Economic Aspects
The operation of electric resistance 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.
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.

Famous quotes containing the words economic and/or aspects:
“The chief reason warfare is still with us is neither a secret death-wish of the human species, nor an irrepressible instinct of aggression, nor, finally and more plausibly, the serious economic and social dangers inherent in disarmament, but the simple fact that no substitute for this final arbiter in international affairs has yet appeared on the political scene.”
—Hannah Arendt (1906–1975)
“An atheist may be simply one whose faith and love are concentrated on the impersonal aspects of God.”
—Simone Weil (1909–1943)
