How Much Does It Cost to Run a Engine Block Heater in Nevada? (2026)
Block heaters keep an engine warm in cold climates so it starts easily. Plugging in all night is common but unnecessary; two to four hours before a start achieves the same result at a fraction of the cost.
A typical engine block heater (750 W) costs $0.098 per hour, or about $11.70 per month at 4 hours a day in Nevada. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (400 W) | $0.052 | $0.21 | $6.24 | $75.92 |
| Typical (750 W) | $0.098 | $0.39 | $11.70 | $142.35 |
| High (1,500 W) | $0.20 | $0.78 | $23.40 | $284.70 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 4 h/day ≈ 1,095 kWh per year.
One hour of an engine block heater (0.75 kWh) is the same electricity as
- 4.2km in an electric car
- 7.5hours of TV
- 17hours of a laptop
- 83hours of an LED bulb
In Nevada, with electricity at $0.13 per kWh (source: EIA Table 5.6.A, 2026-06), a typical engine block heater costs $0.098 per hour and about $142.35 per year at 4 hours a day. That is about 28% less than the national average for the US ($16.20 per month), because electricity in Nevada costs $0.13 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 10.3 hours of use.
How to lower the cost of running a engine block heater
- Use an outdoor timer set to switch on 3 hours before you leave.
