This setup uses about 29 kWh in a 30-day month.

01

Understanding Power Draw

The electricity usage of a outdoor heater depends on its wattage and how often it is used. We use the standard formula: (Wattage ÷ 1000) × Hours Used × Local Rate per kWh.

02

Tips for Energy Efficiency

To lower your electric bill, try reducing usage during peak hours or upgrading to a more energy-efficient model. Regular maintenance also ensures it runs efficiently.

03

Long-term Costs

Even small appliances can add up over a year. By unplugging devices when not in use, you can avoid phantom power draw and save money.

Rate source and limits

The default rate is the EIA U.S. residential average for April 2026, retrieved July 16, 2026. It is an average revenue per kilowatt-hour, not a quote for your utility plan. Fixed fees, taxes, tiers, and time-of-use prices can change the bill.
