Will a Pool Heat Up Faster With the Cover On?

A pool cover is an important investment for any pool owner. Not only does it help keep your pool clean and free of debris, but it also helps to reduce chlorine loss. But will a pool heat up faster with the cover on?

Putting a cover over your pool will cause your pool to heat up faster. This is because a pool cover blocks the pool water from direct sunlight. A cover prevents evaporation, reducing the time and energy it takes to heat your pool. In addition, a cover helps insulate the pool and keep the heat in.

Keep reading for a rundown of the reasons why a cover can make your pool heat up faster, as well as tips on how to heat your pool quickly and efficiently.

Reasons a Covered Pool Heats Up Faster

Here are a few reasons why a cover can help heat your pool faster:

The Cover Blocks the Wind

Wind can significantly impact the temperature of your pool water. If the wind is blowing, it will cool down the water in your pool by increasing the rate of evaporation.

However, if you have a cover on your pool, the surface will be protected from the wind, and the water will be kept warm. The cover acts as a barrier, stopping the wind from reaching the water. As a result, the water will be shielded from the cooling effects of the wind, allowing you to heat your pool without any interference.

The Cover Prevents Evaporation

Evaporation is another factor that can cool down your pool water. The process involves the movement of water molecules from the pool and into the air. When this happens, the temperature of the water in the pool will drop.

A cover can help to prevent evaporation by trapping the water molecules inside the pool. That will stop them from moving into the air, meaning less heat will be lost from the pool. As a result, your pool will heat up faster.

The Cover Traps Heat From the Sun

A pool cover is a great way to trap heat from the sun and keep your pool warm overnight. Without a cover, the sun’s rays will heat the water during the day, but as soon as the sun goes down, the temperature of the water will start to drop.

A cover on your pool will help trap the heat from the sun, so your pool will take longer to cool down. That will give you a head start on heating your pool the next day.

The Cover Insulates Your Pool

An uncoated or uncovered pool is like an open container of cold water sitting out at room temperature—without a lid to insulate it, the cold water will quickly reach room temperature.

A covered pool is more like a container of cold water with a lid—the cold water will take longer to reach room temperature because it’s being insulated by the lid (or cover).

So, a cover acts as an insulator for your pool, trapping the heat in and stopping it from escaping. As a result, your pool will heat up faster and maintain its temperature for longer.

Ways To Make Your Pool Heat Faster

Now that you know how a cover can help your pool to heat up faster, here are a few other tips that will help you heat your pool quickly and efficiently:

Turn Up the Thermostat

One way to make your pool heat faster is to turn up the thermostat. That will cause the heater to work harder and the temperature of the water to rise more quickly.

However, it’s crucial to remember that doing that will also increase your energy bills. As a result, you may want to do this for short periods when you absolutely need to raise the temperature. If you’re patient, you can save money by slowly heating the pool over a more extended period.

Use Black Plastic Sheeting 

If you want to heat your pool quickly, using black plastic sheeting is a great technique. Black plastic sheeting helps absorb heat from the sun and transfer it into the water. For best results, you should place the black plastic sheeting over the entire surface of the pool. That will help ensure that the maximum amount of heat is absorbed and transferred into the water.

Alternatively, you can use a clear solar cover to achieve the same effect. Solar covers are made of a material that allows sunlight to pass through but prevents heat from escaping. That makes them ideal for heating up pools quickly.

For starters, check out Doheny’s Clear-Tek Micro-Bubble Solar Covers on Amazon.com. They’re designed to minimize heat loss while increasing heat absorption by 15%-25%, making them a great yet affordable option for quickly heating your pool.

Use a Solar Pool Heater 

A solar pool heater is a great way to make your pool heat faster, as it uses the sun’s energy to heat the water. Solar pool heaters are typically very efficient and can help raise your pool’s temperature by several degrees. These heaters work by collecting solar energy from the sun and using it to heat a fluid that is then circulated through a series of coils.

The heated fluid then transfers its heat to the water in your pool, causing the temperature of the pool water to rise. Solar pool heaters are an excellent option for those who want to swim in warmer water without having to use traditional heating methods, such as gas or electric heaters.

Use a Heat Pump 

A heat pump is another method that you can use to make your pool heat faster. A heat pump works by taking heat from the air and transferring it into the water. That’s a very efficient way to heat your pool and can help you save money on your energy bills.

Besides being efficient, heat pumps are also very versatile: you can use them to cool your pool in the summer and to heat it in the winter. That makes them an excellent option for those who want to be able to swim all year round.

The Bottom Line

As you can see, there are a few different ways a cover makes your pool heat up faster. A cover can help your pool maintain its temperature for longer by trapping heat and preventing evaporation.

If you need to raise the temperature of your pool quickly, you can use a solar cover or black plastic sheeting to absorb heat from the sun and transfer it into the water. Alternatively, you can use a heat pump to take heat from the air and transfer it into the pool.
