What to Consider for the Best Solar Heaters for Above Ground Pool

Solar Heater for Above Ground Pool

While there are not so many options for pool solar heaters, well, you still need to consider the available options keenly. Do not pick just the first one that you come across.

Here are a few important factors to consider …

Size

When it comes to the best solar pool heater, size matters a lot. In addition, the bigger it is the faster it will heat the water. You see, the water from the pool has to pass through the solar heater to collect heat. Therefore, it will keep circulating that way until all the water is warmed. In the same line, you can see that if the solar heater is small, it will take too long.

Mostly, the common above ground solar heater measures about 20 feet by 2 feet. However, some measure 20 feet by 4 feet. Of course, what you buy depends on the size of your pool.

Type of Solar Heater for Pool

There are different designs for the solar heaters for pools. For instance, the most common ones are the solar panels that roll out and stretch to their full size. Furthermore, these heaters come rolled up and then you have to unroll them before installation. While they feel a bit flimsy, they are quite good and durable.

In addition to the panel types, there are dome swimming pool heaters. Indeed, these ones look like domes. However, like the panel designs, they also connect to your available pump. In addition, they come with their installation accessories, so you probably don’t have to get anything from the store.

The third type of solar heater for above ground pools is the solar rings. However, these are not common at all. For instance, in this article, we reviewed just one of them. Despite this, they are efficient and they act as a pool cover.

Price and Warranty

We always say that you should consider the features before the price. However, it eventually comes down to the price.

On the same note, these heaters can cost a substantial amount of money. Therefore, make sure that the features are worth the money that you are paying for it. In addition, ensure that it comes with all installation accessories, including Teflon tape.

The price of the solar pool heaters depends on a few important things. For instance, bigger heaters will cost more than small ones. In addition, do not let any manufacturer cheat you into buying a small solar heater.

Some solar heaters for pools come without warranty information. However, for the ones that do, most of them have a 12-month warranty. Therefore, always opt for one that has a warranty rather than one that does not.

Ability to warm the water

Well, to tell you the truth, these solar heaters for above ground pools will not make the water hot. However, they will make it warm enough to swim even in the cold season.

Therefore, most of them promise to raise the water temperature by 5 to 10 degrees Fahrenheit. Likewise, some do slightly higher or lower than that. Of course, this also depends on the amount of sunshine that is available per day. Therefore, on cold days, you may not get enough warmth.

The above ground solar heaters should be easy to install. However, this is not something that you can do straight from your head. Therefore, you need a package that comes with a proper installation guide. Some might be poor translations from the Chinese language and such can be a bit of a bother.

Another thing that you should look for before you make your order is the installation accessories. For instance, these include hoses, elbows, end caps and others. Likewise, if the package does not have such, the manufacturer should disclose that information and advise you to buy separately.
