The gas heater I'm looking at is $1380 for Jandy 325K btu. The heat pumps I have priced are all over $3500+. Gas line install is only $300 & natural gas in our area is a pretty good value. I really considered the heat pump route, especially to cool the pool in July & Aug, but the difference in $ would take MANY years to be offset by the heat pumps better efficency. Thanks
