Bro, you have a seriously underpowered heat pump if you’re only getting 3-5° out of it. I have installed Raypak crosswind I-65 heat pumps and they deliver a 10° rise in temp at 30gpm. The Raypak 144k BTU heat pump can deliver a 10° rise at 40-60gpm. Also I am in Iowa and Heat pumps are fantastic here in the summer months because of how hot it gets here.
Today I turned on my heat pump. High of 91 and low of 60. I live in AZ. Its going to get warmer over the next week. I run the heat pump from 10am to 5pm when I run the pump which is when the sun is shining and I have solar panels. Not really using the AC now so its not much cost to heat. The main reason I have this heat pump is because it is reversable. In the summertime I run it at off peak hours which is 9pm. I am able to cool my water everynight down to 82. By the time I go swimming at the end of the day the water goes up to no higher than 85 or 86. I am glad that I have this feature. Most people around me will say that the water gets to 96 to 98 in the summer and it is not refreshing and so they don't use their pool. Not the case here.
Heat is energy. When refrigerant is compressed, it increases energy, rising sensible temperature. High temp likes to occupy lower temp space. Counter flow in this instance is where the heat transfer happens between the refrigerant coil and water coil. Typically a tube in tube coil. The Warner temp is rejected to the water being circulated in the pool, and the cooler temp is rejected to the atmosphere.
How can compressing refrigerant increase energy? The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. Your statement contradicts the law of conservation “increases energy”
Soooo. South Texas. Yea or nea. I'm just looking to get in earlier at Start up. Then extend my season. So does this always run when I run my pool filter? Above ground 18ft round with middle dug out and one 57 morning cooled me out. Still hot and humid outside but the water just never got warm enough again. Help! Will this help here?
Have a 16 by 40 pool 🏊♀️ and let me tell u something … have a huge pool heater a good one and takes forever to warm the water … It’s nice when the water is warm but almost u have to leave it on all day to warm it up if is not warm outside …

Do you have a video on how to set up a cold climate pump house for semi inground pool? I’m reading the equipment needs air flow so the motor doesn’t over heat but I want to keep it from freezing in the winter so the pump can continue to heat the pool and move water. If I let the cold air in then the pump house won’t stay warm. But if I keep the pool house warm then the motor overheats. What’s the solution? Do I put the pump house under the concrete decking? Do I leave it in a tiny shed above ground? What insulation techniques do you use
I am in South Florida so heat pump looks like a great option. I also have mini split AC in my house (heat pumps). Can I harvest the heat from these units to help heating the pool? We run AC (cooling) even in the winter, and that's the time of year we would most need to heat the pool. Outside daytime temperature is 70-85 degrees on most days in the winter. I am trying to figure out the system to heat the pool only on the "cold" days and to also heat the water in the spa.
Who uses their pool when it’s below 50 degrees? It’s not a hot tub, heating the pool during the late spring to early fall would extend most people’s pool season in the cooler climates, and that’s all we’re looking for. Not to use it when it’s below 50 🥶
True. That's what I'm trying to find out. Can this be used at opening to get in quicker, and in the late summer to keep it open in South Texas until we dip below 70's (November in alot of years)
@@SoundOfYourDestiny If you’re in the warmer climates it shouldn’t take that long for the pool to warm up even if it gets below 50 at night, but yes of course you could to help the process. The video was saying using the heat up during the winter, winters here in New York that would be like using it like a hot tub. That’s all I was saying.
My fiberglass pool shell has a hot tub section. The pool heater can be used to either heat the pool or the hot tub. We definitely use the hot tub portion in the winter, so a heat pump likely wouldn’t be a good fit.
I have an indoor, inground pool south of chicago. The gas heater I use is extremely expensive to operate. I don't plan to use it in winter, just an extended summer, starting in spring and running into fall. I have asked Raypak about installing it in the basement and replace their heater/boiler. They say not possible. Even installing it in the room with the pool would be great. It would remove the overheated humid air to heat the water. In there I would still have to winterize it, just as outdoors, to prevent freezing of water in the heater and plumbing. Any answers?
We have an 8,000 gallon 18 ft above ground pool. I bought a heat pump and when it was still in the 90's outside, our water was 78 (loads of shade trees all around). I connected the heat pump and within 2 days we had the water at 88. Eventually peaked at 90. It was WONDERFUL. Then we got our first cool front and temps were 70's during the day and low 60s at night. Water plunged down to 76 very fast even with heat pump running. Is that normal? Also, would it do any good to use a space heater in the event that we were going to have friends over for a weekend as a short term measure to try and help give the heat pump some hot air to work with?

I don’t know if anyone answered your question about “ replacing Freon “ . Freon is in a sealed system… if there isn’t a leak , you don’t need to change it .
I payed 2916kr (318 dollar) per month for my 9kW electrical pool heater and I now pay 78 dollar for my POOL HEAT PUMP. My pool is 60m3, or about 60,000L. I live in a colder part of the world my pool season is may-sept, I can extend if I combine heaters.

Even here though when the temps drop below 50 it doesn't keep the pool nice and toasty.
I live in Alabama. Our winters are typically in the 40s, rarely in the 30s, but can get in the 30s. I have a 18,000 gallon pool with a 6 seater hot tub being built.

I was hoping to have one heater to operate both and I know heat pump would save a bunch of money in energy cost. Thanks for any feedback.
16000 gallon and it’s hard to say how much the heater adds because it’s always turned on. It does run that much once the water is up to temperature.

"when temperatures are cooler outside".... IMMEDIATE DISLIKE FROM ME! A Temperatures can NOT be 'warm' or 'cold' or 'cool'. The WEATHER can be warm, or cold or cool and the temperature can be LOW or HIGH.
