To determine the number of amps typically used for each 5 kW of heat produced, we can apply the electrical power formula, which states that power (in watts) is equal to voltage (in volts) multiplied by current (in amps).

For heating systems, especially in the context of electric heat, it is common to use a standard voltage of either 240 volts or 480 volts. Assuming a common residential voltage of 240 volts for electric heating applications:

  1. The total power in watts can be converted to kilowatts (kW) to understand it in a familiar unit. So for 5 kW, we have:
  • 5 kW = 5000 Watts.
  1. Using the formula:

[

Power (W) = Voltage (V) \times Current (A)

]

Rearranging this gives:

[

Current (A) = \frac{Power (W)}{Voltage (V)}

]

  1. Substituting in the power and the standard voltage:

[

Current (A) = \frac{5000 W}{240 V}

]

  1. Calculating this:
