Typical engine preheating wattages

• Midsize vehicle........600-1000 watts
• Large car or truck...1000-1500 watts

Use this formula to compute the cost to plug in your vehicle:
(Total watts / 1000) X hours used X 22¢ = Cost

Based on 600 to 1,500 watts, the cost range per hour to plug in is 13¢ to 33¢. That's $39 - $100 a month if you plug in overnight (10 hours).

A well-maintained vehicle only needs 2-4 hours of heating to start; 4-5 hours for diesels. Depending on your vehicle and heater type, that can be a significant savings - ranging from $24 to $75 a month.
