condensing boiler efficiency curve

condensing boiler efficiency curve

  • Figure 1 depicts a typical efficiency curve for a condensing boiler relative to return-water temperature. Two main points can be gleaned from Figure 1. First, operating a boiler with a return-water temperature above 140 F yields a peak thermal efficiency of roughly 88 percent. That means it basically is performing like a non- condensing boiler.

  • Has anyone come across issues with the default condensing boiler curve in eQuest? This curve is a function of part load and return water temperature, and based on how condensing boilers work you would anticipate the part load efficiency to get worse as return water temperature increased (assuming part load is the same).

  • For the past few decades, an increasingly popular space heating option is a system with a modulating condensing (mod-con) boiler. Because these boilers can potentially have a high efficiency (90-95% or higher), they are often promoted by state and utility subsidy programs.

  • Apologies for what is almost certainly a very dumb question but I'm struggling to understand what the boiler efficiency curves in the EP example files actually represent. Looking at InputOutput reference for the formula and plotting the biquadratic condensing boiler efficiency curve data given in the boilers.idf file gives Eff = 112% at 0.1 part load and Twater = 50oC for example.

  • Please note that the boilers.idf document you linked to clearly states: "For the curve below, specify EnteringBoiler for the Efficiency Curve Temperature Evaluation Variable". According to that, the second independent variable is return water temp, not supply water temp, for this boiler performance curve.
