RE: checking cfm for electric heat
Two problems with your formula. One is the delta and the next is the BTU/HR or in your case BTU. Both these values are used by the manufacturer and you have now idea what number they are using.
BTU/HR is determined by the allowable surface temperature as mentioned above. The delta T is based on recomendation by HVAC design guidelines.
