Thermal load is demand for heat energy. The heat may be needed for space heating, hot water heating, or some industrial process. The thermal load can be served by the boiler, by a generator from which waste heat can be recovered, or by surplus electricity. If you want a generator to serve the thermal load with waste heat, you must specify a non-zero value for that generator's heat recovery ratio. If you want surplus electricity to serve the thermal load, you must add a thermal load controller.
Click the Thermal Load under the CHP section. This should open up the thermal load set up page:
You can specify a thermal load by choosing one of the three options:
•Creating a synthetic load from a profile.
•Importing a load from a time series file.
•Download thermal loads from OpenEI database
