Do Solar Pool Covers Heat The Water

How Does A Solar Pool Cover Work

Do Solar Covers or Solar Blankets Actually Warm Your Pool Water???

A pool cover works in three ways:

  • It floats on the surface of the pool and allows the suns rays to enter the pool to heat up the water.
  • It acts as a giant blanket and insulates the pool which greatly reduces heat loss, particularly at night and during windy weather.
  • As no water is exposed to the air, evaporation is greatly reduced. The process of evaporation is one of the largest ways heat is lost from the pool.
  • Obviously using the sun to heat a pool is very eco-friendly and can save you money if you use a pool heater.

    Solar pool covers otherwise known as solar blankets are swimming pool covers that use the suns energy to keep swimming pools warm. But how effective are solar pool covers? Many pool owners are skeptical about the usefulness of covering their pools to retain heat or protect it. Read on for information on pool solar cover effectiveness.

    Ten years ago, the team at Elite Pool Covers set out to improve on all aspects of the run of the mill round bubble blankets and succeeded by developing the Elite Super Bubble Blanket that is proven to out-perform all solar types of round bubble blankets on the world market.

    There are a number of run of the mill round bubble type blankets on the market. These tend to keep the heat in your pool the same, as they all have similar small bubble size, same average insulating qualities, same lifespan and similar thicknesses.

    The Elite Super Bubble Solar Blanket is truly superior and is proven to outperform all other round bubble blankets according to independent scale tank tests and comparative guarded hot plate tests to Australian Standard AS4859-1.

    Solar Sun Rings For Inground And Above Ground Swimming Pools

    If a solar blanket seems like too much of a hassle to put on, take off, and store during the swimming season, you may prefer solar rings or squares. These can even be decorative because some of them have patterns and images such as palm trees printed on them, while others come in fun shapes such as flowers.

    Solar rings are sold individually for around $25 to $35 each, or in sets for around $140 to $160 or more, depending on how many rings come in the set. The number you need to cover your pools surface will depend on the sizes of both your pool and the rings.

    Solar Pool Cover Bubbles Up Or Down

    The 9 Best Solar Pool Covers of 2020

    Good question as it is not really obvious.

    However the answer to whether you have the bubbles up or down on solar cover is always bubbles down into the water.

    The bubbles side has a larger surface area than the flat side so heat is transferred into the water more efficiently than if the pool blanket was the other way around.

    The bubbles contain air and this is heated up by the sun and the heat is then transferred by the process of conduction. The flat side is the tough side whereas the bubble side is generally the least tough side. So having the bubbles facing down on the pools surface means they are protected from anything which may drop in the pool.

    The smooth side therefore faces upwards. The beauty of it being smooth is that it makes it easier to clean. You can run the hose over it before you remove it from the pool.

    One of the most valuable qualities of a solar pool cover is that it reduces evaporation, which in turn saves on energy and water costs and consumption.

    Water evaporates because of the elements. Evaporation is affected by climate, temperature and wind, and a solar cover provides a barrier of protection from those elements.

    Scientifically, heres the scoop: A pool naturally collects heat throughout the day, but is usually not enough to keep it heated consistently at various times of the day or year.

    It traps the heat in and protects the water from the elements. It also prevents heat loss caused by evaporation.

    A solar cover is a broad term for a group of substances placed or applied on the surface of pools to raise the temperature or hold warmth in the pool. These substances include solar blankets, solar rings, and liquid solar covers.

    A solar blanket, on the other hand, is a type of solar cover. It is made for warming pools, retaining warmth in pools, and reducing water evaporation from pools. Solar blankets are typically made from materials such as polypropylene, polyethylene, or vinyl. These materials come in various thicknesses , and they are sometimes UV-stabilized for durability. They may also come with air bubbles for higher heating efficiency.

    How Do You Get Water Off Of Your Pool Cover

    How To Heat Your POOL (3 Ways) | Swim University

    Some pool owners use a pump to remove excess water from a swimming pool cover. You can also help prevent this issue by choosing a swimming pool cover made of mesh: Dirt and debris wont be able to get through, but a tight weave will allow water to pass through. If you live in a part of the country where snow and ice are common, consider adding an inflatable air pillow underneath your pool cover. This creates a dome shape in the center of your pool, which prevents water from pooling and freezing in the middle of your pool cover.

You should keep the cover on as much as possible between swims.

    What Is The Best Color For A Pool Cover

    People often consider clear solar pool covers as the best type of pool covers. However, while clear solar covers offer the best heating, they may not always be the best in all situations.

    The best color for a pool cover may ultimately depend on your personal preferences and other factors unique to you. For one, if you prioritize rapid and efficient pool warming, then a clear solar pool cover will work best for you. If you also want more heat gain and a higher rise in temperature, you should get a clear solar cover.

    However, if you want some visual appeal, you may opt for a colored pool cover. Some of the solar pool cover colors available include blue, black, or grey. You may also get one with two colors or tones. Of such solar pool covers with two colors is blue-black solar covers and blue-silver solar covers.

    If you live in an area that does not get enough sunlight per day, you should prioritize heat retention. To this end, you should get solar pool covers with dark colors. It could be black, dark blue, or even dark grey. These types of solar covers will absorb and save some heat for your pool long after the sun is gone. This way, they make up for the short periods of light from the sun. However, you will need water circulation to distribute the heat within the pool.

    Although some colors are better in some situations, clear pool covers will always be valuable in most situations. This may be why they are typically considered the best.

    Properly storing your solar cover at the end of the outdoor pool season is essential if you want to prevent damage and replacement costs.

    • Lay the cover out on a flat area and hose it down.
    • Let it dry completely. You can use a leaf blower to speed up the drying process. Dont let it air dry for too long in the sun as it can burn/damage your grass.
    • Once dry, fold it up and place it into a container with a secure lid to prevent animals and debris from causing damage.
    • Follow all manufacturer instructions. In most cases, you just use water and no special cleaners are required.

    Liquid Solar Cover: The Future Is Now

    Is it really possible that you could pour something into your pool water that magically warms it up? Yup. Thats basically how liquid solar cover works. Except its not magic its more science!

    Liquid solar cover contains aliphatic alcohols, which form a monolayer film on the surface of the water, thereby requiring upwardly escaping water molecules to expend energy in forcing adjacent molecular chains sufficiently apart to pass between them

    In plain English? A one-molecule-thick layer of fatty alcohol sits on the surface of the water, inhibiting the waters ability to evaporate normally. Preventing evaporation prevents heat loss, and voilà! Your pool stays warmer than if you had no solar cover at all.

    Liquid solar cover ranges in price from about $10 to about $30 or more, depending on brand and whether you buy a single container or a pack of multiple containers.
