Custom Hot Water Load

This custom hot water load functionality has been built for experts with a firm understanding of sizing hot water systems, to enable advanced capabilities beyond the multifamily sizing available in the standard Ecosizer.

The load shape here should represent the peak hot water loads not the averages – designing to the average load can lead to a significantly undersized system.
