Enter the total heat input and the system efficiency (%) into the Heat Output Calculator. The calculator will evaluate the Heat Output. 

Heat Output Formula

The following two example problems outline the steps and information needed to calculate the Heat Output.

HO = HI * E/100

Variables:

  • HO is the Heat Output ( )
  • HI is the total heat input 
  • E is the system efficiency (%) 

How to Calculate Heat Output?

The following steps outline how to calculate the Heat Output.

  1. First, determine the total heat input. 
  2. Next, determine the system efficiency (%). 
  3. Next, gather the formula from above = HO = HI * E/100.
  4. Finally, calculate the Heat Output.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total heat input = 40

system efficiency (%) = 25

HO = HI * E/100 = ?
