In hotels, hospitals, swimming pools, and sports centers, hot water is a constant need, and meeting this demand typically involves high gas consumption. This Intersolar Mexico webinar will show you how solar thermal energy can efficiently meet that demand, reducing operational costs and carbon emissions. An expert in the installation of solar water heating systems in Mexico will share success stories, benefits, and key recommendations for implementing this technology in the commercial sector.
The recording and the speakers' presentations are available here .
