      Moderate Climate (with 8’ ceiling and adequate insulation)
    • Square Footage x 10 = Watts required
    • Example: 100 Sq. Ft. x 10 = 1,000 Watts

    • Colder Climate (with 8’ ceiling and adequate insulation)
    • Square Footage x 15 = Watts required
    • Example: 100 Sq. Ft. x 15 = 1,500 Watts

    How To Figure BTU’s

    • Wattage x 3.413 (constant) = BTU’s (British Thermal Unit)
    • Example: 1,000 Watts x 3.413 = 3,413 BTU’s
    • Example: 4,000 Watts x 3.413 = 13,652 BTU’s
    • One BTU is the quantity of heat needed to raise one pound of water one degree Fahrenheit

    How To Figure Amperage

    • Watts/Voltage = Amperage
    • Example: 1,000 Watts / 120 Volts = 8.33 Amps

    How To Figure Voltage

    • Watts/Amperage = Voltage
    • Example: 1,000 Watts / 8.33 Amps = 120 Volts

    How To Figure Wattage

    • Voltage x Amperage = Watts
    • Example: 120 Volts x 8.33 Amps = 1,000 Watts
    • Example: 240 Volts x 4.16 Amps = 1,000 Watts
