Electric Heat Method

CFM is calculated live from voltage, heat-only amp draw, phase, power factor, and measured temperature rise.

Power Phase *

Single Phase
Three Phase

CFM is calculated live from voltage, heat-only amp draw, phase, power factor, and measured temperature rise.

Voltage *

Electric Heat Amp Draw *

Altitude Correction Factor *

Default is 1.08

Supply Air Temp *

Return Air Temp *

Calculated Temp Rise

Auto-calculated as Supply Air Temp minus Return Air Temp.

Calculated Electric Heat CFM – Single Phase

Auto-calculated live. VOLTS X AMPS X 3.41 / 1.08 / Elec heat temperature split = CFM

Calculated Electric Heat CFM – Three Phase

Auto-calculated live. VOLTS X AMPS X 1.73 X 3.41 / 1.08 / Elec heat temperature split = CFM

Electric Heat Photos *

Drag & Drop Files, Choose Files to Upload You can upload up to 6 files.

Upload heater data plate, voltage/amp readings, and temperature readings.

Gas Heat Temperature Rise / Clocking Meter

Enter gas heat readings. CFM is calculated live when output BTU and temperature rise are entered.
