Best Solar Pool Heaters ReviewsWe all love to hang around the swimming pools in our backyard. The winter often can put a dampener on these plans. Nobody likes to jump into a swimming pool of ice-cold water. The problem during the winter is once the sun goes down; the water in the swimming pool can get pretty cold.

The solar pool heaters can solve this problem. While there are some other options available as well to increase the temperature of the swimming pool but my most of them are pretty expensive, the cost of heating the swimming pool with those traditional methods is directly proportional to the size.

A much more affordable option is to use the solar pool heater. The heater directly gets the energy from the sunlight. Thus, you can minimize your electricity and fuel bills. It heats the pool without incurring a significant amount of expense.

• The size of your swimming pool:
Choose The Best Solar Pool Heaters for Above Ground & Inground Pools

The size of your swimming pool will decide the type of solar heater which you choose. The bigger swimming pools need more powerful solar pool heater. You have to always look at the size of the swimming pool which the solar heater can heat before buying the right one. You should not shy away from purchasing multiple solar panels if needed.

When you compare the different solar heaters, it is essential to find out the capacity of the pool which they can heat. If you use the same pool heater for a bigger pool, the temperature difference will be negligible. The efficiency of the pool heater reduces. Irrespective of the sunlight available, the pool heater will not be able to heat your pool. Thus, it will be meaningless to install it for a bigger pool than recommended.

• Installation:

You have to find out about the installation procedure of the pool heater. If an expert is required to do the same, it can be an expensive proposition. If on the other hand, the solar heater comes along with proper instructions and is easy to install, you can do it yourself. You need not then spend money on hiring an expert.

When you’re not familiar with the installation and opt to get it done by the expert, any small problem will require you to call the expert. The maintenance cost of the pool will increase significantly. In the longer term, it can end up being much more expensive than even the utility bills for traditional heating. That is why it is necessary to pick the pool heater which you can install yourself.

• Temperature:

Ideally, most of the solar swimming pool heaters can increase the water temperature by 5° F to 10° F. None of them, however, can raise the temperature by up to 15° F. You have to find out the exact capability of the swimming pool heater before taking a call.

You can increase the water temperature by more than 7°F only when you have multiple solar panels set up. When a single solar panel is set up, it is tough to raise the temperature by such a significant amount.

• Type of pool:

There are different swimming pool solar heaters available for in-ground pools and above ground pools. Depending on the type of swimming pool which you have, you have to choose the pool heater accordingly. Most of the pool heaters mention on the package whether they are compatible with the in-ground pools or the above-ground pools. There are a few options which are compatible with both the type of pools.

During the winter season, the ground attains a lower temperature as compared to the air. The in-ground pools are in contact with the cold ground. Therefore, In-ground pools require more heat. The pool heaters which can heat in-ground pools can generate such a significant amount of heat.

• Installation surface needed:

Most of the pool heaters can be set up on any flat surface. There are however a few which can be set up only on the roof. You have to look at the area which is available to set up the pool heater. Once you take that into account, it will be easy for you to decide whether you can comfortably accommodate the pool heater or not.

Ideally, you should pick a pool heater which does not require a particular surface like a rack or the platform to install it. When the installation is possible on a variety of different surfaces, it is easy to use.

• Hardware:
