 coincident with boiler operation. You could calculate an EIR based on all fan power, controls etc. associated with your boilers. I haven’t plotted the default “Draft-Fan-EIR-fPLR” curve so you might take a look at it and make changes based on your particular

 the boilers are burning fuel.  The fan also has a hot water coil to keep the air at a minimum temperature to prevent thermal shock of the boilers.<o:p></o:p></p>
