What is the function of a pool heater?

The function of a pool heater is primarily to raise the water temperature for swimmer comfort. This is crucial for enhancing the swimming experience, particularly in cooler weather or in areas where the water temperature might not be naturally warm enough for comfortable swimming.

By warming the water to a more pleasant temperature, pool heaters make it inviting for users, encouraging more frequent swimming, longer swim times, and overall enjoyment of the pool facilities. This function is especially valued in recreational settings, where comfort is a key aspect of user satisfaction.

While filtering or cleaning are important aspects of pool maintenance, those tasks fall under the purview of pool filters and maintenance equipment, not a heater. Furthermore, stirring the water and removing chlorine are not functions of a pool heater, making those options unrelated to its primary purpose.
