FLOW CHART AND HERS DATA
The Home Energy Rating System (HERS) Index is the industry standard by which a home’s energy eciency is
measured. A lower HERS Index Score means a more energy ecient home, which means lower energy costs.
Data analysis conducted by independent third party HERS rater compares traditional electric and gas residential storage tank water heaters
to Rinnai’s Condensing and Non- Condensing Tankless Water Heaters. Consult and validate your specic application with a local HERS rater.

Tankless water heater output is based on delta T which is the dierence between the incoming water temperature
and the requested output temperature. This chart is used along with other factors to help size the Rinnai Tankless
model for your application.
