Engine Block Heater Consumption Calculator.

Have you ever wondered how much power your

block heater really uses (i.e. plugging in your vehicle or

tractor)? An average block heater can use up to 1500

watts. By using this simple formula, you can calculate the

approximate consumption of your block heater.

Watts / 1000 x Hours x Days in Month = kWh

1500 / 1000 x 24 x 31 = 1116 kWh

This would equate to this block heater using approximately $133.81 of Energy in a 31-day period.
