5 Ways To Heat Above Ground Pool (With & Without Heater)

With a pool, you can enjoy swimming all year long. But there is nothing worse than jumping into a chilly pool when the air temperature is 30 degrees outside. You can heat your above-ground pool by just installing a heater. This post will detail the steps to heat and winterize your above-ground pool.

The best choice is solar heaters. These work by converting sunlight into heat. This is the most cost-effective way to heat your pool, and it has a low impact on the environment. Other popular choices include natural gas heaters, propane heaters, and electric heaters. 

Pools keep you cool during the hot summer months and help you relax. A centerpiece of most backyards, heated pools provide relief from the chilly winter months. In this article, we’ll look at how to heat in-ground and above-ground pools including how to heat your own with a DIY heater project and a list of indoor and outdoor options for easy installation.

Best Heater Choices For an Above-Ground Pool

Pool heaters are important for a majority of pool owners, but it can be difficult to find a perfect heater for an above-ground pool. There are many types of them and they each have their own pros and cons. Some of them might be better than others but only if they are installed in the right way and used as they were intended to be used.

Solar Heater

Above-ground pools are great for an addition to your backyard. However, they require a lot of maintenance and can be hard to heat. With solar heating, you get the best of both worlds. This is a low-cost technology that allows you to use the sun’s natural energy to heat up your pool.

Solar heaters are the most popular choice for heating an above ground pool. They are direct and energy-efficient.

The solar collectors can be mounted on the pool or on a roof, depending on the design of the system. Solar panels collect energy from the sun and transfer it to water that heats up.

The solar panel heats up because of sunlight, which is converted into thermal energy by a process called photovoltaic (PV) conversion. The water is heated with a pump and circulated through pipes before it enters the heater unit, which extracts heat from the hot water.

To use any kind of solar heater, you need to have consistently sunny weather and during this time collect water with a pump and circulate it through these pipes before it enters either a gas or electric heater to extract heat from it (this extractor is often embedded in the same unit as your collector).

Electric Heat Pump

The electric heat pump for swimming pools is a device that can be used to heat the water in a swimming pool. The device is powered by electricity, and it has a fan that distributes the heated air into the pool. An electric heat pump is a versatile, low-cost, and efficient heater option. They work by transferring heat from one place to another. 

This can be transferred from the air, water, ground, or solar panels. Electric heat pumps are highly efficient as they use electric resistance heating that doesn’t need any fuel to operate. This makes them low cost in regards to both installation and running costs.

The main feature of this device is its ability to heat water without using gas or oil. This means that you do not have to worry about running out of fuel while using your pool heater, which can be very frustrating if you do not have access to more fuel immediately.

The system uses fans and pumps to move air through coils within the device. The coils are made from metal or another conductive material, like ceramic or plastic. 

They are then connected to an electrical source so that they can draw power from it and begin heating up immediately after being turned on by someone who wants their pool heated up before going swimming outside during summertime days when temperatures rise above 100 degrees Fahrenheit (38 Celsius) outside during daytime hours).

Best Non-Heater Options To Heat an Above-Ground Pool 

Heating a pool is a lot of work. There are many different ways to heat a pool, but the most common way is with a heater. But what if you don’t want to deal with the hassle of keeping up with a heater? Or maybe your budget just doesn’t allow for it?

Luckily, there are other options. These choices are typically easier, cheaper, and don’t require a heater. Let’s take a look at some of the best non-heater options to heat an above-ground pool.

Use a Solar Cover 

A solar cover can be used as a safety feature and can also help keep debris out of your pool. If you have an above-ground pool, it’s important that you use these covers to protect your investment and keep your family safe.

A solar cover is made of polyethylene terephthalate (PET) which is completely safe for use around children and animals. The material has been tested and proven to be durable and long-lasting so that it won’t wear down easily over time. The material also helps prevent algae growth which can cause damage over time if left unchecked.

The cover will trap the sun’s heat, which can raise the temperature of the water by as much as 20 degrees. The hotter the water, the more comfortable it is for swimmers and your pool’s overall lifespan will increase. But how long does it take for a solar cover to heat up an above-ground pool?

The time it takes for your solar cover to heat up an above-ground pool depends on several factors:

  • the size of your pool
  • Your geographic location (warmer climates will require less time)

Try Solar Sun Rings

These solar sun rings are great for non-heater options and can help you keep your pool warm without using any electricity. They’re easy to install and use, so there’s no need for any tools or additional costs.

The solar sun rings attach easily to the top of your pool and will begin heating it up immediately. You can use them year-round and they’ll keep the water temperature from dropping below 75 degrees all the way through the winter.

Solar sun rings are small discs that fit in the center of your pool and absorb heat from the sun. They are made of a special material that helps them retain heat even when it’s cold outside. You can get these rings in different sizes depending on how big your pool is: there are options for pools up to 20 feet wide, as well as larger ones for pools up to 30 feet wide (the largest size).
