Tips on Choosing Solar Pool Heater

Solar pool heater is expensive, so make sure your purchase worth it. Here are some tips to choose solar pool heater that performs well for a long term:

1. Prepare enough space

An ideal area size for standard solar pool heater installment is around 75 percent of your pool size. It applies to pool that is open seasonally. If the pool is open all-year round, you need to increase it to 100 percent.

2. Consider roof shape and orientation

A solar pool heater depends on solar panels for the energy source. Consider the shape and orientation of your roof to make sure that the solar collectors get enough heat. If you live in the northern hemisphere, consider facing the collectors to the south.

3. Consider the geographical and climate factors

Aside from roof and solar collector orientations, you need to consider your surroundings. Mountains, hills, trees, or fog can hinder your solar heater’s ability to collect heat.

4. Understand the Btu formula and cost calculation

Btu is a measurement for a solar collector’s performance ability. To better manage your cost while using solar heater, you need to know the formula to calculate the amount of Btu spent for each Dollar. The easy formula is (Btu spent per day x amounts of solar panels): system installment costs.

For example, if your daily heater usage is 30,000 Btu, with three solar panels and US$4,000 installment cost, the amount of Btu you spend per Dollar is (30,000 x 3): 4,000 = 22.5 Btu per Dollar.

5. Choose reputable solar panel company installation

A reputable company is not just about proper installment, but also maintenance. The solar pool heater can last for 15-20 years, so it is best to choose installment company that will be around for many years.

Solar pool heater may be expensive and complicated to install, but it is a great option to save electricity bill and increase energy efficiency. The best thing is: you can do all of them while enjoying nice water temperament in the pool.
