I am building a 42K gallon pool with 1000 sq ft surface area in central texas. I want to heat the pool with the idea of extending the swim season by about six weeks at both the beginning and end of the year. During this time the air temp is about 80 but the water may be 60 - 70. I would also like to be able to cool the water in the brutal summer months.
Due to the size and surface area of the pool none of the PBs or pool shops I have spoke with can agree on how to do it except that I should forget propane/gas since I am not wealthy. Some say go with solar heat (I have southwest exposure and room for only about 10 4x12 panels) while others say a heat pump will work, while others say I will need two heat pumps. I recall one post on this forum that stated solar wouldn't work in the Austin, Texas due to lack of sunshine but would work in New Mexico. ??? It seems like we get plenty of sunshine as a general rule, so I am confused. I figure I better consult those with experience. Thanks to everyone who replies; it's great to get real world advice instead of a PB's opinion about what product gives him the best profit potential.
Especially if you live in central Texas, please relate any experience you may have on heating/cooling your pool.
