How Much Does Cyber Heater Cost to Run?

The simple formula

Running cost = heater power in kilowatts × hours used × your electricity rate. For example, a 500-watt heater (0.5 kW) used for 4 hours at 16¢ per kWh costs about 0.5 × 4 × $0.16 = $0.32. Use the calculator on this page with your own numbers.

Your rate is printed on your electric bill as cents or dollars per kWh. Rates differ a lot between states and provinces.

How zone heating can lower your bill

Heating a whole house to stay warm in one room wastes energy. Zone heating means turning the main thermostat down a little and using a small heater only in the room you're in. The U.S. Department of Energy notes that turning your thermostat back 7–10°F for 8 hours a day can save up to about 10% a year on heating.

Your actual savings depend on your home, climate, main heating type and habits, so we don't promise a specific number.

Tips to keep costs down

• Close the door of the room you're heating
• Use the timer so it switches off when you're asleep or out
• Set the thermostat to a comfortable, not maximum, temperature
• Block drafts under doors and around windows
