Features

  • CLEAN AND GREEN: The FH135 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 7,500 gallons and above ground pools up to 18 foot round or 12 by 24 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

  • Expensive, but worth it!
We were first time Intex above-ground pool owners in Iowa, and knew we weren't going to enjoy our pool if the water was freezing. This FibroPool heat pump was EXPENSIVE, so it was a gamble that it would actually keep our 8400 gallon pool heated, but it was worth it! We found we liked it set at 86 degrees, and added one of those blue bubble-wrap looking solar covers to help keep the heat in. Most days the heat pump didn't even run as the water was still at the right temp. It maybe only took a couple of days to get our initial 70 degree tap water warmed up. The heat pump is VERY quiet, which was a plus. We also specifically bought this model of heat pump because it used a regular 110v outlet. We did end up having our electrician come out and put in a dedicated outlet for both the heat pump and sand filter so they didn't trip (our fuse was too small.) We did have a little bit of trouble understanding that the included threaded adapters for the inlet and outlet were just that - adapters, so be sure you have the proper threaded hoses to go back to your pool (again, rookie mistake on our part.) We ended up needing a longer threaded hose for the outlet back into the pool just due to the distance from our outlet as the cord on the heat pump isn't that long and we didn't want to run it on an extension cord. Overall, we are extremely happy we took the chance on this heat pump. We were able to enjoy our pool even when the nights dipped down cool. Nobody likes getting into a freezing cold pool! ... show more

  • Happily ever after
Awesome! My son-inlaw and I are always skeptical about products, but our above ground pool was not getting used that often because the water was so cold, so we gave this heat pump a try. Right from the moment it arrived, everything looked good. The product was nicely packaged, the design on the outside looked clean and sleek and all the advertized parts were supplied. I actually didn't think we could hook it up easily, I suspected hose fitting issues, but we had it hooked up and plugged in in under an hour, with no leaks! Within 48 hours the pool temp is at a very pleasant 88 and we can hardly hear the pump running even when we're in the pool. ... show more

  • Works Well & A Fun Project
With days in the 70s and nights in the high 40s, this heater took about a week with the solar cover on the pool to move the temp up from 66F to 88F degrees. Now that it has reached the set temp, the heater does not run at all (which is good) until the water temp drops a few degrees. Overall I am happy with the product. It is easy to use and seems well made. I can't speak for its durability or weather resistance just yet but I will add to this review if time or weather creates any negative effect. I decided to install this heater myself for my 6800 gallon in-ground fiberglass pool and of course, I had lots of questions about how to build the PVC bypass system. Brennon, the customer service tech, answered all my emails quickly and clearly, and although I don't have a ton of plumbing experience, I took my time with it and designed/built the system in a few days. It turned out to be a fun little project and the result is an efficient and leak-free system that seems to have very little, if any effect on the overall efficiency of the pump and filter. Designed with as few elbows as possible, I used an "H" design bypass with 3-way valves so that in the warm seasons I can set it so the water bypasses the heater completely, preventing corrosion in the heater. After the bypass, I used flexible spa hose to connect to filter and chlorinator. No problems yet. I would definitely recommend this product but with a warning: if you are not handy with plumbing, hire a plumber to install. If you own an above-ground pool you can disregard this as they don't require a bypass system and require only simple flexible hoses and clamps. ... show more

  • Exceeded my expectations
I had this unit installed to heat my 18-foot round Intex pool about one month ago, and it has exceeded my expectations. The water was initially a frigid 61 degrees when I opened my pool, and within 48 hours the temperature climbed to 85 degrees. It is now at 90 degrees, and feels just heavenly. I did have a professional pool service company do the installation. This heater has been a game changer, taking my pool to a whole new level of comfort and relaxation. I am also pleasantly surprised how energy efficient it is; my electric bill has increased by only around $40/month, and I run this thing 24/7! ... show more

  • Works as advertised and is well constructed.
This unit heated our pool up from 59 degrees to 81 degrees in about a week. That may sound slow, but our outside temps at night were in the 50s. So far I have been impressed with its ability to keep the pool warm given our recent cold snap. I've only had the unit for a few weeks; so I'll update if things if my impressions change. It seems well constructed and the instructions were fairly easy to follow. It is kind of pricey, but if it allows us to use our pool more often and longer into the fall, it will be worth it. ... show more
