What Makes a Good Solar Heater

Brands are too many and the models are too plenty. That being said, buying a solar pool heater for your home is a quite complicated affair. If you are confused about the things to consider before buying a solar pool heater, check them out below.

Number of Panels Relates to Pool’s Size

The number of panels is probably the first thing you must take into consideration when buying a solar pool heater. The measure of energy a solar heater can derive from the sun is often determined by the number of panels the heater has or the wideness of the panels. While the bigger the better is always the case when it comes to solar panels, ensure you have the required space available.

Temperature Increase Is King

Probably the most important factor you must check before buying a solar pool heater is the temperature. Needless to say, that’s the reason you are buying the heater in the first place. A normal solar heater will raise the temperature of your pool by 5 to 10 degrees. However, there are some high-end models that can raise the temperature of your pool by 15 degrees.

Consider Size and Weight

The size and weight is also a complicated factor you need to consider. Like we mentioned above, solar heaters consume space according to how powerful they are. Unfortunately, you would have to make a compromise on space here. So, do you have a large pool which requires a very powerful solar heater? Make sure you have space.

Don’t Forget About Warranty

Solar pool heaters are costly products, so you can’t afford to be replacing them often. Therefore, you must check if the model you are looking at comes with a warranty. It is even believed that a manufacturer’s confidence in his product is often depicted by the warranty.

Installation [Can You Do It Yourself?]

How easy is it to install the solar pool heater you are looking to buy? This is another factor you must consider. If you are not ready to pay a professional to do the installation for you, then you should definitely find a solar heater that is easy to install. Also, you should check if it comes with the required installation gear so you wouldn’t have to buy any accessories.
