Applies when electric input and useful work both become heat within the considered space.

Units

q_{\text{equipment}} = 3412 \times \text{Input}_{\text{kW}} \times \text{Use}_{\text{factor}}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.
