If your goal is to reduce your pool operation costs and be kinder to the planet, you might want to consider installing solar panels to help heat your pool.
Solar pool heaters allow water to be pumped through a filter and then through a solar collector, where it is heated. The heated water is then pushed back into the pool. The $3,000 to $4,000 investment can be great for those who are able to install solar panels in an unshaded area to collect direct solar energy.
As an added bonus, the solar collectors can also help cool the pool during the summer months.
