How Fast Does a Solar Cover Heat a Pool

0

Heating pool water becomes the first thought of pool owners when wintertime hits up. Most people like doing things affordably, right? Heating pools using pool heaters can be quite expensive, so pool owners will look for best alternatives to do this. Maintaining your pool water warm is vital, especially in the colder months and you feel like swimming a little bit. Solar pool covers have for long been identified as best alternatives for this exercise. But then, do they heat the pool? If yes, how fast do they heat a pool? The answers here will depend on the type of pool that will be covered, how warm or cold is the weather around, the strength of the wind in the area you live among many factors. Even though the solar covers heat the pool, this is not an overnight thing, and you’ll need to cover up the poo well to get results. Let’s first learn about the types of solar covers.

The Types of Solar Pool Covers.

Solar sun rings

These are lightweight and easy to use solar covers in the market. They work effectively to all types of pools, the inground, above the ground and intext pools. The covers are made up of two layers of UV resistant vinyl to help in reducing water evaporation also retaining already absorbed heat from the sun. The covers are designed with solar rings connected through magnets to each other to enable them to stay in place while in use.

Liquid solar covers

These are modern solar pool covers designed entirely invisible. The liquid solar pool covers are the most convenient options when compared to existing market types. The best part of this pool cover is that you can swim while they are working. Besides, the solar cover is capable of reducing water evaporation up to 40%. However, the liquid covers are used at specified doses. The dose depends on the size of the pool; bigger pools will take up big dosages and vice versa. Lastly, these covers are convenient for all types of pools; they are the modern option of working efficiently to keep your water warm for an extended period.

Solar blankets

This is the third type of solar pool cover; they are also referred to as the bubble solar covers. They have been designed looking like a sheet of bubble wrap. The sheets trap UV rays from the sun that later keeps the water in the pool warm. Additionally, the solar blankets tend to maintain moisture which in turn reduces evaporation.

When you’re in the market purchasing a pool cover, you should consider getting a slightly bigger option. You will trim it at home to get it fit perfectly to your pool. This way, you’ll cover up the pool well to effectively retain heat.

Besides this, solar sun rings and solar blankets are made of plastic. They are prone to deterioration, especially when they get into contact with chemicals and other environmental agents like wind and rain. So, depending on the climate of the area you live, it’s recommended to replace them after two or three years.

The sun that strikes on the surface of the pool usually gets stored as heat. Water is also transparent; sunlight can pass through it freely. As the cover absorbs sunlight, it gets converted into heat that is transferred into the pool water. In the market, you’ll find covers of different colors at large. You will find others in the dark, they are designed dark to enable them easily to absorb sunlight, convert it into heat and transfer it into the water, thereby maintaining the water warm.

There are also other covers made of inexpensive clear plastic. They are designed using a special material that stores sunlight as heat. Air bubbles will work as insulation to trap heat in water and thus maintain the pool warmer.

What is The Right time to Use a Solar Pool Cover?

Most people cover their pools only during the night. However, this is not correct, especially when you’re aiming at retaining water warmer. It’s advisable to cover up your swimming pool any time the pool is not in use. At night, the pool will cool the fastest since there is more cold air around. This is a similar case during the winters; there is colder air both during the day and night. Therefore, you’ll need always to use your cover during these times to hold that heat. Overall, solar covers should be used any time the swimming pool is not in use.

Now, you’ve learnt the types of solar pool covers. You need to know how the covers help to keep the pool water warmer. Below are three things that solar covers do;

The solar covers have the potential to heat pool water in different ways, retaining heat and reducing evaporation. But then, how is this achieved?

Solar Covers Prevent Evaporation.

Evaporation is the leading cause of heat loss in swimming pools. During the day, water will absorb UV rays ad convert it into energy. During evaporation, a significant amount of energy is used up, thereby decreasing the pool temperatures. Let’s have an example if a pool is now at 80 °F and it happens that a pound of water has evaporated, in this scenario, water will lose approximately 1048 Btu of heat. Look at this instance; try to compare it with the amount of heat that is used to heat pool water even at one degree. Generally, it takes 1 Btu to create up heat of1degree in a pool. As you can see, heating up water can be a long-awaited thing compared to losing the already generated heat.

This is why most pool owners are advised to use solar covers, especially during the wintertime and at night. Solar covers will help you get your pool water warm by preventing evaporation from occurring. Besides this, solar covers are designed effectively to heat pool waters.

Heat retention 

Compared to water, solar covers absorb much sunlight at ago. Despite the large surface area of the pool, not much of sunlight hitting the water gets converted into heat. The sun’s UV rays can penetrate through the water, but water won’t do much to absorb and retain the heat. However, solar pool covers are capable of absorbing and retaining the heat that gets transferred to the water below later.

Solar pool covers can heat pool waters to around 12 degrees; this is a significant free heat value we get from direct sunlight. They have tiny air pockets that capture and store heat from the sun which it’s transferred to the pool. Solar pool covers act as insulators to prevent heat from escaping from the water.

For indoor pools, heat loss can arise through the cooler air in that environment. Pool covers in this case act as the right way to keep the water warmer. During the night, the air around is cooler compared in water, so without a cover, the water will lose a significant amount of heat in the night hours.

Besides the above benefits of the solar covers, they also help to reduce chemical depletion in the pool. Evaporation means loss of water into the air; therefore, some amount of chemical will end up in the air during such an event. Solar covers can reduce the pool chemical consumption for up to 60% by preventing water from evaporating. Exposure of the water to the sun results into a quick break down of chemicals in the pool, which will need you to replenish them more often to maintain your water safe for swimming.

Now, after we have learnt the significant benefit of solar covers in heating our swimming pools, we need to know how fast the covers take to heat a swimming pool. Are there any factors that affect the efficiency of heat retention in pool waters? Read on to learn more.

How Fast Solar Covers Heat a Pool

The rate at which water is heat depends significantly on the intensity of the sun and the period the water receives direct sunlight at large. Besides this, the size of your pool and the weather condition of the area you live in other dependable factors. Generally, it takes the cover 12 hours to heat pool water by 5 degrees. However, to attain this measure, you need to cover up the pool as much as possible and also the pool needs to get at least 6 hours of sunlight every day.

Conclusion

Solar pool covers are the ideal solution to keep your pool water warm. They prevent evaporation from taking place and also retain heat that’s already in the water. You always need to cover the pool whenever it’s not in use so that you don’t give room for the heat to escape. Besides, you should also ensure to cover up them during the nights since a significant amount of heat is lost during the night hours. So, let’s keep our pool water warm to enable us to enjoy swimming exercises whenever we need it.
