Solar-powered heating system warms Charleston couple's swimming season



CHARLESTON — Kelly and Walt Edwards enjoy inviting family and friends over to use their backyard pool, but without a heater they had been limited to only a few months of comfortable swimming per summer.

Last month the couple expanded their backyard swimming season by having a solar-powered heater installed adjacent to their pool southwest of Charleston. They hope to recoup their investment within two to three years by heating their pool without the need to purchase electricity or natural gas to power a heater.

The Heliocol solar-powered heater, installed by Green Power 4 Earth of Algonquin, uses the pool’s existing pump to direct the pool’s water through a series of valves to the solar collectors. The pool water enters the collectors at the bottom and rises to the top through individual tubes. As the water rises, it is heated by the sun’s radiant energy.

Kelly Edwards said the collector tubes have been arrayed on an approximately 14- by 24-foot deck that sits at an angle, with a wooden fence between the deck and the pool. She said this solar power heater increased the pool’s water temperature from 74 to 86 degrees within a couple of days.

“It’s a pretty big system but it sure does a good job. It warms the water up really well,” Kelly Edwards said, adding they like to keep the automatic temperature control set at 88 degrees.

Kelly Edwards said they originally purchased an electric heat pump for the pool, but this pump went bad. She said they researched other options before choosing the solar-powered heater because it would be economical in the long run and curtail their electricity usage.

The solar-powered heater should add about a month and a half of comfortable swimming to the beginning of the season and a month and a half to the end, Kelly Edwards estimated.

“We really enjoy it. We have a lot of kids out here all summer long and they are getting a lot of enjoyment out of it,” Kelly Edwards said, adding they have five children and three grandchildren.

Walt Edwards said, as an example, that there were some days in April when temperatures topped 80 degrees, but the chilly pool water had not warmed up enough yet to match the air temperature. He said this will not be a problem now with the solar-powered heater.

Allan Hottovy, who started his Green Power 4 Earth solar product installation company about a year ago, said the Edwards’ solar-powered heater is the first he has installed in the region. He said these types of pool heaters are common in the south of the United States but are not widely used yet in the north.

Hottovy estimated that heating a 1,000-square-foot pool with natural gas costs more than $2,000 per year. He said the solar-powered heaters, which are typically roof mounted, reduce the energy costs of maintaining a pool by 80 percent.

“This little thing will really help people live within their budget,” Hottovy said, adding the solar-powered pool heater is designed to last for 15 years or longer.

" We made our own version many years ago. It was made of a copper tubing
"grill"attached to the fence. A "garden hose" was placed on a fitting attached to one of the return jets which pumped the water through the copper tubing. Another portion of hose at the end of the tubing put the sun heated water back into the pool. Worked great. Since the pool pump was already on, it didn't take any nore electricity to operate it. The "man" always came up with great ideas that worked!

We also used a solar cover which looked like a giant piece of bubble wrap to help keep the water temperature up overnight. He even made the device to roll and unroll the cover saving us at least $200-$300 bucks. We only used our solar heater when the temperature was a little lower. When the air temp was in the upper 80's or 90's we didn't bother with it. The perfect temperature for the pool water on hot days was 86-88 degress. Anything warmer than that felt like a lukewarm bath. The reason for getting the pool is to cool off , not take a bath! :-) "

" Ron,

You ask a great question! Since the solar panels are made out of high quality SCH 40 PVC, it can be recycled for other uses. The rest of the structure is a wood deck and can be deposed of in a variety of ways.

Medic57,

Another good question. Yes, the solar array does cause the pump to work harder and use more electricity. The amount of extra electric used is dependent on the size of the solar panel array. The savings on your pool heating bill these systems give you more than offsets the slight increase in your electric bill.

If we all started using systems like these, they would lower our need for imported energy (currently around $450 Billion per year) and enable us to live with a lighter impact on the environment. As an added bonus, over the life span of your pool, you will save Tens of thousands of dollars off of your heating bill!

" Medic, it won't use any more electricity than the pump was already using. A 100gpm pump will always pump 100gpm (under normal circumstances). The only change would be the amount of water as the volume of the solar exchange tubes now have to be filled. "

" Thanks for sharing, Billie. Your message reminded me of something I saw several years ago while traveling through Canada and stopping at the Alexander Graham Bell home and labs.

Bell rigged up something similar on his roof top to create hot water for his shower. Another device he created was an air conditioning system that ran air ducts below ground surface and forced the cool underground air up into his home with a large fan. Bell's house was full of many similar devices, and is well worth the stop. Bell was no doubt a genius, but with a little ingenuity, all of us, as you shown can come up with ideas that work and are relatively cheap. "

" Amazing isn't it Harry what a little ingenuity can do? We had all kinds of things made by the big fella. He hated to throw anything away that might be useful. His workshop had all kinds of stuff he'd saved in it. I drew the line at storing that "junk" as I called it in the house though. LOL! I learned over the years that not only could he come up a workable solution to fix something, it always looked good too.

By the way, you know I'm not a liberal don't you Harry? We saved our money to have that pool put in. Finding ways to operate it economically just seems smart to me, not scrimping.

It was good therapy for him to swim due to the fact his mobility was diminished by the loss of his legs in Vietnam. It was a stress free way to exercise. He could lie on his back and float for hours if he chose to. He bobbed like a fishing cork in the water because his lower legs were gone and they didn't pull him down. Little kids( who had just met him) were amazed when they saw him plunge into the pool and saw him swimming like a pro!

Yeah I saw that one, I guess he figured out how to crack the name code thing. You know it's kind of funny that that name periodically pops ups after I acknowledged posting under it for a while to get him going. I don't have to do it now that I've figured out how to keep him cranked up. And as you've no doubt noticed that everyone who agrees with me or disagrees with him is automatically me now. Careful or you will accused of being me. lol. And hey I enjoy your "Toby" stories. I'm sure I'm not the only one who enjoyed hearing them. "

Since you're obviously trying to sell the conspiracy theory that I'm stealing names, Mr Potter- why I haven't I stolen your name yet Harry?

Can we expect you to start claiming that next? "

" PVC = Polyvinyl Chloride

Such an innocent sounding 3 letters and 2 words.



PVC - The Poison Plastic

PVC (polyvinyl chloride) plastic, commonly referred to as vinyl, is one of the most hazardous consumer products ever created. PVC is dangerous to human health and the environment throughout its entire life cycle, at the factory, in our homes, and in the trash. Our bodies are contaminated with poisonous chemicals released during the PVC lifecycle, such as mercury, dioxins, and phthalates, which may pose irreversible life-long health threats. When produced or burned, PVC plastic releases dioxins, a group of the most potent synthetic chemicals ever tested, which can cause cancer and harm the immune and reproductive systems.

New Car or Shower Curtain Smell? The Smell of PVC

PVC is useless without the addition of a plethora of toxic additives, which can make the PVC product itself harmful to consumers. These chemicals can evaporate or leach out of PVC, posing risks to children and consumers. New car smell? New shower curtain smell? Thats the smell of poisonous chemicals off-gassing from the PVC. One of the most common toxic additives is DEHP, a phthalate that is a suspected carcinogen and reproductive toxicant readily found in numerous PVC products. Children can be exposed to phthalates by chewing on vinyl toys. While it is still legal for US retailers to sell PVC childrens and baby toys containing dangerous phthalates, the European Parliament voted in July, 2005 to permanently ban the use of certain toxic phthalates in toys. One EPA study found that vinyl shower curtains can cause elevated levels of dangerous air toxins, which can persist for more than a month.

" So they took up 14x24 area of their yard, to erect this one purpose, one limited use "cost savings" system with a 15 year life span.

Wonder what the county tax mans opinion of this permanent structure using up 336 sq. feet?

Above ground or in ground pool, how big?

How much is this specific example, lots of projections, and estimates, but no mention of what this cost.

They make solar pumps, that will do decent gph and capable of 18 or so feet of lift. Could have built a shed, put this on the roof, and actually made use of 14x24 all year.

Array material, looks like hail and high wind, would do a number on it. especially if its essentially just black plastic over plumbing. I know its so many mil thick fancy black plastic. It looks like backyard pond liner.

If this is what someone wants, it and better can be a do it yourself project and actually be more functional, efficient, and green. Lots of solar ideas and plans are free through various sources. Could include a solar oven and grill, in the system, pretty easily, I would think.

Killing 336 sq feet of grass, for the sole purpose of swimming an extra month on each end of the swim season, isn't exactly green.

Now this thing is radiating excess heat down around the ground, out in the yard somewhere. All done so dragging the solar cover on and off can be avoided. Solar covers keep heat in at night, and impact evaporation loss, when the pool isn't being used.

They need to track how much more water and chemicals they use after installing this. Lots of waste, hiding behind the green energy collection, and the marketers aren't proud enough of it to give a ballpark price. Or show a picture of the pool and how it compares to the 1000 Sq ft example they provide.

How many folks have a 1000 sq ft pool. Thats around 31.63 x 31.63. Most pools are usually compared by cubic measurements or gallons of water to capacity, aren't they? Square feet, only indicates the footprint needed, to place it somewhere. Without the depth or total gallons of water, it is a poor and vague refference to base anything on.

Who heats their pools with natural gas in the first place?

Pools are already natural solar heat collectors, unless they get built in the shade, then they tend to be leaf and limb collectors. Their lining is colored light colors, to keep them from getting too hot. Most of the summer, I would want a geothermal pool cooler option.

They probably could have built a shed instead of the deck, in a way that sliding or removable panels, and ventilation, could have enclosed the pool, giving 365 days in their pool season. A green house or some other use of the space under the array deck, with collection of the water it will collect and trench the yard around it, if not dealt with. Lots more water, diverted to whatever is below this things slope. Deffinately not a design many people who value their yard or usable space in it, would rush out and buy, for who knows how much it even costs. An easier to use solar cover, system, could have done a lot of this, in alot less wase of space and resources.

It has an automatic temperature control they like to set at 88. Most of the summer, it usually would be on divert, with that system. Sure this week has been rare for July weather, but what is going on with the system, when heat index of 100+ and high humidity is going on for months around this thing, besides being a heat sinkover the fence from the pool? How much treated lumber went into this "green" investment? I suppose the lattice is pvc, to prevent rot from the heat and moisture collected.

This is the worst report I have seen from this usually more on the ball than others reporter. It really is more of a straight off the hand out of sales pitches by this company, than any community interest or informative value. "

" I recently watched a news report about a man in Buffalo NY on how he's using a new type of solar pool heater. It heats the pool and cools the home by recycling the solar energy inside the attic. There are no solar panels so you don't have to dedicate the entire yard or your roof top to accommodate a massive installation. "
