We received our pool docs back yesterday to submit to the HOA and there was a mistake so I'm using this time to ask questions about heat pumps vs gas. We live north of St. Augustine and were going to do a heat pump as several friends with gas for their spas admit to not wanting to re-fill them due to the cost. We will have the I-Link setup for our iPhones to pre-heat the spa etc. Anyone in our region have any opinions on this? Gas may be cheaper initially (except for tank purchase etc) but heat pump does take longer. Our spa will be 7 ft. Heat pump cam heat pool but I doubt we'd use that feature a lot except during school holidays...it's worth any price to keep our three seven year olds swimming and having fun in the pool!!! Thanks for your input, I love this forum!!!!
