Fault Modeling Phase IV focuses on the faults in the plant loop, particularly on the fouling of water-based cooling and heating equipment. This is a continuous effort from current and previous FYs to build a list of common and impactful fault models to EnergyPlus toRead More
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.Read More
Boiler Sizing Generally boilers will need nominal heating capacity and rate. Both quantities can be straightforwardly obtained using the user specified loop sizing data and the loop design flow rates. All boilers on a loop are sized to meet the full loop load.Read More

Boilers: Engineering Reference — EnergyPlus 8.0 Boiler Load is a summation of sensible and latent heat addition to the water stream as Calculate the boiler supply steam mass flow rate at start of simulation. View More boiler efficiency guide - Cleaver-BrooksRead More
Steam traps are modeled in the EnergyPlus steam coil by assigning the condensate outlet from the coil a quality of 0.0 and sub cooling the condensate at lower pressure. Although condensate from the steam coil contains valuable heat, attempting to utilize this heat by holding the condensate in the coil reduces the heat transfer area.Read More
The coefficient values there give a very different curve for a condensing boiler, ie. Eff = 96% at 0.1 cartload and Twater = 50oC. My overall aim is just to model a non-domestic condensing boiler that is available in the UK but unfortunately have very little data on efficiency: Boiler efficiency Part load 30% at 50/30°C (gross) 97.4 %.Read More
