I've had this model installed for heating my 16 X 30, 9' deep at one end pool since October 2014. It has been a very reliable, effective operating Heat Pump. Don't believe Heat Siphon still makes this model.

My family and I would like to thank you again for the exceptional service and product. To all of those on the fence about ordering from Pool Heat Pumps, please read through our testimonial. Our family installed a 22’x42’ Doughbougy Autumn Breeze last summer. We live in Central British Columbia, Canada. While still quite far up North, our climate still gets quite warm over the summer months. Daytime highs are typically 90-100 degrees in July and August with overnight lows in the low 50’s. April and May are much cooler as is September and October.

Last summer we kept our pool covered when it wasn’t in use. The warmest temperatures we saw the water climb to was in the low to mid 80’s. For the most part, the temperatures always hovered around the 76 degree mark which felt a little cold to the adults but was fine for the kids. We were looking to extend our swim season a month or so earlier and later with some form of heat. We had no interest in quickly bringing the pool up to temperature and wanted a source that could maintain our water in the mid 80’s.

After several months of research and questions we stumbled upon Asa Strong at Pool Heat Pumps. He answered all of our questions thoroughly and promptly and took the time to explain the facts about heating your pool with a heat pump. In our current economic times of corporate distrust both my wife and I had an overwhelming sense that we were being taken care of right from the beginning………….our feelings were later confirmed.

I was originally set on a Rheem 170,000 BTU commercial model. Asa explained the pro’s and con’s and we ended up going with a Heat Siphon Z700HP. We came to an agreement on price including all taxes, duties, etc shipped to our door. The price was several hundred dollars less than any other company including the shipping.

Unfortunately, the Heat Pump was only shipped to the local terminal. The company wanted an additional fee paid to have it delivered to the house. We called Asa promptly and explained the situation. To his credit he arranged local delivery and paid for it all out of his pocket. He told us he would honor the agreed upon price despite the shipping mix up.

The Heat Pump arrived in immaculate condition. We thoroughly inspected it before signing for the delivery. The installation was completed in a little over two hours by myself and an electrician. We installed a bypass due to the 160 GPM output of our Hayward variable speed pump on maximum flow.

The air temperature was 50 degrees and the pool temperature 46 degrees three weeks ago when the heat pump was first turned on. During the first day the water rose to 58 degrees. Each evening the heat pump would turn off as the air temperature cooled below 45 degrees. Despite the pool losing 4-6 degrees each night we were able to bring the pool up to 76 degrees after four days. This was our average temperature last summer and it was only the second week in April.

The temperature then warmed into the 60’s for the following week. Our pool rose to 88 degrees within two more additional days. The water temperature has stayed at 88 degrees for the last three weeks and we have been in the pool everyday. We were shocked at how quickly and efficiently the Heat Siphon brought the temperature up. It runs for approximately 3-4 hours each afternoon to maintain the 88-90 degree temperature despite the outside air temperature averaging 60-70 each afternoon with the overnight lows dipping to 50 degrees.

I have no doubt we would be able to bring the pool into the mid 90’s if we wanted to. We have had zero problems with the heat pump since the installation and it runs extremely quiet. The water coming out is 8-12 degrees warmer than the pool depending on the flow rate set on our pump. There was a great deal of condensation the first day which I mistook for a leak. We tested the water for chlorine and it wasn’t present confirming it was just condensation.

Again, I can’t say how pleased we are with the product and the service Asa provided. He is clearly a cut above the rest and personally took care of us. Our seven year old son is in the pool everyday after school enjoying the warm water with us. The ease of installation, performance and price are all second to none. We would highly recommend Asa Strong and Pool Heat Pumps to any of our friends and family.

Please copy and paste our testimonial and the pictures you choose below onto your website. We are 110% thrilled with the heat pump and the service you provided us. Just for fun, we took the pool up to 96 degrees ast week!! It was 55 and raining outside and the steam was just pouring out of it :) Thanks again for all your help and the amazing service.

You are truly a cut above the rest.

I needed a heat pump that could produce 140,000 BTU's and am very satisfied with the performance.

The Heat Siphon Z700 heat pump arrived, and I have it installed. I poured a concrete pad outside the garage for it, then drilled two 3 1/2" holes through the wall and put ABS pipe in them as a conduit for the 2" flexible PVC I used for the heat pump piping. I am enclosing photos of the install.

I put the unit on a platform of 1 ½” plywood, on casters for ease of moving, with rubber matting on the top of the platform and around the edges as skirting so critters won’t live underneath. The unit has to sit at about 45 degrees to the wall, which made planning the piping a little more complicated. In the garage, I had to work around the existing wiring conduits, so it is not as neat as I would have liked if I were doing it from scratch. However, the entire original pool installation was not well done, as I indicated in my original email.

The instructions do say not to have a bypass, but I put one in for better ease of draining the pipes inside the garage at start of winter. Since I am the only one who deals with this, I have no concerns with it. We used to have to run the geothermal all night to get the pool up a couple of degrees, and it could almost never get it up to more than about 80 except in really hot weather. When I finished the install on this unit, I held my breath and threw the breaker. The unit started up, and at that time, the pool water was about 74.

We went out for a few hours, and when we came back, the unit was off. I thought it had shorted out or something, but no, it had already gotten the pool up to 86. 74 to 86 degrees in about 5 hours! My son had his 7th birthday last weekend, and we had eleven 7 year old boys in the pool. The day was a bit cool, so I turned the heater up to 88 and no problem at all! After several years of cool pool and the kids (and wife) going constantly from pool to hot tub and back again, we finally have a very efficient pool heater which can do the job in no time flat!

Thanks very much. Regards

Thank you very much for all your expert help with our heat pump installation. The pump works great and looks much better than our old gas heater. You guys run a truly great service. I would recommend you to anyone. We are very happy with Heat Siphon Z700HP heat pump.

Our old gas heater broke down so I started to look for an alternative. I was never very happy with the cost of heating the pool with gas. I did a lot of research online and I found your website.

The pump arrived in perfect shape as advertised. I thought I would have to pay someone a lot of money to have it installed but after some research, I realized that I could do it myself. I already had a dedicated 220v breaker box by the pool pumps so wiring was very straight forward after a trip to home depot. The heat pump runs fairly quietly, it is not any louder than my air conditioner. It is certainly not as fast in heating the pool and especially the hot tub but with little planning it is not a big deal.

My electric bill is higher but my gas bill is much lower so I am looking forward to the savings all summer. Once again, thank you for great service.
