Watt
A measurement of electrical power. Rate at which one volt can push one ampere through an electrical circuit
One watt =.0569 BTU per minute
Approximate Percent Rated Watts When Reduced Voltage Is Applied:
120 Volt Heater On 115 Volt = 92%
120 Volt Heater On 110 Volt = 84%
120 Volt Heater On 105 Volt = 77%
240 Volt Heater On 220 Volt = 84%
240 Volt Heater On 208 Volt = 75%
240 Volt Heater On 120 Volt = 25%
480 Volt Heater On 440 Volt = 84%
| OHM'S LAW |
 |
| WATTS = AMPERAGE² x OHMS |
| WATTS = VOLTS x AMPERAGE |
