    Dual Heat Pumps on LI?

    I just did some rough calculations after reviewing my electric and NG bills. Our total electrical rate is actually $0.235/KWH, and our NG rate is $1.338/therm. If I assume the pump runs at the exact same speed, a HP cost $1.12/therm assuming 100% efficiency and a NG heater, assuming 85%...

    Dual Heat Pumps on LI?

    Thanks James, those charts are very helpful. I guess the problem is at night, even in June, the temp falls below what the pump can keep up with, so I would have to wait until morning to start being able to heat the water. Based on @1poolman1's numbers, I can only get roughly .35 deg/hr at ideal...

    Dual Heat Pumps on LI?

    Good point about the flow requirements. I have a IntelliFlo VS+SVRS Variable Speed pump, with no automation. Pool guy gave a quote on automating things with a NG heater when I first priced this out last year but it was nearly 10k for features that, although cool, don't seem really necessary...

    Dual Heat Pumps on LI?

    Thanks all. I found an interesting price comparison on energy.gov that shows HP vs NG heater cost by city and desired temperature. In NY, at 82 deg it says a HP will cost $1660 to heat w/o a cover to 82, and $3250 w/ NG, for a 1000 sq ft pool. Unfortunately mine is 2000 sq feet, so I assume I...

    Dual Heat Pumps on LI?

    Thanks for the replies. I'll have to look into all those credits James, had no idea about most of those. Not sure if they will apply or not to a swimming pool but worth a look. We have 200amp service but I'm sure I'll need to run a 2nd line to the pool equipment if we are really doing 2...

    Dual Heat Pumps on LI?

    I've been looking into installing a pool heater after using our pool for the first time last year. It's ~45-50K gallons and gets nearly full sun during the day on Long Island, NY. The pool is comfortable during the summer on sunny days (~78-80) but gets chilly after the sun sets. The curved L...

    Paver Tube Replacement w/ PVC?

    I'm not doing it for cost savings, rather the company claims they are superior to the brass anchors. I was wondering if that was true, or if they are essentially trying to save money on parts. I couldn't find a single mention of a PVC type anchor, hence my hesitation.

    Paver Tube Replacement w/ PVC?

    I need to replace my custom safety cover, and the pool company mentioned many of the existing loop-loc paver tubes are in poor condition (our first year in this house but I assume most of the anchors are ~10 years old). He mentioned they used schedule 40 PVC for their tubes and they don't seize...

    New Owner, Questions about Getting Started

    Thanks for the replies! The water didn't look good, and I definitely couldn't see the bottom of the deep end. Now it is looking clearer, hard to tell if water is still somewhat dirty or if the bottom is just that filthy. The FC held for the evening (I assume it wasn't fully circulated but it was...

    New Owner, Questions about Getting Started

    I recently moved to a house which has a 45-50K pool. I have never owned a pool so did a lot of reading on this site. Pool co opened it on Wednesday and 'shocked' it. Based on my testing w/ the TF-100 Salt my FC is 0, CYA is ~5 per a pool store test (no change on TF kit), pH is 9, Salt is...
