Pool Heating

yes

A darker pool liner will absorb more energy from the sun and release it into the water, making it slightly warmer. Lighter colors won't have that effect. The warming isn't really significant enough though to justify getting an ugly liner because it's dark, using a solar cover will be more effective. Keeping the solar cover on overnight will help the water retain heat as well.

read the pool heaters manual.

24 foot round pool would be 24 feet across from the middle of the pool basically measure the diameter of the pool.

As far as a barrier is concerned you will need a fence that meets the same requirements as a pool fence. The barrier will need to be at least 48 inches tall. If it is a picket style fence with spacing between the vertical members, no spacing can be over 4 inches (I recommend no greater than 1-3/4 inches). The horizontal members should be greater than 45 inches apart and the bottom of the fence should be no more than 2 inches up off the ground level (or deck surface). The gate needs to open away from the jacuzzi. You must use self closing hinges and self latching hardware. The release mechanism for the latch must be installed above 54 inches. This makes the Magna Latch and Tru Close Hinge the perfect fit. This is not a comprehensive list of requirements and certainly different areas of the US may have varying pool code requirements. For this reason check with your local department of inspections or other governing body.

The bubbles need to go in the water, facing the bottom of the pool.

No because the waterbed heater is not meant to get wet and can cause an electrical shock;

also it could get hot enough to melt the vinyl of the pool liner.

The waterbed heater most likely has a warning on it to not get it wet.

If you want an electric heater for your pool you will need to buy one.

Solar covers work well to prevent heat loss through evaporation.

A black bottom pool will be slightly easier to heat than a white bottom pool, but the difference will be very, very small.

Yes, some very small amount of extra energy will be absorbed by the black color and absorbed into the water that would otherwise be reflected by the white color pool, but this small amount of heat is dwarfed by the large amounts of heat that are lost or absorbed by the water due to air temperature, wind speed, evaporation, cover, heating method, etc.

Most people choose their pool color based on design and/or looks and then get a good pool solar cover to help keep it warm (regardless of the color).

Highly unlikely, unless you don't cut it properly and leave part of it overlapping the edge of the pool. As long as it's floating on the water, it would take a heck of a storm to blow it off.

Get a role of valcro strips and cut them into 6" strips. Attach them to the reel and the cover at about every 3 feet. Then attach the strips together and you will be able to reel the cover onto the reel and it will stay tight.

It'll start immediately, but to due to the large volume of water it will be awhile before you sense it.

A. they do make blue/black covers that have a blue top and black bottom so the suns rays go through the blue layer and absorb in the black layer causing the heat to go from the black layer into the water B. if it was solid black it would absorb the rays and heat up the top of the cover and wouldn't transfer into the water

Yes you can. However I have not dealt with freezing winters, so this may be a different situation. if the water freezes over there is a distinct chance that your pool will crack as a result of the expansion of thee ice. I have heard that by placing a couple of rows of plastic containers floating on the top of the water this problem can be alleviated.

I have had several pool covers over the years, blue, blue and black, clear, clear with diamond shaped bubbles. Last year I purchase a "Gold Series" solar cover. It is blue on the top with a reflective good metallic layer that faces down. This cover is by far the best cover I have ever owned. It's high quality but more importantly I have 5-7 more degrees in water temperature then I have ever had. In July I had to take it off the water was so warm. Very pleased.

There should be valves to redirect the water to and from the spa.

Corrosion can present a problem below 7.0. As the pH falls below 7.2, chlorine become increasingly more aggressive and irritating. Depending upon the type of pool vinyl lined or masonry - corrosive low pH conditions can cause surface etching, liner wrinkling and equipment damage. A pH of 7.2-7.6, helps assure bather comfort, allows effective sanitizing and helps avoid corrosion.

Lay your solar cover, bubble side down on top of the pool

Just want to add, we bought a solar cover for our above ground Intex pool. The cover completely covers the pool and keeps the pool water very warm (which is the purpose). However, you need to double your chlorine to keep from getting algae. It's almost like having a spa. When I lift the solar cover, there is condensation on the cover and steam coming out. So you need to really watch your chlorine levels.

:

You may also want to try using a liquid solar cover. They are really easy and relatively inexpensive...best of all, you don't have to put them on and pull them off all the time. Check out www.liquidpoolcovers.com

Yes they do. Plus they are safer most are capable of generating more heat that a solar cover. The effect is that Solar Sun Rings with 70% to 80% coverage outperform bubble pack covers with 100% coverage.

It depends on the size of your pool, the number of panels, your location and the desired temperature gain.

Assuming my panels are equal to the sf of the surface area of my pool in (for example) North Carolina I can expect to see about a 1 degree rise per hour using a blanket during the sun, so when you first turn on a solar system it can take 3-5 days to fully heat your system but once it reaches that point it keeps it warm from then on.

All Solar Pool Covers are placed on your swimming pool with the bubble side down, or facing the water. This allows an air pocket to form under the cover to trap heat & provide the maximum insulation value the cover is designed for. -Charlie Goss President DPD Pools / PoolDeals.com

To get rid of water mold in a Baquacil pool, the best thing to do is add Water Clarifier to the skimmer with the filter running, add Flocculant as a filter aide, let filter 8-12 hrs, vaccum to waste, and then chemically clean the filter. It is very important to chemically clean the filter because while you are backwashing the water mold will cling to the filter and if it is not chemically clean it will filter back into the pool and start to form again. I have an email from some one with this problem it may be helpful to you

We live in New Mexico where our pool season runs approximately seven months. It gets hot starting in June and stays with daytime highs in the 90's until mid-September. We use Baquacil (biguanide) or basically a peroxide based product in our pool. A lot of people are abandoning this system due to the mold/algae problems that seem to eventually develop with it. I don't know what they're pool maintenance routine is, but I do not believe any system will give you a pour and ignore environment. One still has to do routine maintenance to have a sparkling pool. We were close to converting to chlorine due to the problems we were having, but the Dragonfly has helped to bring the problem to a virtual halt. It has also greatly minimized the need for brushing the sides as it really does collect a lot of the debris that once accumulated on the bottom of the pool. We use a sand filter which runs 12 hours a day.

I don't know where water mold comes from. I've been told it's in the water itself, I've been told it's in the air. All I know is it comes from somewhere and there was nothing more disgusting than these large floating island masses of slimy strings in the pool. You can chemically treat the water with everything in the book and they do not go away. They live on the surface and unless you can strain the surface of the water through a sock, the problem persists. They also foster all the other nasties that like to invade the water and make it unsightly. If you cure one, it appears you cure them all. Your Dragonfly is my remedy. I thank you.

You more than have my permission to use any praise that I have bestowed upon your invention.

I spent a lot of money on chemicals (roughly doubled what should have been spent the past two years) and did not have a positive outcome with any of them. Last year in a two week period we poured 14 gallons of oxidizer (shock) in the pool to combat the water mold. With all this product in the pool, the shock still would not register on the water test, the "little things" were just gobbling it up! You could not stand close to the pool because of the chemical odor and it did not help at all. We ended up just closing it in July in disgust and not wanting to literally pour more money down the drain. This year, our pool is still clean and sparkling and doesn't have a ton chemicals floating around in addition to not looking good or smelling good. The Dragonfly works, plain and simple.

And, we are using less chemicals at this time. Not a big difference yet but a difference. We use less sanitizer and algaecide. This may not seem like much, but I think it's miraculous.

It depends on the type of system, smaller heaters like an El Nino or Ez heat you may see only 10 degrees, with a Bigger name brand pool heater like a Fafco or Vortex system you will see up to 20 Degrees above ambient air temperature. So in places like Florida you can use them to basically swim all year round.

Black - Blue - Clear. In that order.

But the differences between black and the other types are not very great, so many people make their choice based on other factors: - appearance (some people don't like the look of a black pool cover) - cost (some retailers charge different prices) - availability (some retailers only stock certain colors).

I would say that Blue is probably the most common.

Hope this helps ...

The greatest heat loss in any pool is from water evaporation. Any pool cover will reduce evaporation. Generally, the thicker, the better. Most high end pool covers are extruded instead of laminated. The extruded cover will last about two times longer than any laminated cover. As far as the sunlight is concerned, heat can be retained from the sun similar to the greenhouse effect. The more sunlight that passes through the cover, more heat is retained in the water. Example, if you were to paint the bottom of your pool black, more sunlight would pass through the clear cover to be absorbed into the black bottom of your pool, transfering that energy into heat. Please realize that I am getting quite technical here but I am trying to explain the physics involved. There are not very many pools with black bottoms!

Bottom line is this: The greenhouse effect to retain heat is very minimal. Therefore a clear cover may have a very small advantage...but....chloring is also broken down by sunlight. A clear cover will allow more sunlight to enter the pool, therefore shortening the cholorine life. Just my thoughts. Hope this will help. I have decided to try an extruded, clear cover this time.
