Swimming pool heating that is both efficient and ecological has become increasingly important to the development of new technologies and initiatives to protect the environment. This article, therefore, outlines previous research on the subject, acquired primarily from secondary sources and filtered based on criteria such as relevance, credibility, consistency, and applicability. Our goal is to provide an overview of the current literature and point out less-developed areas where research could be expanded. The results of the various studies suggest a widespread disagreement over calculating evaporation and make clear the need to generate integrative models that standardize this calculation.
