The verdict is in. I had an electrician here on Friday. His quote was astronomical ($1,700). I called an electrician who worked on my home with the AC units. Explained the situation and he is at around $700-$900 max, approximately 50% of the pricing. Explained that I needed a quad at the fuse panel, and that outside the wire would need to be 18" deep and in a conduit. He has worked on these before. The salt cell can be wired to the existing pool pump electricity. This is the last step, so I have time.
I also called the manufacturer who produces the heat pump. The unit produces 25.57 amps at 230 volts. Based on my calculations, if the heat pump is on 12 hours per day for 30 days a month, the total cost would be $343.83. I was with someone yesterday, who on average spent $640 a month in gas charges to heat up the pool. We did not get into specifics of size or temperature, etc., so the calculations could be off. It sure appears that the heat pumps are efficient. The only downside is the time it takes to keep the water at temperature. I doubt the unit will stay on for 12 hours a day. I was also told that there is a 4.8 degree difference of coming out of the unit than coming in from the pool.
Next year, I will report the total cost (approximate) and temperature of water. If everything goes smoothly, then the month of September will be interesting to determine the cost at the end of the season. Will not keep pool open past September. I doubt the unit will run for 12 hours. In addition, the cost to turn the pump on for 12 hours is $4 per day. I could turn the pump on at 8 p.m. the evening prior and run through the night to heat up the pool. I was told that a solar blanket would reduce electricity costs about 50%, based on cool nights which dip in the upper 60's to lower 70's.
Here is the cost:
Heat pump $2,800
Permits $200
Electrician $900 Max
Plumbing $500 Max
Salt Cell $1,500
Pad $50
Posts, etc. $50
Total $6,000.
If I went with a gas heater, the installation cost would roughly be the same. The heater is less expensive, but the gas line would run about $2,500. Hope this helps!
