It comes with a 4′ x 20′ Wide Solar Collector which must be placed in an open space with un-blocked sunlight.

With the help of a pump, the cold pool water flows through the collector, which is sitting in the sun, and thus gets heated.

At its best, this solar heater is capable of raising the water temperature by 5-7 degrees F each day.

What makes this solar heater unique is the presence of an On/Off switch on the heater’s body. If the weather is cloudy, you can turn the handle and switch the heater off.

H2 – Choosing the Best above ground pool heater – The Ultimate Buying Guide

With a range of options available from a dozen different brands, choosing the right heater for your above ground pool can be an exhausting task.

To make the selection process more challenging, there are quite a few different types of heating methods available.

But don’t worry! We’ve performed hours of research on your behalf to bring you this guide so you can choose the best kind of heater for your above ground pool with confidence.

Now, this might not be the most interesting topic out there, but it sure is an important one.

Let’s begin by laying down all the different kinds of heaters that are available on the market:

  • Solar heaters
  • Solar Covers
  • Electric heaters
  • Gas heaters
  • Wood heaters (For the sake of completeness)

Now, let’s take a brief look into each of the above-mentioned heater categories.

Solar Heaters

With millions of Americans switching to solar systems to heat the water used in their household, solar heaters have been growing in popularity over the years. After all, green energy is the future.

As the name suggests, solar pool heaters use the energy from the sun to heat the pool. Since solar energy is available free of cost, solar heaters are the most efficient heating solution available with the lowest (almost zero) annual operating cost!

Although cheaper in the long-run, you’ll have to spend more money upfront to buy a solar heater and the various components required to set it up (If you decide to go for a sturdy and glazed collector).

However, because you’re saving on the fuel/electricity charges, this heater provides a payback of between 2-6 years.

If you do not want to spend a lot on a high-end solar heater, you’d be pleased to know that there are a lot of budget-friendly options available too! Although these might not be as durable or efficient as the higher-end heaters, they do however offer great performance for the price.

If you live in a place that gets decent sunlight and don’t mind the high initial price, a solar heater is a perfect choice for you!

Price range (excluding installation): $1,000 – $5,000

Solar Covers

Evaporation of the pool water is the biggest source of energy (heat) loss in pools. The higher the rate of evaporation, the colder your pool becomes.

A solar cover — also called a solar blanket — is a plastic/vinyl sheet that is spread on top of the pool to minimizes the loss of heat due to evaporation.

Like solar heaters, solar covers are dependent on the sunlight to heat, or rather, preserve the heat of the pool. But compared to a solar heater, a solar cover is much more pocket-friendly and does not require any extra components.

These come in two variants:

Cheaper Plastic covers.

Slightly more expensive but very durable Vinyl cover.

I would always recommend choosing a vinyl cover instead of a plastic one as vinyl covers last much longer and there isn’t a lot of difference in their prices.

If you live in a place that gets good sunlight during the day and the temperature does not drop significantly in the evening, a solar cover might just be the best solution for you!

Price range (excluding installation): $150 – $800

Electric heaters

If you live in a place that does not get enough sun during the day and the evenings are especially cold, the solar option mentioned above would not be a good choice. In this case, you’ll have to rely on external sources of energy – Electricity or Gas.

An electric heater uses electricity to heat the water. Hence it can be used in any season or climate without any external dependency.

There are two types of electric heaters:

First is the tankless electric pool water heater

The second one is an electric pool heat pump.

A tankless water heater is much like the heater that you use in the bathroom. The heat is generated from a heating element present inside the heater.

These are less expensive initially but are not energy efficient and can cost 6-7 times more than a heat pump in operational cost.

A heat pump, on the other hand, collects the heat from the surrounding air – with the help of a compressor – and transfers it to the pool water.

Compared to tankless water heaters, heat pumps are much more environmentally friendly and efficient. They have low annual operating costs and can last you a decade!

The only shortcoming of a heat pump is that the surrounding air temperature should at least be 45 ºF for it to work efficiently. However, this does not mean that they do not work in colder temperatures!

They will work at any temperature, but the efficiency of the heat pump comes down with a decrease in the temperature.

Price range (excluding installation): $1,000 – $10,000

Gas heaters

Gas heaters are the most popular heating solution amongst pool owners as they are comparatively faster than the fastest than others and can work throughout the year.

These heaters run either on natural gas or liquid propane which are used in the combustion chamber to produce heat.

Gas heaters are notorious for their high annual operating costs and low energy efficiency. They also need to be refilled regularly with either natural gas or propane.

Why are these such a popular choice despite the above-mentioned drawbacks?

Gas heaters are a popular choice amongst those who live in a relatively warm place, do not use their pool frequently, and only require heating their pools for short periods. In this scenario, the low energy efficiency of this heater does not make much of an impact on the costs.

Price range (excluding installation): $900 – $5,500

The Best Above Ground Pool Heaters – Frequently Asked Questions

What type of heater should I buy for my above ground pool?

This is by far the most common question that I get asked when it comes to pool heaters. Unfortunately, there is no definite answer to this question just like there’s no one size fits all.

There are a bunch of factors that work together to decide the best heating solution for your needs.
The most important of which is your geographical location.

Do you live in a place that gets decent sunlight (which reaches your pool) and remains quite warm during the summers?

If so, then you probably wouldn’t require heating the pool water a lot and could just get a solar cover for your pool and see if it meets your requirements. This would be the most cost-effective solution in your case.

If you live somewhere cold but get decent sunlight during the day, then you could get your self a solar heater along with a solar cover. This would be the most cost-effective and energy-efficient solution. You can use the solar heater during the daytime to heat the water and then cover the pool with a solar cover to retain the water heat for later use.

If you live in a place that remains cold and does not get enough sunlight during the day, then the solar options might not be enough for your needs.

In such cases, you have two options: a heat pump or a gas heater.

If you don’t use the pool very frequently and have a gas line at home (or access to propane gas), then a gas heater would be a good choice. It’ll heat the pool quickly and won’t cost you a lot.

If you do use the pool quite often, then a heat pump might be the best choice for you. It may be a bit heavy on the pocket in the short-term, but it is a very good long-term solution with low operation and maintenance costs.

I would also suggest getting a solar cover along with the heater to retain the water temperature for a longer period and thus reduce your heating costs

How much does an above ground pool heater cost?

As I mentioned previously, the cost of the heater will depend on the type of heater that you plan to get. But below is a rough estimate of the prices of various heaters:

Note: These prices do not include the installation charges.

CategoryPrice Range
Solar Covers$100 – $1000
Solar heaters$1,000 – $5,000
Electric heat pumps$1,500 – $10,000
Gas heaters$1,500 – $6,000

How does an above ground pool heater work?

The heating mechanism depends on the type of heater in question.

A solar heater works by converting the energy from the sun into heat.

A heat pump, with the help of a compressor, takes the heat from the surrounding air and transfers it into the water.

A gas heater has a combustion chamber present in it. This is where the gases are burned to produce heat which is then used to heat the water.

What size above ground pool heater do I need?

The size of your heater depends on the size and volume of your pool. The higher the size of your pool, the larger capacity heater you’ll require.

Take a look at the below table to get an estimate of the heater capacity with varying pool sizes.

BTUGallonsSquare Feet
100,000 – 200,0001,000 – 10,000300
200,000 – 300,00010,000 – 20,000500
300,000 – 400,00020,000 – 40,000800
400,000+40,000 – 80,0001200

Electric vs Gas heaters, what’s the difference?

If you’re short on budget and don’t use your pool often, then a gas heater might be a good option.

If a high upfront cost is not an issue, then I would recommend going with an electric heat pump. Electric heat pumps offer a great long term value, with tiny annual maintenance costs and high energy efficiency.

Are heaters safe for Intex pools?

Most heaters are safe and work well with Intex pools. However, some of these options might just be overkill given the comparatively smaller size of Intex pools.

My suggestion would be to get a solar cover for your Intex pool (if sunlight isn’t an issue) and see if it’s enough for your requirements. If it does not meet your requirements, then you can go a level up and get a small heating thermostat or a solar heater depending on your requirement.

Do solar heaters work well for above ground pools?

Yes, a solar heater can work brilliantly well, provided they get enough sunlight. These may not be the right choice for you if you do not get sufficient sun during the day.

Are above ground pool heaters worth it?

It depends on your personal preference. I’m one of those who almost always prefers having warm water in their pool. So for me, a pool heater was a no-brainer and absolutely worth it!

If you’re worried about the cost, I would suggest you test the waters (pun intended) with a solar cover. Not only do they help preserve the heat in the water, but they also conserve water and reduce the pool’s chemical consumption.
