Both electric and gas pool heaters take the chill off a winter dip in the pool But who wants to add that expense to their money? Solar pool heaters operate on the same principal as a domestic water heater. “Therms” are absorbed by a collector and transferred to the water. The water is circulated by the filtration pump and diverted to the thermal collector.
No additional energy is required, since the pump is scheduled to run anyway.
Conventional pool heating units are both expensive to purchase AND expensive to operate. Solar pool heaters are composed of inexpensive thermal collectors and require a minimum of additional PVC plumbing AND cost nothing extra to operate. These systems can easily be installed in a day.
