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.

Solar pool coverings on your pool are just like enormous sheets of bubble wrap. The pool stays hot for a long time because the bubbles retain the heat from the sun. Solar covers help the pools to retain heat by shielding the water from chilly night time air in addition to warming pools for your day time swimming.

And now we have a question about heating cover : How much of a pool can a solar cover heat? While on a sunny day, a fully covered pool may typically gain in temperature by 11 to 15 degrees in roughly 6 hours.

Do Solar Pool Covers Work in Queensland?

The next question is “How well-functioning are solar pool covers?” Solar blankets would have perished long ago if they did not work effectively. Solar blankets or cover can cut a number of  heat loss and pool water evaporation by up to 94%, by 2016 Cal Poly study. A solar pool cover can heat water up to 10 degrees in Queensland. 

With the experts ( 2014 study by Collage), pool covers can decrease energy costs by as much as 29.99%. In contrast, a 2012 Michigan Energy Office study tells us that pool covers save energy expenses by about 50%. The efficiency of a solar pool cover helps with the amount of pool coverage.

On the side the most efficient solar cover for heating a pool is a solar cover known as solar  blanket.

A solar blanket is able to raise the water temperature of the whole pool by up to 10-15 degrees in a day, it depends on the weather. On average, expect about a 5-degree can be increased on the first day. If we cover a pool all around then it can be warm in 6 hours in Queensland, according to the experts.

If the sun stays shining for  Three days it will raise the temperature by 7 to 10 degrees. This thing depends on several things, for example the cover’s thickness, the exterior temperature if it is an outdoor pool or for the internal temperature and  if it is an indoor pool than how much direct sunlight your pool actually receives, and No matter, not you’re using the solar cover in conjunction with a solar pool heater.

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.

By considering the shape of your swimming pool, you need to measure the longest part and the widest part of your pool.  Then using those measurements, go for a tiny bit larger.  Remember, you are going to be cutting your pool cover to fit.  Some different solar cover sizes are 12×24’, 15 x 30’, 16 x 32’, 18 x36’ and 20 x 40’ these are the common sizes of a pool.  This doesn’t mean there are no other options available out there.

A Must with a Swimming Pool Heater

In our opinion, a solar cover is a MUST need if you own a swimming pool heater.  The reason is that you lose SO much heat off of the surface of the water. Around 5 degrees a night. Yes, some of the heat can be absorbed into the swimming pool’s surface, and some condensates, but most of the heat is lost from evaporation. 

You already have spent thousands of your costs on the pool heater itself and have to pay for the gas to run it and enjoy it.

Dirt and Debris
