Features

  • CLEAN AND GREEN: The FH255 is powered by clean electricity, reducing the harmful environmental effects and cost of traditional heaters that use natural gas or propane. Our pumps instead move heat from the air into the water, which saves you money and is a breeze to maintain
  • COMPATIBLE WITH: In ground pools up to 10,000 gallons and above ground pools up to 21 foot round or 15 by 30 foot oval. As with all heat pumps, we recommend using in a humid climate down to 50 degrees for best performance. Dry climates are better served by a traditional gas heater
  • HIGH EFFICIENCY: Utilizing high-pressure differential compressors and titanium heat exchangers, FibroPool heat pumps are meticulously designed to be the most energy efficient in their class. You can rest comfortably knowing your family will enjoy years of late season swimming without feeling a squeeze on your electric bill
  • RUGGED DESIGN: Enamel-coated steel chassis is designed to withstand outdoor elements season after season. Slim profile measures just 16"x40"x24", offering a wide range of mounting options. Conveniently installs with included 1 1/2 inch compression fittings
  • EASY OPERATION: Digital control panel with an easy-to-read display offers convenient temperature setting and monitoring. Optional extension cable allows you to mount the control panel in a location that works best for you

  • Proven results --- helps maintain heat.
I don’t think I’ve ever reviewed very much on Amazon, but I figured I’d place a review in for the Fibropool FH055. Tons of research and I couldn’t find very much information on the performance of heat pumps in my area. I’m in the northern California, Sacramento valley where gas heaters are the dominant standard for pools. Speak to most pool stores and installers in the region and they’ll tell you to go gas. My pool is an AGP 12x24, 54” just shy of 9K gallons. Folks tell you about humidity and ambient air affecting the efficiency, and Sacramento isn’t an ideal area. Yes, I agree that humidity isn’t the most ideal, but pool heat pumps do work and they’re still more efficient than gas units. Let me share my experience. Writing this review, it’s currently November 2020 with our “winter season approaching,” the electrician wired it and I fired it up. I have my pump pushing 40GPM (low flow), 2” plumbed to 1.5” for the intake. Starting water temp is 64 degrees; the average weather high is 75ish, low 42. I got mid 70 degrees of ambient air sustained for about 2 hours out of the day. I ran this for 3 days straight (72hrs) with a pool cover, and the current water temp is at 82 degrees (humidity – well, super low, 10%-35% max). Outflow from the LCD panel is currently showing 84 degrees in 66 degree ambient air temp. Sacramento temp will drop to about 39 degrees tonight for roughly 2 hours (I expect the efficiency to drop immensely and probably not do much), but during the last 3 days, when I checked in the morning, the temperature has been stable at 82. Running the pump/heater combo at night negated the potential 2-3 degree night loss. My AGP is not insulated. Funny… the owner called me to ask if I still wanted this after looking at my region and I told him to ship it! Our power company is SMUD; based on their winter rates ($.1235 p/KW blended) costs about $10 to run this heater for 24 hours (not factoring in solar panels). I spent $30, and 3 days to heat a 9K gallon pool in cold weather from 64 to 82 degrees; our temperature is continuing to drop for the cold fall season and we have a cold spell where top weather high is 64. I’ll continue to run my experiment and see how far I can push the water temp and have it sustain based on a shorter run time duration of 8 hours during the warmest part of the day. Heating is slow, but I expected that at 55K BTU. I have no doubt that once spring hits, this will heat-up the pool in no time. Based on my calculations, I can open the pool in early March and close it down towards mid-November. Heat pump inlet (i) / outlet(o). Day 1: AM 64i/66o, PM 70i/70o; Day 2: AM 70i, 72o; PM: 75i, 77o; Day 3: AM 77i, 79o, PM 82i, 84o. Average 6 degrees gain per day. Only time will tell how long this will last. Hopefully, this helps someone in making a decision on whether to make a purchase. Best of luck. BTW; shipping was fine; well boxed on a skid, no dents, everything was in good shape. I did get spooked on the morning day 2 when the heat pump went into defrost mode and I saw a big plume of water vapor in the air --- a few minutes later, it kicked back on. Update: 11/18/2020 – average H60* low is 39*; Pool peaked at 87* early November, but it is currently sitting at 82* with the solar cover on; pool heaters runs during sunlight hours 7A-5PM. And yes, I'm still swimming. ... show more

  • It definitely works but we'll see how the summer goes...
2 week update: It is now April 30th here in upstate NY, average high temp during the day is around 60 and low temperatures are getting down into the mid 30s. This thing has been doing an amazing job of keeping my pool warm. We had two nights this week that the low temperature at night was actually 33-34F and this was still able to get my pool back up into the 80s during the day (after a slight drop at night into the mid 70s). From what I've seen it looks like it is able to maintain a water temperature roughly 20-22 degrees above the ambient air temperature (but that is with my solar cover on the pool). This is really what I wanted to know before I bought it, so I hope that helps. This really only applies to people on the east coast as the air is much dryer out west. Also note that I have an 18' round above ground pool, which is roughly 8000 gallons. Original Review: Just got this installed on Friday and got it up and running. I live in upstate NY and it is still getting into the upper 30s and 40s at night. When I filled my pool Friday afternoon the water temp was 52F. It is now Saturday night, 9 PM, and the water temp is 64F. It was a nice day today and the high temp was about 65F, but there is no way the pool would have warmed up by 12 degrees in 24 hours on its own. NO WAY. So the heat pump is doing its job. I did the whole installation myself and it was relatively straight forward for me, but I've installed several heat pumps so I know what I am doing. I had to run a new 240V circuit down to my pool and I installed a new electrical junction box with mini breakers for the heat pump and filter pump. The startup of this heat pump is about as easy as it gets and it runs very quiet. A complaint I have with this is the ports they use for the plumbing connections. They are PVC compression ports (1.5"). Although the connections end up being fairly rigid and leak free once the compression fittings are tight, I would have definitely preferred a threaded MPT port as I think most would. The three pre-drilled holes and electrical cable glands they include are also kind of strange. I actually think it would be preferable if they didn't pre-drill any holes for the electrical and allow the installer to do whatever they need/want based on what they are installing. I ran 12/3 SOOW cord underground from my junction box and actually needed a larger gland than the ones included. Luckily I was able to get a larger one into the pre-drilled hole without modification, but barely. Had I needed a larger hole, it would have been a pain. I say either get rid of the pre-drilled holes or put different size knock-outs in the sheet metal. So far I am happy with it but I can't comment on longevity. I will definitely be updating this review sometime during the summer or early fall depending on how it runs throughout the summer. But I don't really expect any issues. ... show more

  • Works great, energy efficient, durable, great value
We are in the Dallas area. Our pool is on the shady side of the house so it only gets about 3 months of good sunshine in the summer. Other than that, our pool doesn't get enough sun to stay warm. Previously we had a Hayward HP2100 heat pump that died (bought it used). After much research and shopping around, we decided on the FibroPool FH-055. I had the 220 circuit installed by an electrician then I plumbed it in myself. I called the company a couple of times with questions and they were very responsive. After installation was complete, it heated our pool up pretty quick. We keep our pool between 82 and 84 degrees about 8 months out of the year now as opposed to 3 or 4 months of swim season without a heater. Our pool is 12x24 oval and is about 52" deep. About half is below ground and the rest above ground. For a good idea of the pool size for reference, the shed shown by the pool is 12x10 and we have a lot of trees (not good because of the leaves) that offer privacy but a lot of shade. If we use a pool blanket, we could probably squeeze another month or so into the swim season, but at some point, it's just no fun to swim when the ambient temperature is in the 60's. We cover the pool from about January until the last of the pollen and stuff falls from the trees around mid April. We have had the FibroPool installed now for about 2 1/2 years and I have zero complaints. We are very pleased with the unit. I highly recommend it. ... show more
