Converting older non-condensing boilers to high-efficiency condensing boilers has been a popular Energy Conservation Measure (ECM) for a number of years, but the measurement and verification of this ECM has lagged behind. Option A (retrofit isolation with key parameter measurement) is typically selected for boiler replacement ECMs with the key parameter of combustion efficiency. However, current industry standard methodology relies on difficult combustion testing requirements in order to account for the latent energy that is partially recovered from flue gas by condensing boilers. This presentation will focus on current methods used to measure condensate/latent energy recovery and new calculation methods used to simplify the process. The objective of this presentation is to highlight potential challenges surrounding combustion efficiency testing for condensing boilers and to assist in developing a successful Measurement and Verification Plan to quantify energy savings for boiler replacement measures. Professionals involved in day-to-day measurement and verification activities are targeted for this presentation.
