I am interested in adding this heat pump to my abive ground saltwater pool. I currently have a 1.5 hp pump.
Will I need to have a stronger pump when I add the heat pump.
Does it matter where in the water circuit I put the heat pump (before or after the sand filter; before or after the chlorine generator)
Hello Gbaron - We’d be glad to assist you.
You would not need a stronger pump for the heat pump. A 1.5HP pump will be more than enough to meet the minimum flow rates.
The heat pump would be installed after the filter and before the chlorinator.
Thank you. Here’s another question. Which company issues the logest warranty for heat pumps? I’m looking for about 120-150k BTU.
Most of the warranties among the major manufacturers are similar. The Raypak Heat Pumps seem to have a slight edge. Their warranty covers two years labor, seven years for parts and ten years on the titanium tube. They require that a licensed professional install the heat pump. Otherwise the warranty is voided.
I have an 18 x 30 ft. above ground pool with about 14,000 gallons of water. I want to be able to raise the temperature 10 degrees. It looks like I will probably go with the AquaCal TropiCal line. Which size will I need? Thank you.
We’ll need to know a couple factors before we can recommend a heat pump size. What is the closest major city to your location? Does the pool receive direct sunlight? Will you be using a solar blanket? What is the desired water temperature?
Thanks for your help. I live near Charlotte, NC. The pool gets about 9 hours of direct sunlight in the summer. I don’t use a solar blanket because my wife doesn’t like unrolling it or taking it off. Our goal is 86 - 89 degree water and the cooolest we will swim is ambient temperature of 78, so the maximum increase of temp we’re after is 10 degrees.
Based on the pool size and other factors, we would recommend the AquaCal Tropical 141k btu heat pump.
The 90k would probably work but it would be cutting it close. Since the price is very close, the 141k is the way to go.
I have ordered the heat pump from you. Thanks. Since I am retrofitting the pool, it will be easiest if I buy a dedicated pump just for the heat pump. I want to keep the pressure low enough that I don’t have to worry about a pressure regulator, and the User Manual says that the cutoff is 70 gpm. It’s going to sit right next to the pool, so the pipe distance will be fairly short. Can I manage with a 3/4 horsepower pump?
Thank you for placing an order with Inyo! A 3/4HP would be sufficient. However, you could plumb in a bypass around the heat pump and use the current pool pump. This way you could divert some of the water around the heat pump if the GPM is too high.
The way my pool is set up now, I’d have to put in 5 elbows to accomodate the heat pump, which would lower my flow through the chlorine generator or I’d have to worry about actually alternating the flow through a bypass valve manually every day. It’ll be easier to have a dedicated pump on a timer.
I purchased a Hayword HP21404T and it’s installed and working fine. The filter is on a timer but the heat pump is not so I am going out and manually turning it on and shutting it off each day. The Heat Pump has flow sensor that shuts it off and changes the display window to “flo” (not sure if it shuts off only the heating elements or the entire pump) whenever the filter stops sending water through it. My question is: Given that my timer turns the filter on every morning and runs for 10 hours per day, would I damage the heat pump in any way if I don’t manually switch it off each night? Also if I am able to leave it in the on position every night, is the heat pump still pulling a lot of electric when it’s not heating or is it only pulling what it needs for the digital display panel and sensor?
Hi Florencio,
The way my heat pump works and I believe it is the same as yours is as follows…
My time controls power on and off my pump and the heat pump will only operate when the pump is powered on as the heat pump has a flow sensor that indicates when water is flowing through the heat pump.
I set my temp. on my heat pump to 85 degrees.
If the pool pump is on and the water temp is below 85 degrees then the heat pump will kick on.
If the pool pump is on and the water temp is above 85 degrees then the heat pump will no kick on.
If the pool pump is not on then the heat pump will not kick on regardless of water temp.
If the heat pump is not on then you are not spending any money to operate the heat pump.
