Webinar: IECC Energy Codes and Hot Water Distribution: The Benefits of Demand Controlled Recirculation Systems

For many newly built homes, the hot water delivery times at some fixtures are substantially longer than from homes built in the past, resulting in wasted water, energy, and frustrated occupants. Recirculation pumps can be incorporated into a hot water system to significantly reduce the time to tap and therefore achieve water savings. Too often though these pumps are left running excessively, which then causes the water heater to run longer to make up for distribution heat losses. The IECC now requires demand sensing controls for service water heating circulation pumps to regulate the runtime of the pump and help mitigate energy losses while preserving the usefulness of the pump. This session will cover the basics of on-demand hot water recirculation technology and the impact it has on building performance relative to other methods of hot water delivery.
