Description
How warm will my pool get? With moderate to high humidity levels, you can expect to keep your pool 15 degrees warmer than the outside air, up to a target water temperature of 82 degrees Fahrenheit. How cold can it be outside? The minimum suggested operating temperature is 50 degrees Fahrenheit. Colder temperatures will result in worse performance and efficiency. Can I use it with my saltwater pool? Yes, all FibroPool heat pumps are compatible with both fresh and saltwater pools. Just ensure the unit is installed upstream of your chlorinator or salt cell with a check valve to prevent backflow. What size pump do I need? This unit requires at least 25 gallons per minute of water flow to trigger its flow switch. For most pool installations a 0.3HP pump or greater is sufficient. We started as a small retail store on the Mississippi Gulf Coast in 2002 with the mission of providing professional-grade pool equipment to the everyday homeowner. Twenty years later, we're still headquartered just a few miles from that original location. We take pride in our commitment to excellence. Our company culture is based on honesty, transparency, and professionalism, and we strive to build long-term relationships with pool owners by providing exceptional service and quality products.

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.

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.

Shipped fast, easy to set up. Within 3 days my pool was at 85. I'm in the Pacific NW so it's cold often and this does the trick. I have a 12x24x52" Intex Ultra Frame with a Saltwater sandfilter system. The hook up hoses took a bit to figure out what I needed. I'm super happy with this purchase

I’m not overly thrilled with this unit. It was touted as a great heater but I’m not impressed. I liked that it was supposed to be quiet, efficient and heats up fast as well as stands up to salt water. My experience is that it is loud. The fan is making a noise and will not stop. Like it’s out of balance. Moreover, the control is absolutely ridiculous to operate. Good luck remembering the steps to turn on. There are all kinds of pre set settings and turning on and dialing in the temperature is so frustrating. Then when you do get it to work and you think it’s heating up, it takes days to warm up. I’m in FL 10k gallon pool and this thing takes over 3 days to go up 10 degrees. That’s ridiculous. I’m also trying to get in touch with someone at FibroPool and no one responds! I’d like to get a wifi or remote adapter to control this unit since it takes so long to heat up but cannot get any response from them. The price point is good and reviews were what led me to this one but I’d rather have gone with a better unit at this point. Not thrilled with this. Lastly, there is zero customer service. You cannot call anywhere as numbers are wrong and no one responds to emails. You have to message via Amazon only and they tell them to contact you. Very frustrating to deal with them when they do finally contact you.

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.

The FibroPool FH055 can be used to heat water for a lot of things beside a pool. It works great and its not much louder than a refrigerator. If installing yourself, the hardest part is the concrete slab. Remember to drive in the grounding rod. The plumbing and electrical are pretty straight forward. Make sure the 1-1/2 inch plumbing connections are real tight. Mine came off the first time I supplied water pressure. The three supplied electrical connector ports are not very useful and the knock outs are larger than 1/2 inch but smaller than 3/4. I used 3/4 liquid tight connections and had to enlarge one of the holes slightly. There's a kit available to allow you to move the LCD display, user interface inside the building. You'll need to head to the hardware store to get the correct rubber grommets to fit tightly around the wire instead of the ones provided. You'll also need at least one 3-position small gauge screw terminal block for the data wire, as you won't want to cut the connectors off the originals, and the kit wire is probably too long, as it was in my case. The manual says you can program run times, but I wasn't able to figure out how, and the manufacture hasn't yet gotten back to me on that. Perhaps there is a firmware upgrade. The water pump can be controlled by the heat pump, but to do this you need a 240vac relay, even if your water pump is 120vac. You will also need to change the default setting parameter 9 from 0 to 1. Overall I'm very happy with my FibroPool FH055 and it is doing the job a lot better than the resistive electric heat I was using before, and there's no electrodes to build up calcium deposits on.

I have a very small pool and installed this unit in California's January sunny clear skies 70+ degrees month, and while it works to maintain the water at levels a few degrees above natural water temp, it doesn't "heat" the pool. Unless your pool is the size of a jacuzzi, maybe it'll work then. I was going to return, but the shipping will cost me $300; i'm waiting to connect this unit to my jacuzzi and see if it can heat that up. I highly recommend to anyone searching for this type of product to shop for heat pumps in the 130,000 BTU+ range. I replaced this with the Jandy 3000 and it's working, though struggling through cold nights, it's at least raising the temperature slowly but surely. This FibroPool product is mediocre at best, i don't understand the 5star reviews, unless you're only trying to heat the pool in summer/spring months maybe. I'm using it to keep my pool at 80+ degrees year round, so this product wasn't for me.

This heater works great if your pool is less than 10K. I would also use a solar cover. My pool is an 8.7K 12x24 pool. I have used this heater for one month. It works well, but it shines when temperatures go above 75 degrees and higher. I'm in central NC, and my pool hit 90 degrees in April with this heater and a solar cover. We had temps in the low 80s for parts of April. Tech support is good, but you will have to wait for emails. They usually email within 24 hours. Make sure you plumb it so it has a diverter. You might have to slow the water flow down for it to heat. Try to get the diverter to push the temp increase about 5 degrees and then leave it alone UPDATE It's not June we have had one of the coldest Junes on record. I have updated this buy to a 5-star, due to the cost of running this in my area to about 18-20 cents an hour. The average overall temp has been just below 70. Right now as Im typing this we have had a week of 60s and low 70s as highs. Yesterday the rain ended after 5 days of it. The temp of my pool had dropped to 79 with the solar cover on. I started my heater yesterday it went from 79 to 86 on a 79-degree high day. Today it went from 86 to 90. Today is an 82-degree day. We are swimming again! Almost all pools in the area that are un-heated are sitting in the upper 70s in late June :( Mine is warm 90. Advice get a solar cover with a roller it's that important so you keep that heat in the pool at night and it boosts the heating during the day.
