The Best Solar Pool Heater Buying Guide 2018

Introduction to the Best Solar Pool Heaters

Relaxing in a warm swimming pool during winter or late in the evening may seem like a privilege for the wealthy but it isn’t. There are fantastic pool heating options in the market giving everyone the opportunity to enjoy a warm and soothing swim. In this piece, we will be discussing the most affordable pool heaters in the market; the solar pool heaters.

Unlike their counterparts, solar pool heaters are the most affordable in both initial and running costs. On top of all this, they are the eco-friendliest of all the heaters in the market thus allowing you to enjoy a warm pool at night without damaging the environment.

Solar pool heaters usually use solar collector, pump, filter and the flow control valves to warm the water into your desired temperature. With this system, the water is pumped through the filters into the tubes of the solar collector. It is at this point where the water will be warmed up before it is released back into the pool. Some of the best solar pool heaters also feature sensors and diverter valves that are used to redirect water when the collector’s temperatures exceed the pool’s.

Another good thing about the solar collector is that it can also be used to cool warm water. This is a beneficial function especially to people living in areas of extremely hot climates or during the summer season.

Choosing the Perfect Solar Pool Heater

When shopping for a solar pool heater, you need to first look at the amount of sunlight within your house. What are the average temperatures within your surroundings? Knowing how much sunlight your area gets helps you in identifying the perfect solar heater for your pool. This is because even though all solar heaters use the same concept, they are customarily designed differently. Some are more suited to hot areas while others are ideal for places with minimal to diffused sunlight.

You should also know that solar pool heaters are designed to collect both diffuse and direct solar energy. It means that you don’t have to be living in an area with extreme sunlight to enjoy a solar heater. You should be able to use these heaters as long as you have an unshaded area within your compound where the solar heater can be installed to collect sunlight.

Knowing the amount of sunlight in your area will also inform you on the right side of the solar heater that you need to buy. While investigating the amount of sunlight around your house, you should also find a spot that receives proper amounts of sunlight for an extended period.

The next crucial factor is the size of the solar pool heater system. The size of the heater that you buy should be based on the temperatures in your area, your desired pool temperature and the size of your pool. The bigger the pool, the bigger the solar heater should be.  Likewise, the hotter you want your pool to be the bigger the solar heater you need. If your area doesn’t have too much direct sunlight and instead you have to rely on diffused sunlight, then you will also need a reasonably big heater. You can also use solar pool covers to reduce how big your panel should be, but this will cost you extra cash.

The size of your pool pump also influences how efficient a solar pool heater works. These heaters, typically require several or large pumps to boost water circulation for faster performance.

Finally, you have to look at the cost and ease of installation. In general, all solar pool heaters cost less to install than both gas and electric heaters but this price ranges depending on the specific heater you are using. While some are easy DIY units, others are more complicated and may even require the expertise of a professional to set up.
