These things are amazing! I installed the FH055 on our above ground 7000 gal pool and it will heat the pool to basically whatever temperature we want. Installation is straight forward (with the conversion kit to go from Intex pump to the heat pump (1 1/2" PVC purchased from FibroPool). I was skeptical at first because the INTEX pump is rather small; but, the flow it puts out is more than enough for the heat pump. {Note: I did bypass the restrictive inlet valve on the pool. I shut this valve and ran 1 1/2" PVC over the top of the pool rail and down into the pool (~4" deep). I also put an elbow on the outlet and turned it so the water causes a swirling motion in the pool. This helps to deposit whatever solids are in the pool in concentrated areas so that the pool is much easier to clean.

We live in the Pacific Northwest on the east side of the mountains; so, our environment is basically desert. When I first hooked up the heat pump, it was in the low 80's (deg F) outside and it was raising the pool temperature 2 degrees per hour. The temperature change across the heat pump (delta T; outlet temperature minus inlet temperaturte) was 2 deg as well. As the air temperature heated up, the heater became more efficient and the temperature across the heat pump was 4 degrees.

Now my wife will enjoy her pool from May until likely November.

The controls are straight forward and easy to operate (read the manual).

Customer support at FibroPool is exemplary and I would not hesitate to…
