The operation of electric heaters to heat an area for a long period of time is generally considered to be costly. However, intermittent or partial day use can be more cost efficient than whole building heating due to superior zonal control. Your Space Heater Example: A lunch room in an office setting has limited hours of operation. During low use periods a "monitor" level of heat (50 °F/10 °C) is provided by the central heating system. Peak use times between the hours of 11:00–14:00 are heated to "comfort levels" (70 °F/21 °C). Significant savings can be realized in overall energy consumption since infrared radiation losses through thermal radiation are not as large with a smaller temperature gradient both between this space and unheated outside air as well as between the refrigerator and the (now cooler) lunch room. Economically, electric heat can be compared to other sources of home heating by multiplying the cost per kilowatt hour by the number of kilowatts the heater uses.
