I would like to know how much money I will save using a heat pump vs gas considering the outlay of 3000 for the heat pimp. Thanks

The bolded part above is the key to your success
bk406 said:At 50,000 BTU and a pool of say 20,000 gallons, you cant put enough heat in one that size to overcome the heat loss late, or early in the season. Even if you have a 120,000 BTU heat pump, at 40 degrees ambient, you wont get anywhere near 120,000 BTU (or even a fraction of the 50,000 BTU for that matter. So, you still cant put enough heat in to compensate for the loss. If you like your water at 85 plus like me, its going to be tough to make that happen on a normal size pool (>14000-15000 gallons) with 45-50 degree nights and short days. Even if you could, you would need to run the HP and the filter pump 24/7 to try and maintain that temp. At 0.09-10 cents per k/w hour or greater, the savings a heat pump might give you over gas are now negated.

A heat pump "maintains" the pool temperature more efficiently. To allow the water temperature to drop well below 80 degrees will force the heat pump to work much longer. I agree with you that heat pump manufacturers are selling their products with an overblown "efficiency" rating then transferring it over to "savings" for the consumer. You make some very valid points. Not all consumers need their water temps "maintained" throughout the day.bk406 said:I got nothing against a heat pump, i have one. But the only gas i have is propane, which its expensive. So i have a HP too. They do work quite well, but on the ends of the season, not so much. My only gripe with them really is how they are sold as a panecia to all your heating cost issues and none of the downside is presented. As far as those calculators for heating cost go, notice they all are put out, for the most part, by the heat pump folks. And, they do a lousy job, IMO taking into account how one uses the pool.
