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.

Formula: Watts / 1000 x Hours x Days in Month = kWh

Example: 1500 / 1000 x 24 x 31 = 1116 kWh

The above example would equate to this engine block heater using 1,116 kWh in a 31-day period!
