chiller part and how expensive is it to run that?
3. How much did it cost you to add this to your pool equipment?
