The EnergyPlus boiler model is "simple" in the sense that it requires the user to supply the theoretical boiler efficiency. The combustion process is not considered in the model. The model is independent of the fuel type, which is input by the user for energy accounting purposes only.

Get A Quote11/6/2021 · Hi Nicole, it seems like there are two main problems: 1) Sizing is not as expected, and 2) Boiler consumption is too high. For 1), you might need to dig into the sizing routine for the low temperature radiant object. Here is a decent starting spot in the Engineering Reference.

Get A QuoteThe condensate is occasionally collected in a receiver and then pumped back to the boiler. EnergyPlus simulation mimics practical systems by assumed that the return pipeline is not insulated and accounts for this by calculating loop losses.
