Technical Report
Application of a Linear Input/Output Model to Tankless Water Heaters
This study evaluates the applicability of a linear input/output model to gas-fired, tankless water heaters. The model can be used to reproduce performance metrics, such as the energy factor, and can be used to evaluate the impacts of alternative draw patterns and conditions.
