What Does It Cost to Run a Space Heater in Colorado?
This page estimates the energy-only cost to run a space heater in Colorado using a plug-in electric resistance space heater, an average load of 1,500 watts, and a typical runtime of 4 hours/day.
Key metrics
| Metric | Value |
|---|---|
| Average wattage assumption | 1,500 W |
| Typical usage assumption | 4 hours/day |
| Estimated monthly electricity use | 180.0 kWh |
| Estimated monthly cost | $30.22 |
| Estimated yearly cost | $367.70 |
Space Heater cost vs U.S. average
At the statewide average residential rate, running a space heater in Colorado costs less per month by $2.61 than the same usage pattern priced at the current U.S. average electricity rate.
How much electricity does a space heater use?
This estimate uses a typical wattage range of 750-1,500 W and a modeling assumption of 1,500 watts for 4 hours/day. Using the formula kWh = (watts × hours) / 1000, that works out to 6.00 kWh per day, 180.0 kWh per 30-day month, and 2190.0 kWh per year.
Most space heaters draw close to their rated wattage when actively heating, which makes them one of the more expensive household appliances to run. In Colorado, that energy is priced using the statewide residential average of 16.79 ¢/kWh, with a national benchmark of 18.24 ¢/kWh for comparison.
Space Heater operating cost estimate in Colorado
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 1.50 kWh | $0.25 |
| Per day | 6.00 kWh | $1.01 |
| Per month | 180.0 kWh | $30.22 |
| Per year | 2190.0 kWh | $367.70 |
These estimates isolate electricity usage only. Real utility bills can be higher because delivery charges, taxes, seasonal pricing, and fixed monthly fees are not included in this appliance model.
What changes the cost the most?
The biggest cost drivers for a space heater are the local electricity rate and real-world usage intensity. For this appliance, the main swing factors are thermostat cycling, room insulation, outdoor temperature.
If your usage is lighter or heavier than the assumption on this page, the linked state calculator and usage-cost pages below are the fastest way to model a custom scenario with the same state electricity rate.
