In this video, Bill Bailey, discusses how to right-size replacement boilers.
With three primary methods available for determining the output requirements of a new boiler, Bailey emphasizes the importance of accuracy to avoid oversizing, which can lead to unnecessary costs and inefficiencies.
The first method discussed is the load calculation approach, which involves conducting a thorough heat loss analysis of the building. Although accurate, this approach can be problematic if data is outdated or inaccurate.
The second method, known as the tag method, involves inspecting the existing boiler's specifications. While this provides a starting point, facility managers shouldn't assume that the boiler's output aligns perfectly with the building's needs, as oversizing is prevalent.
The third method, and preferred by Bailey, is the Equivalent Direct Radiation (EDR) calculation, which offers a more precise and tailored approach. EDR involves assessing each radiator's heat output capacity based on its size and design.
