Inefficiency has only one place to go, and that's heat. It does so with
100% efficiency, owing to its being the only place to go.Lights work the same way, if you don't let the light out the window.
In 90 % of the US where KWH cost is double the cost per btu as NG you advocate leaving lights on , Stupid. Also T8 flouresent can output over 100 lumen per watt vs 17 for incandesant Thats right 6 times more efficent. 6 times more light. Incandesants are nothing more than heaters that put out light. 90 watt heat , for 10 watts light. Stupid for the cooling season, and stupid for 90 of the US where Elec is double the cost of gas. CFL output 40 - 60 lumen per watt , 4x better than incandesant You have no idea what energy savings are do you. I have 1800 sq ft . in winter my neighbor pays near 700 a month same size house . My costs went from 400 a month to 660 A YEAR with central air, from all energy star and flourescents. And no I leave crap on all day. Heat from motors, get real , Its negligable , KWH costs more, its not where you need it. Do some real research and learn. or look at your utility bills. You sound like a BSing lobbyist for the Utility Companys.
All the energy you put into motors comes out as heat. Every bit.
Furthermore it does it exactly as efficiently as an electric furnace. Same kwh gives the same heat.
All the energy you put into lights, incandenscent or flourescent, comes out as heat. It may be light first, but it hits the walls and gets absorbed (otherwise the room would keep getting brighter and brighter, wouldn't it!). It gets absorbed into what? Heat. All of it.
Execept what goes out a window.
It is all 100% efficient electric heating. Gas may be cheaper as heating, fine.
It's just that an efficient motor doesn't save as much as you think if it's running as part of a furnace. Whatever inefficiency it has contributes to heating at a 100% rate; as well as its efficient part! Motion winds up as heat too.
but is the excess motor heat sent into the house ducting? if not, then it's useless.
So you say its as efficent to use incansesants as T8 . In winter no not if you are like 90% of US with elec being double the cost of gas, also that " Heat ' may be up high or on a wall where you may not need it. Basement, outside, garage, etc. In summer Its stupidity. You pay to cool , so why heat with incandesants. Motor heat, Noise, Listen to your chimney , there is your noise energy, Gone. Why run a less efficent motor , especialy in cooling mode. You just pay more to cool. Take a house with flourescents vs incandesants, and a 94% Ac furnace vs DC Utilities will be lower with T8 and DC winter and summer . In theory what you say sounds sounds ok for winter for areas of low KWH cost that dont run AC and heat minimaly. But how many of us are in that locale. and how often will the perfect balance of light heat be optimal. Not often. Its most efficent to use efficent products
It can't pile up without getting hotter and hotter; so it has to leak away to somewhere where it can leave the house. The usual exits involve its heating the house first. It doesn't, after all, get hotter and hotter. It only gets hot enough so its leak rate equals its heat generation rate. If you insulate it, it just gets hotter until this equality applies again, and it's sending out heat at the rate it's generating it.
SO what,,, elec for most is Double the cost of Gas. And whats your argument when the AC is on ... Oh you dont have one, I thought so.
you're presupposing the heater is actually inside the insulated portion of the house. in my house, it's in a closet on an exterior wall, and the only door goes outside and isn't very well insulated (it needs air intake through the door).
therefore, the excess heat is heating the outside, not to my benefit.

Yeah, but if your furnace is only 50% efficient, it doesn't make any difference cost-wise between gas and electric heat.
