This is the 2nd heat pump I’ve purchased from pool heat I purchased my first on about 10 years ago with Asa’s patient help and guidance. It worked fantastic and was super happy. Fast forward 10 years and admittedly poor pool maintenance practices resulting in winter damage to my heat pump putting me in the market for a new one and there was no question that I would come back to Asa and pool heat for a replacement. Asa is so friendly, responsive and helpful. He gave me my best options for a new heat pump. Again patiently answered all my questions and got my heat pump here VERY quickly.

I got the Gulfstream HE125. It is great! Quiet and efficient. I had an issue with the display panel initially but contacted gulfstream and they sent me a replacement right away. I’m very happy with my new heat pump and with my experience with pool heat If I’m ever in need of another heat pump, this is where I’ll get it from.

This is an excellent company to do business with. My Gulfstream heatpump works as advertised. I love it!!

The heat pump is great! Actually exceeds our expectations. Exactly as described. It heats our 16 x 32 above ground pool to where ever we set the thermostat and it heats it up fast. Im so glad we purchased this pump.
Weather patterns have become pretty erratic here in Ohio. June and July are beautiful for swimming but it gets down into the sixties in August, and last August it regularly got down in the forties. I'm SO glad I got the heat pump this year! Last year I might as well have closed on July 31st; this year I'm shooting for October 1st.
From initial purchase at to he local installation in New Hampshire by Daigle Pools, my wife and I had a great experience considering this is our 1st in ground pool. Expert services from helped us select the right size equipment for the pool. Delivery was prompted and pump was expertly shipped (one of my biggest concerns when ordering). Daigle Pools, Londonderry, NH were fantastic - they didn't pressure me to buy the equipment from them and also gave solid advice on heating equipment - for this, they will are my only go to Pool Company in NH I will go too. They setup the equipment and opened pool - they will be coming back for maintenance and the closing. Excellent company - working with Jim was a breeze. My family is excited to extend the New England pool season.
The entire purchase experience was A+++++. Great Product at a fantastic price and the service was absolutely top notch. Would highly recommend.

Asa, The heater is up and running and I performed 2 separate tests. The first test was with the solar cover on. The temperature increase from 83 degrees to 86 degrees in approximately 3 hours, maybe a few minutes longer. This test, I did not track any temperature, humidity, wind speed, etc. This was done at a starting time of 11 a.m. about 4 days before the second test. The second test, which was performed on August 25th, 2017 started at 8 a.m. in the morning, and ended exactly at 2:22 p.m. Ironically, I went outside to check on the temperature of the water and the heat pump shut off at one degree higher than set temperature. The heater never turned back on for the remainder of the day. Easy to follow as the unit is outside my office window at home. Please note that this test was performed without a solar cover. Below, you will find a detailed spreadsheet tracking temperature increase of water every 30 minutes. The other information was obtained from an internet search. The cost of electricity is based on rates in Monmouth County, New Jersey.

The heater has also been used several times in the month of September. The water has always been maintained at 85 degrees. The filter shuts off around 7 p.m. In the morning, and without any solar cover during the evening, the starting temperature has been around 82 degrees. The pool water temperature was back up to 85 degrees within 4 hours. It appears that the higher the starting temperature, the water will heat up in a shorter time. Therefore, it is best to keep the heater on at all times. I can easily turn on pump/heater at 6 a.m., and by 12 p.m. have the pool back up to temperature. I am really happy with the unit and as the season ends in NJ, I will have to wait until 2018 before real testing and true cost of electricity can be determined.

I was close to purchasing a different brand based on other sellers recommendations until I spoke with Asa at about Gulfstream. This is a superb unit and I am very impressed with all aspects. It was super effective in raising the temp of the 24,000 gallon pool from 79 deg to 85 deg in about 15 hours. Then, I took it up to 89 deg the next day to see what it would do. Again, it got it there quickly. We are in North Carolina and the ambient air temp was 80 deg that weekend. It is easily maintaining the temp at 89 deg and I don’t even notice it running very much. The unit is very quiet and looks great. I think the plastic structure will allow this unit to last a long time.

Thanks for the great recommendation. I would purchase from you again and I have already recommended your company to many others.
Hi Asa, The heat pump arrived on Thursday. Got it connected on Saturday and was swimming today. This is the earliest we have been able to use our pool in a very long time, maybe ever.
I fired up the heat pump yesterday for the first time. In the morning the water temp was 63. By the afternoon it was 81! Today it it reached the goal temp of 85. I can't tell you enough how thrilled I am with it! It is EXACTLY as described and you were so unbelievably helpful throughout the entire process. Please feel free to share this review on your website.
