Does a covered pool lose water to evaporation?
If your covered pool loses water in the winter, you probably have a leak. An uncovered pool will lose water in the winter to evaporation in the same way it does during the summer. But the water loss is only about a quarter-inch on average during a 24-hour period when the pool is not in use.
How much water evaporates from a pool with a cover?
Water Loss Through Evaporation Evaporation is the number one cause of water loss. The rate of water evaporation varies depending upon location, temperature, humidity and wind, but it isn’t uncommon for an uncovered swimming pool to lose 5mm of water per day on average.
How much water evaporates from a heated pool?
If pool owners or maintenance workers are constantly filling up the pool, there may be a leak. On average, swimming pools lose about a quarter of an inch of water each day, yet variations in wind intensity, humidity and sunlight can drastically change water loss rates.
Do solar pool covers prevent evaporation?
75% of a swimming pool’s heat loss is due to evaporation. A solar cover minimizes heat loss from evaporation by acting as a barrier between swimming pool water and the air. Specifically, you can reduce your swimming pool heating costs by up to 70% by using a solar cover.
How much pool water evaporates in a week?
The average pool water evaporation rate is about a quarter of an inch of water per day or more than two inches in a week, which on a 33′ x 18′ swimming pool (an average pool size) is more than 2500 liters or approximately 600 gallons a week; this may vary depending on your climate and the factors listed above.
How much water does it take for a pool to evaporate?
How Quickly Does It Evaporate? For evaporation, anywhere between 2 millimeters to 2 inches per week is about what you should expect in terms of pool water loss. This largely depends on the conditions we mentioned above which are mostly governed by the climate you live in, but it also has a lot to do with the unique conditions of your swimming pool.
How much water does it take to evaporate a solar blanket?
On the flip side, if you live in Wyoming or Montana, have no water features and use a high grade solar blanket whenever the pool is not in use, it’s very likely you’ll be closer to losing 2mm per week, if not less. There are pool evaporation calculators you can use, and they work pretty well if you can feed them with accurate information.
How to calculate the energy required to evaporate water?
The evaporation rate of water from a swimming pool is fairly easy to calculate; given you have access to a psychometric chart or a water vapor tables. W= (A (69.4+30.8 (V)) / Y ) (Pw-Pa) W = lb / hr of evaporation. A = surface area of the swimming pool. V = mean wind velocity (mph).
What can I use to block evaporation in my Pool?
Use a solar pool cover (or blanket). They’re like regular pool covers, but they also absorb and transfer heat into your pool water. In other words, not only do they block evaporation, but they provide additional heat to your water. They also come in the form of smaller rings and even bottles of liquid.
How much water does a solar cover heat up a pool?
These solar-powered covers heat up your pool by preventing water from evaporating. If it’s not covered, it can lose up to two inches of water a week. While it may not seem like much water, it can add up to at least 10,000 gallons of water each year.

What can I do to slow down pool evaporation?
1 Using a Solar Cover. We highly recommend that you put a solar cover over your pool when it is not in use because it can slow down evaporation by 95 2 Getting a Liquid Solar Blanket. 3 Turn Water Features Off When Not in Use. 4 Install Windbreaks. 5 Lower Water Temperatures.
