Spread the love

The sun has been serving us since the existence of this universe. New technology has made our lives simpler than before through solar products. Now, we can enjoy swimming with solar heaters for above ground pools. It wasn’t possible a few years back.

These heaters work through pool pumps and filters which send water back to the pool after passing it through the panels. The entire process raises water temperature like from 6 to 10 degrees Fahrenheit.  

Most solar heaters for above ground pools have two solar panels but you can also buy more if your pool is large. These heaters are suitable for different pools and people of all age groups find them useful.


Buying Guide

Only the swimmers would understand the importance of the solar heaters for above ground pools because they miss when they can’t swim due to cold water. The heaters can also work for in-ground pools depending on the manufacturing. But, special heaters are also available only for in-ground pools.

The heaters have solar panels of up to 20 feet to 50 feet long and even more than that. Some heaters are only good for square or rectangular pools, but some are suitable for both round and linear pools. These heaters work through built-in hoses and the users can connect them with a pool pump.

The entire heating unit functions by cycling the water from the pool to the solar panel and to the pool again. The better is the header and the pump better would be the function of the heater. Generally, it heats up water from 10 to 15 degrees F, however, the panel’s sun exposure is the most important factor for heating.

Now, the issue is that so many products in the market are overwhelming us so how to have an effective heater. We are giving you some features for a wise investment in a long-term solar heating unit.

The Material

Solar panels are generally made of polypropylene which is high-grade in its function. These panels are waterproof and the rain can’t affect them so they would last for long. If you see other materials, explore their qualities before buying that product.

Purpose of Heater

The basic purpose of the heater is to give you warm water during spring or fall or even in winter. It should increase the water temperature up to 10 degrees that is the minimum level as some heaters also provide 15 degrees F temperature. Read the specs to see what temperature heater offers.

Solar Heater Size

Buy a heater that is suitable for your pool size. Also, look at its shape to see if it’s good for a round pool or for an oval and rectangular pool. Some heaters suit all shapes but some are for specific pools. Also, see if there is enough space around the pool to keep a long panel.

Conversion Rate

Solar products’ basic function is to convert the solar heat to the power that can light up a fixture or can heat water. So, the conversion rate of the solar heater should be high to get the desired results.

Check for Pump

Ensure that the heater would be compatible with an existing pool pump. As if it is not so, you will have to buy another pump that would be an added cost. The pump should also be powerful enough for water flow and should work fast.

Check for Hose

In general, the heaters have built-in hoses so check their quality. Make sure that leaks don’t happen in the unit as it would become a waste product. Certain companies make poor solar heaters that develop leaks after a year or even before that.

 Right Installation

Almost all the products have an instruction manual with them, so read it before installing a heater on your own. If you can’t install it, get a professional installer. A wrong installation would not bring the right outcome. Make sure, all accessories are there with the product or you will have to buy an installation kit.

Suitable Area

A solar product can’t work if it is not exposed to the sun. You can’t put the solar heater near a covered pool. The panel must face the sun directly so it can absorb the maximum sunlight and convert it to the power that gives us hot water. It won’t work in the clouds or areas where the sun appears only for a short time.

Find the Warranty

Only a few companies offer a refund upon an issue with the heater. Read all the details of the product including its warranty time. Some products offer only a one year warranty, but some offer five years warranty. Spending some money today would prevent the maintenance cost that is likely to happen in the future.

Affordable Price

You must know the price that you can pay easily for an effective solar heater. If you have an open budget, don’t just throw money on unreliable products. Read our reviews to find a cost-effective heater. If the company is offering a discount, check its motive as it should not sell you the poor quality.
