Hot Water Generation

Solar energy can be used to provide hot water for domestic or industrial purposes. Low temperature water heating is an important contributor to lowering energy demand for heat in the residential, public and industrial sectors. In hot water storage systems for residential buildings, hot water must be heated to a minimum of 60° Celsius to prevent the growth of bacteria such as Legionella.

A tempering device ensures that hot water is delivered to taps at a maximum 50° Celsius. This temperature is considered sufficient for domestic hygiene purposes and effectively reduces the risk of scalding-related injuries from hot water use. Community kitchens, cafeteria’s in Hostels, swimming pools in residential complexes and hotels also require hot water.
