Flat portion heating curve

WebMar 6, 2024 · The heating curve determines to what temperature the CH boiler is to heat the water at a given outdoor temperature. This relationship is described with the use of two parameters: the slope of the curve and its level. The prototype of the heating curve was the so-called ‘Stoker's table’, which helped determine the required supply temperature ... WebNote that most systems spend most of their lifetimes operating in this flat portion of the bathtub curve Finally, if units from the population remain in use long enough, the failure rate begins to increase as materials wear out and degradation failures occur at an ever increasing rate. This is the Wearout Failure Period.
