Solar Water Heating

Solar Advisor's Solar Water Heating model was developed at the National Renewable Energy Laboratory.

The current version of the model represents a two-tank glycol system with an auxiliary electric heater and storage tank for residential applications. The model allows you to vary the location, hot water load profiles, and characteristics of the collector, heat exchanger, and solar tanks.

Future version of the model will include additional solar system types and types of auxiliary systems and fuels. The current version's  built-in assumptions about collector arrays, piping, etc. are appropriate only for residential or small commercial applications. Future versions will allow for modeling of larger commercial and industrial applications.
