High Volume Hot Water Uses

High volume hot water applications can be accommodated with the SIO 18 Pro or Pro Flex by installing the units in a parallel configuration. The units operate independently from each other and are connected to the cold water feed lines individually with the hot water drop lines feeding a common hot water supply line or resupplying hot water to a large storage tank. 


These installations can supply hot water to large residential structures with 4+ bathrooms with multiple shower heads or whirlpool tubs as well as commercial applications such as restaurants, hotels and other large volume hot water applications. 


The following images show each type of installation.
