This heat pump is labeled for an in-ground pool. Can it also be used for an above ground pool?

Yes, this heat pump can be used with an above ground pool. You just have to ensure that it is wired correctly. It needs a 60 amp dedicated circuit breaker and has to be wired directly to the circuit breaker box.

Old heater was rusted out

Written on 6/17/2019 by Guest

I replaced a heater with the same model, to make it easy. I took a picture of the old wiring, and then drained it, and removed the heater with a dolly. Then I just rewired and plumbed it the same.

Heat exchanger corosion, in Haywood Pool Heat Exchanger

Written on 9/21/2018 by Guest

1. Went to Inyos Pool website, and found replacement Hayward Pro Heat Pump 110,000 BTU. Ordered, and delivered.
2. Watched YouTube video on how to hook up heat pump.
3. Took pictures of plumbing and electrical of existing heat pump, in place.
4. Disconnected (turned off) circuit breaker for heat pump. Opened GoldlinevController cover panel and disconnected heater control wiring from Goldline controller panel.
5. Disconnected PVC 2 1/2” inlet and outlet pipes by cutting (as close as possible to heat pump flanges).
6. Disconnected electric wires from circuit breaker box (opened up breaker box, took inside picture, disconnected and labeled each wire). Then had to disconnect wiring from the heat pump (but did not yet reconnect wire to circuit breaker box). Took picture before disconnect.
7. Disconnected Goldline Controller connecting wire from old heat pump.
8. Removed heat pump from concrete pad.
9. Moved new heat pump to concrete pad, about 3” to 4” closer to cut piping, to connect to cut pipes. New replacement heat pump was same model (newer version) so pipes lined up perfectly.
10. Inserted pipes into inlet and outlet flanges. This was a bit difficult, as I originally put in a bypass pipe and valve between inlet and outlet, so the inlet and outlet pipes were pretty rigid, but since they were aligned to flanges, was able to get them inserted. Used PVC glue on interior of flanges and circumference of pipes before inserting.
11. Connected heat pump wiring to bottom of heat pump electrical, using previous picture as guide.
12. Connected other end of electrical to opened circuit breaker.
13 Closed circuit breaker cover.
14. Connected control wiring to Goldline Controller, and to new heat pump.
15. Turned on circuit breaker.
16. New Hayward Heat Pump LED screen lit up.
17. Set temperature to 85F.
18. Heat pump began operating.
19. Hayward Controller settings for heat pump were not changed from prior (old heat pump) settings.
20. In hindsight, realized I only needed to disconnect electric and controller wires at the heat pump, not the circuit breaker and Goldline Controller.

Now I want to see if I can buy a replacement heat exchanger for the old heat pump, as the compressor motor and everything seemed to be working.

I installed the heat pump without a problem. Very easy to install and connect. I literally pushed a button and it started and worked just fine.

Installation - leveled the ground, laid some concrete pavers, set the heat pump, plumbed it and wired it. Everything was great except two noticeable things. One was that I installed the heat pump lower than the pool surface and the manual mentioned I might need to adjust the pressure switch, however, it appears they changed the design and it didn't match the picture in he manual. It turned out it wasn't an issue at all. The other was that I would have figured there to be a more secure wire connection. Usually when making an electrical connection there is a connector to hold the wire securely to the unit. In my case there wasn't one. Not an issue for me - there were two holes and the one they wanted me to use (as indicated by location and some type of fitting) was hindered by "stuff" below it so I used the other hole and added my own secure connector. Also, the lugs are not sized for wire size 6AWG, but that just happened to be the wire I had available and you can get by with wire size 8AWG so it isn't an issue. I posted 4-8 hours of time, but it depends on how much prep you need to do. The actual installation was ~2hours, but I had a few more hours into it to prep the location and pull wire from the house and fit the PVC piping so that adds to my time that may not be the case for somebody else.

Even with a solar cover oor pill was still to cold

Written on 3/4/2018 by Guest

We purchased this heat pump after reading all the reviews on at least 8 others. This was the best one and inyo had the best price by almost$400. Ordering and shipping went flawless. After making a concrete brick platform for it, my buddy helped me install it. By far the best thin ng I did for my pool.

New heat pump

Written on 1/13/2017 by Guest

I bought this heat pump, Hayward Heat Pro Heat Pump 110,000 BTU, and saved a lot. It was delivered within a few days. The pump is working like a charm, my pool is now useable all year. In winter I set it to 85F and everyone in the family loves it.
