(21 amps on each leg) 440, three phase heater,
21 * 440 * 1.73 = 15985 watts . is this correct? There is no power factor on pure resistance loads, right? thanks

No, your ANSWER TOTAL is not correct. PF=1 on a purely resistive load. Once you get the right answer try to find the resistance on the load post back with the resistance total. Have fun!
