How Fast Does A Solar Cover Heat A Pool


A solar cover is an excellent weapon in any pool owner’s toolbox for keeping the ideal water temperature. It not only aids in heat reservation but also utilizes the sun’s power to heat your swimming pool. This article will provide all the crucial details you require if you wonder how quickly a solar cover can heat your pool.

Describe the solar cover.

A solar cover is a sizable sheet made of hardy, UV-resistant cloth. It is also referred to as a solar pool cover or thermal blanket. Its purpose is to absorb sunlight while floating on the water’s surface. The cover is a barrier, keeping heat inside the pool while allowing sunlight to pass through and warm the water below.

Pool Solar Covers: 

There are several different pool solar covers on the market. Typical possibilities include:

Bubble Covers: These covers look similar to bubble wrap and feature tiny air spaces that improve insulation and heat retention.

Liquid solar covers: These items don’t have a physical covering; instead, a thin coating of liquid chemicals forms on the water’s surface to prevent evaporation and heat loss.

Insulated coverings: Constructed with several layers of insulating material, these coverings are perfect for colder areas and offer good heat retention.

How Fast Will a Solar Cover Warm Up My Pool?

The following elements affect how quickly a solar cover heats your pool:

Sunshine Intensity: The solar cover will be able to absorb more heat the more intense the sunshine. As a result, pools in areas with more sunlight typically warm up quicker.

Ambient Temperature: Warmer air temperatures facilitate quicker heat transmission, facilitating quicker pool warming by the solar cover.

Cover Quality: The solar cover’s thickness and quality can affect how well it heats. The pool tends to heat up more quickly under thicker coverings with superior insulating qualities.

How Quickly Does the Sun Heat a Pool?

A pool can naturally heat up when exposed to direct sunshine in addition to employing a solar cover. The size and amount of sunshine the pool receives are significant factors in the heating rate. Under ideal circumstances, an uncovered pool may typically warm up by 1 to 2 degrees Fahrenheit every hour.

Does the Pool Remain Warm at Night Under a Solar Cover?

A solar cover is efficient at keeping heat inside during the day, but it might be warmer at night. Although the cover is a barrier to reduce heat loss, the pool’s temperature may gradually drop without direct sunshine. Consider employing extra heating techniques, such as a pool heater or a heat pump, to keep your pool warm at night.

What Cover Size Should I Purchase?

The efficiency of a solar cover depends on the size that is selected. Choose a cover that barely exceeds your pool’s size after measuring it. Doing so ensures appropriate coverage and heat loss from unprotected areas is decreased.

Can My Solar Cover Be Cut?

A solar cover can be shaped to fit the size and shape of your pool, yes. This is especially helpful for smaller pools with odd forms. Use a utility knife or sharp scissors to precisely trim the cover to the required measurements while following the manufacturer’s instructions.

Do I Need to Cover the Whole Pool?

A solar cover to enclose the pool ultimately ensures optimal heat retention, but it may not be feasible or essential for everyone. A few pool owners decide only to cover a portion of their pool, leaving some areas accessible for swimming. Consider your unique requirements and preferences when choosing how much of your pool to cover.

(FAQs)-Frequently Asked Questions

Does a solar cover allow me to extend my swimming season?

By capturing and using the sun’s energy to warm the pool water, a solar cover can help you extend your swimming season and enjoy your pool for longer.

Do sun covers work with pool heaters?

Certainly! Energy use can be considerably decreased by using a solar cover with a pool heater. Faster heating and cheaper energy expenses are achieved because of the cover’s ability to retain the heat produced by the heater.

How long should my pool’s solar cover be left in place?

It is always advised to keep the solar cover on your pool. This lowers evaporation, maintains water temperature, and helps keep debris minimal.

Do solar coverings respect the environment?

Solar covers are environmentally friendly since they use solar energy to heat pools rather than relying exclusively on electricity or gas. They lessen carbon impact and energy use.


 Purchasing a solar pool cover is wise if you want to enjoy warm water while reducing energy bills. While the heating rate may vary depending on the amount of sunlight, the surrounding temperature, and the quality of the cover, a solar cover effectively traps heat and speeds up your pool’s natural warming process. Choose the appropriate size, consider cutting if necessary, and use a heated pool all swimming season long.
