One of the main advantages of a dark bottom pool compared to light colored pools is that the darker color will help absorb more of the the sun's heat to increase the water temperature accordingly.
They are very cheap but they also have to be replaced more often and don't have the best longevity. They are sensitive to chlorine though, so they may lighten in color faster than planned if you clean your pool too often.
When ultraviolet rays (heat) are absorbed by the pool, the water temperature naturally increases by 3-5 degrees in direct sunlight. So, if you live in a cooler climate, a darker pool surface can almost act as a small-scale pool heater.
Now finally, we find that the temperature difference between a black pool and a white pool is: Δ T m a x = 220 k W h 4000 J k g ∘ C ∗ 36000 k g ≈ 5.5 ∘ C ΔTmax=220kWh4000Jkg∘C∗36000kg≈5.5∘C So, roughly 5.5 degrees of difference at most, which is not bad if you ask me.
Dark colours absorb light and heat, which will help warm up your pool water. Dark liners also hide dirt, stains, and debris. So if you have any hard-to-clean stains, you won't have to worry about seeing them every time you go swimming.
Dark blue is easily the most popular color of vinyl liner, probably because it's the most water-like of them all. It doesn't have the specific mystique that black offers, but it does offer some of the same masking abilities when it comes to dirt, debris, stains, and scratches.
Homeowners with dark bottom pools have also said that their pool seems to stay warm a little bit longer since the darker color absorbs more sunlight (and retains more heat).
Pool water temperatures typically run between 78 and 82 degrees. Any cooler than 78 and you may come out of the pool shivering. Any warmer than 82 and you may feel like you're taking a bath. So you could say that 78 degrees is the minimum swimming pool temperature and anything over 82 degrees could be too warm.
According to The United States Water Fitness Association, water temperatures for younger children and the elderly will generally need warmer temperatures ranging from 84 to 94 degrees Fahrenheit, while a comfortable pool temperature for adults is 85 to 89 degrees.
Water temperatures are slow to heat up, and just as slow to cool down. Water is very "stubborn" to change temperature. It takes 4 times the energy to heat up water than to heat air. Water also "feels" colder because water is a more efficent medium than air to cool our body down.
Color. “A UV-protected, translucent blue color offers a better balance between heat retention and pool chemical protection,” Dobrica says, adding that a clear cover will warm the pool water the most, but it will also allow more UV rays, which can make chlorine less effective as a disinfectant.
The colour of a pool has a significant impact on its temperature. A darker pool attracts and absorbs heat, while a lighter pool reflects it. A dark pool can be up to 2-3 degrees warmer than a lighter pool.
This is a very controversial topic in the industry with answers on both sides. Some swear that with a darker liner their pool is 5-10 degrees warmer. Others claim that the darker color has no impact on their temperature. The fact is that technically, darker colors help absorb the sun's heat.
Although it sounds shady, it isn't. in fact, dark pools are legal and fully regulated by the Securities and Exchange Commission. Dark pools allow traders to make block trades without having to publicize the buy/sell price or the number of shares traded to the public. This means trades are done anonymously.
Vinyl pool liners typically come with warranties of 20-30 years, which can be misleading, because this is not the typical lifespan of an average pool liner. In most cases, you can expect inground pool liners to last between 6-12 years, and above ground pool liners to last 6-10 years.
Not only does this color signify cleanliness, blue and white are also believed to show imperfections the best in a swimming pool. Therefore, if your pool is dirty you will be able to see it more clearly, and address the area that needs cleaning.
Pool water temperatures typically range from 78ºF to 82ºF. The American Red Cross recommends a temperature of 78ºF for competitive swimming. This coincides with good fuel savings. However, this may be too cool for young children and the elderly, who may require a temperature of 80ºF or higher.
Set your pool heater's thermostat to a temperature between 78°F and 82°F (26°C and 28°C) to keep the majority of swimmers comfortable. Maybe a little cooler if you're in an area with very hot summers, or a little warmer if you live in a milder climate.
Generally speaking, pools lose approximately 1/4” of water per day on average, though this can vary due to factors like wind, temperature, humidity and of course, the pool's total surface area.
So, what IS the perfect temperature? Typically, the perfect pool water temperature runs between 78-82 degrees in the spring and fall months. However during the winter month's it seems to drop to an ideal temperature to 76-78 degrees.
How Long To Heat a Pool? An average sized pool (rectangular 16×36) will take 6 hours to heat 10 degrees with a standard heater (300k BTU). The volume of water to heat, how many degrees it needs to increase and the size of your heater all play major factors in the time needed to heat your pool.
Covering won't lower the temperature of your pool drastically, but it will prevent the water from getting warmer. If the water is at the temperature you want, make sure to keep it that way by covering it up tightly whenever you're not using it, especially during the day.
A pool that is uncovered can lose up to 5° F overnight; a good cover can cut that loss by half.
