Question: Should Large Electric Boilers be calculated as a general load or a heating load?
With the wider adoption of electric boilers I am wondering what demand factors people are using to calculate large electric resistance boilers. I am not to familiar with the power usage patterns of these boilers, but does the 40% demand factor that NEC 220.82 (B) (3) allows to be applied accurately account for the demand factor of the boiler? Does calculating the boiler as a heating element make more sense?
