Navisizer 3

NaviSizer is a tool specifically developed to facilitate the sizing of domestic hot water heating systems using Navien NPE Series tankless water heaters.

When used in residential settings, NaviSizer enables users to determine proper system sizing, calculate operational expenses and potential savings, and generates a detailed output suitable for project specifications.

When applied in commercial environments, NaviSizer incorporates ASHRAE Hunter Curve computations to size a wide variety of applications. It provides options for both tankless water heaters and tankless units with storage solutions. Additionally, it furnishes users with a detailed system specification that can be saved, printed, or shared via email.
