Read to learn about the 6 most efficient and durable solar pool heaters for inground pools so that you can make the best buy for your pool. 

Solar Pool Heaters For Inground Pools- Advantages

Before jumping into the topic you must know how beneficial these solar heating systems are, and why they are worth your investment. 

Heating System That Is Long Lasting

Solar heaters are generally subject to meticulous examination and testing before being released into the market. That is the reason why majority of these products are highly durable and efficient in functioning. Most of these solar heaters are made using pre-compounded polypropylene, which is made to cope with unfavorable conditions when placed on the roof, including the damaging UV rays of the sun. 

Pricing Is Reasonable

These solar-powered heaters are relatively cheaper than most other varieties of pool heater. Because the energy of the sun is used to power these heating systems, you save an impressive amount of money, making it one of the most demanding features of such heaters. 

Eco-friendly Heating

The unique feature of solar heaters for pools is that they don’t release damaging or harmful items into the air, and they don’t require fuel for operation like the pool heaters that run on gas. After installing a solar-powered heater all you do is enjoy a swim in your swimming pool while the heater runs on the sun’s heat without affecting the environment adversely. 

Solar Pool Heaters For Inground Pools- Buying Guide

Before purchasing the most-appropriate solar-powered pool heater for your inground pool, these are the primary features to look for:

What Size It Comes In

While the large-sized solar-powered heating systems provide faster pool heating and have a greater amount of exposure to sunlight, they are additionally more space-occupying. The smaller heaters, on the contrary, are less space-occupying but less effective when it comes to functionality. Your choice of a product must be based on what you need exactly in terms of functionality and how much space can you afford to assign for the solar pool heater. 

What Warranty It Comes With

Since the solar-powered heating systems for pools are outdoor equipment, they become vulnerable because of being exposed on a continuous basis to unfavorable climatic conditions. The risk of damage to such heaters is high despite them being sturdy and lasting. That’s why you must opt for a solar-powered heating system that includes a maximum period of warranty. 

How Efficient It Is

Of course, the efficiency of a solar-powered pool heater is primarily the reason for buying it. Equipment that is more efficient can easily heat up pools at a faster rate, whether it is inground or above the ground. However, if the pool you own is small, you can avoid looking for the more efficient pool heaters.
