Water Heater Python Model

This project includes an electric water heater model in Python. This model is based on the EnergyPlus single node water heater model.

Table of Contents

Directory Layout

Currently a bit of a mess, the main model is "annual_ewh_run.py". Data files (draw profile, mains temp, and ambient temp" are in the "data files" folder.

Running the Model

To run the model, open and run "annual_ewh_run.py". Everything should run automatically and output results to "ElecWHOutput.csv"

This will apply the measures to the OpenStudio seed model specified in the .osw, run the EnergyPlus simulation, and produce output.

TODOs

  • Draw Profile - For mixed flows, iterate and use the current water heater temperature rather than last timestep's temperature
  • Validation - Get a better match on water heater consumed and delivered energy consumption to EnergyPlus (currently 10% difference)
  • Multinode model - Allow the model to work for n nodes (12 is pretty typical for a stratified tank). We'll also need to add master/slave element controls.
