Gas is far more expensive than a heat pump - especially if you have to use propane. A heat pump like mine runs around $3,100 (uninstalled), while a 400K gas heater will run around $2,400 (unless you need put in a propane tank - then you need to add that cost). You'll make up the difference in price the first year.
Our pool builder used all Hayward. If I were buying my own heat pump, I would look at the AquaCal line. It is more efficient and quieter in operation than the Hayward. Hayward and Pentair, for heat pumps, are very similar in specs.
If you go to troublefreepool online you'll find more info about pools than you ever imagined!
Hope this helps!

Thank you Irvalley for the info. My solar system keeps the pool between 70-75 degrees this time of year so I'll only need to boost it by 10 degrees or so. Any installers you can recommend?
