Heating an Above Ground Pool
Hello,
We have a 25' above ground pool (48" deep), and we are looking for ways of heating the pool now that it's starting to get cooler outside. We live in Texas, and though our winters aren't bad, when the temp stays below 85'F for most of the day and 50's at night, the pool gets quite chilly. I'm looking at some options for heating the pool so we can use it throughout the winter, or at least a few more months into the fall now that the 90-100'F temps are gone. Does anyone have any experience with the solar heaters? I know even when the temp stays in the 80s for most of the day the car is still VERY warm, so I'd assume this is enough to heat the pool rather well with a solar heater. We're looking at one similar to this: http://www.intheswim.com/Pool-Heater...-Ground-Pools/ We just put the pool in earlier this summer, so paying another $800 or more for a powered heater isn't really possible -- but if we can get good results from a solar heater, we'd like to go that route. We havep lenty of space for it behind the pool. Thanks for any advise or suggestions -- Alex |

Heating an Above Ground Pool
A friend of mine bought a used pool heater on eBay for cheap, like $125, and it was local so he picked it up. Those things are a few hundred bucks even for a small one. Anyway, they're still using it after 5 or 6 years. When pool heaters are used a lot, they could develop problems that could cost more than $100 to fix, but if you can find a newer one for a great price, go for it. Sometimes people move and have to take apart a pool, and can't take it with them, so they sell the heater, and sometimes cheap too. Narrow down your eBay search to within 100 miles of you or whatever. Some people think heaters are only for larger pools and in-ground pools, but if I had a pool regardless of the size I would have a heater. There's a BIG difference between 75 degrees and 80 degrees. There's a safety issue too, when your kids lips turn purple and they seem tired after being in a cold pool, that is a BAD thing. The neighbors at our previous house put in a huge pool the year before we moved, and rarely used it because the water was always ice cold, even when it was 100 degrees outside. One of the reasons we moved was because we knew that it was only a matter of time before they found out about pool heaters, and then they would be in the damn pool all day and all night and the noise would never stop. (They weren't nice people.) Here are a couple other ideas I have seen: -- My neighbors have a black solar flat panel thing that wraps around one side of their pool. It's connected to the filter, so the water that is sent out of the filter goes through the black thing and gets warmed before being dumped into the pool. -- I've also seen someone put an array of copper pipes on their garage roof, and the filter water would run through the piping and warm the water before going into the pool. Roofs get pretty hot in the summer, so I would imagine if there was enough piping and the water ran slow enough, this could actually make the pool hot. Now, the above two ideas may not help you at night, but if you're not going to swim during the day you can heat up the pool enough so that it would be warm for you at night. Good luck. ------------------- Alex wrote: Hello, We have a 25' above ground pool (48" deep), and we are looking for ways of heating the pool now that it's starting to get cooler outside.

Just a cheap plastic one is adequate. It also keeps the dirt out and the chlorine contained. Only problem I had was the water getting too warm. If you have low humidity the temperature drops fast if there is no sun. When I lived in the San Fernando Valley a neighbor put up an array of black plastic pipe on the roof of his patio and pumped his filter water through it. Only problem there was the two foot waves during the quakes:-). Another problem I had was the liner rotting from the sun. That is the area just above the water. When I replaced the liner I cut a piece fro the old one and had sort of a skirt all around the pool covering the new liner and keeping the sun off it. |

I do all my own repairs. On my small $800 heater, I'm averaging about $100 a year in repairs. So far I've replaced the heater manifold, the pressure switch, the control circuit board and the hose fittings. I expect next year to have to replace the blower, it's seriously rusted. If you don't do the work yourself, expect to pay at least double. |

Positioned in the yard with ample sunlight all that was needed was to connect a pump. If recollection is correct the biggest problem was the water became too hot! |

We just moved in a few weeks ago, and the previous owners went ahead and closed the pool for us, so I can't say if it actually works. There is a black hose coming and going from the machinery, and the length of the hose was coiled on a low wooden platform/table-like thing, the surface of which has some kind of reflective foil on it, and the hose was coiled up on that. I'm glad to here someone mention this here, as it seemed a little duct-tapeish to me. I think there's a solar cover in the shed as well. -Karen- |

Heating an Above Ground Pool
To follow up on the OP's observation on the hot car:
Buy an old junker for $50 - preferably one with vinyl seats (black, of course!) Park it where the sun shines all day, and close to the pool Buy 8 or 10 50 foot garden hoses and connect them end-to-end Wrap them around the steering wheel, door handles, across the dash and seats Connect to an inexpensive pump and let it curculate the water from the pool Wha-La: heated water for you pool!

In Austin, 940 Btu/ft^2 of sun falls on the ground on an average 48.8 F January day with a 58.8 daily max temp. An R1 cover with 80% solar transmission would make 0.8x940 = 24h(T-48.8)1ft^2/R1, for a pool temp T = 81 F. An R2 cover with 3 layers of plastic film and 70% solar transmission would make T = 104. An 84 F pool with a 491 ft^2 R1 cover needs about 24h(84-48.8)491/R1 = 415K Btu/day. If 1 ft^2 of 4/12 (18.4 degree) south roof collects 940cos(18.4) = 892 Btu/day of overhead sun + 1200sin(18.4) = 379 Btu of south sun, totaling 1271, and 80% enters an 84 F collector when it's 53.8 outdoors for 6 hours and 0.8x1271-6h(84-53.8)1ft^2/R1 = 836 Btu/day, you might heat the shaded pool with 415K/836 = 496 ft^2 of roof, eg buy a $129 No. 412700 27' round clear vs blue pool cover from http://www.solarcovers.com (800) 433-4701 and put their $99 411632 16'x32' cover on a roof over wires to keep it from gluing itself to the roof when there's no water trickling over the shingles beneath it. With RC = R1x62.33x4' = 249 hours, the pool would cool from 84 F to 48.8+(84-48.8)e^-(5x24/249) = 71 F over 5 cloudy days. In a cloudier climate, we might heat a pool with a cover inflated with air during the day and soap bubble foam at night that can sink to the bottom for swimming. In Phila, 620 Btu/ft^2 falls on the ground on an an average 30 F January day. If 0.8x620 = 6h(84-30)1ft^2/R1 + 18h(84-30)1ft^2/Rv Btu/day, the cover needs US Rv = 5.7 at night, about 2" of foam.

ups.com... We have a 25' above ground pool (48" deep), and we are looking for ways of heating the pool now that it's starting to get cooler outside. Three basic methods: 1 Conservation = use of a solar blanket (bubble blanket) to delay loss of heat on cool nights. 2 Active heating, burning electricity or fuel. 3 Passive solar = adding to the pump circuit a long length of black hose exposed to the sun. During recirculation, this travel through sunshine increases water temperatures 2 to 5 degrees Celsius even in Canada. Special multi-channel hose is sold specially for this purpose. -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |
