It may be argued that not all of the heat gets into the food because some is lost into the kitchen. True. It also may be argued that an electric furnace has some loss of heat to the crawl space and that is true. However, your figure of 35 percent is much too low. If the ducts are well insulated a figure of 80 to 90 percent is much closer to the truth. As a matter of fact, every last watt hour of electric energy that comes into our homes is converted into heat. Believe it or not, I have run into faculty members in engineering who did not really believe that. The old engineering building was heated with resistance heat. This one guy kept going around turning off lights in the hallways even in the winter. I could not convince him that all of the energy that goes into lighting ultimately goes into heating the building and the thermostat will cut back, ever so slightly, on the main resistance heating. Lighting converts most of the electrical energy into heat and a little into light. But even the light gets converted into heat when it is absorbed by walls floors etc. The only exception is a very small amount of visible light that escapes through the windows. The power that goes into your stereo is mostly converted into heat. A small amount is converted into sound energy but when that is absorbed by the walls it is converted into heat. Only that small amount of sound you can hear outside has escaped the walls of your house. Even the escaping light and sound is ultimately converted into heat because that is the end point of all other forms of energy. Remember, energy can not be created or destroyed, it can only be converted from one kind to another. Back me up Dan? Regards. Max. K 4 O D S.
