Sizing to Heat Demand (Not Electricity)

The golden rule of CHP sizing is one sentence: size to the heat demand, not the electrical demand. Get this wrong and the most efficient technology becomes a money pit, because a unit sized for peak electricity produces surplus heat it has to dump. This lesson explains why heat leads, how to read the heat load-duration curve, where the base-load sweet spot sits, and how a thermal store buffers the mismatch.
