Enter the system voltage (volts) and the system power (amps) into the Heat Strip Size Calculator. The calculator will evaluate the Heat Strip Size. 

Heat Strip Size Formula

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

HSS = V * A / 1000* 3413


  • HSS is the Heat Strip Size (BTU)
  • V is the system voltage (volts) 
  • A is the system power (amps) 

To calculate the heat strip size, multiply the voltage by the power, divide by 1000, then multiply by 3413 to convert into BTUs.

How to Calculate Heat Strip Size?

The following steps outline how to calculate the Heat Strip Size.

  1. First, determine the system voltage (volts). 
  2. Next, determine the system power (amps). 
  3. Next, gather the formula from above = HSS = V * A / 100 0* 3413.
  4. Finally, calculate the Heat Strip Size.
  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.

system voltage (volts) = 10

system power (amps) = 40

HSS = V * A / 100 0* 3413 = ?
