AS a retired electrical engineer I enjoy the electrical discussions on here now n then n try to help with questions the best I can. Also, as an engineer YES I KNOW A WATT IS A WATT...... regardless if its consumed and converted to various other energy forms like say an electric motor (magnetic field and rotation) or light bulbs (light n heat) or a cheap wal mart electric heater (heat maybe a lil light) or an expensive Amish built or Eden pure heater (heat maybe a lil light) etc etc.......
BUTTTTTTTT MY QUESTIONS FOR FUN DISCUSSION ARE:
The reason is Im sure we would all agree (engineers n technicians n laymen alike)
1) If we consumed 1500 watts in a room by running a 2hp or so electric motor, since some of the energy goes to magnetic field and some to ROTATION, there would probably be less heat generated then if we ran a 1500 watt electric heater EVERYONE AGREE??????
2) Although EITHER would consume 1500 watts, if we burned 1500 watts worth of the higher efficient (more lumens/watt) CFL bulbs we would get more light (lumens) then if we burned 15 100 watt incansescent light bulbs EVERYONE AGREE????
3) SOOOOOOO just as CFL lighting is more efficient then incandescent (more lumens per watt),,,,,,,,,, and just as A 3 phase motor is more efficient then a single phase motor ,,,,,,, AND SURE A WATT IS A WATT AND EITHER OF THE ABOVE CONSUMES WATTS BUT DOES NOTTTTTTTTTTTTTTT YIELD THE SAME IN HEAT OR LIGHT, Id think a more efficient electric heater (more BTU's per watt) will yield more BTU's per watt then a less efficient electric heater..
Everyone agree??????????
4) Or do some think any electric heater (strip or quartz or infrared, Wal Mart or Eden Pure or Amish etc etc etc) ALLLLLLLLLLLLLLLLL have the same BTU per watt effiency????????????????
5) Does anyone have any hard data regarding the EFFICIENCY in BTU's per Watt of say wire strip heaters versus infrared versus quartz etc etc
CLOSING:
I think Question 5 is the key here so we need the actual hard data OF THE BTU'S OF HEAT GENERATED VERSUS WATTS CONSUMED for strip or quartz or infrared heaters etc etc UNLESS someone has data that ANY TYPE OF ELECTRIC HEATER yields the same amount of BTU per watt !!!!!!!!!
A THOUGHT: The inefficiency of a motor or light etc is that some of the energy is "wasted" in the form of heat losses versus light or rotation soooooooooooo if the inefficiency of an electric heater is due to some of the energy is wasted as HEAT welllllllllllllllllll there ya go anyyyyyyyy heater is the same ??? Hmmmmmm lol
Sorry so long, as an engineer now an attorney I cant help myself lol
God Bless yall n keep warm now ya hear REGARDLESS how efficient you do it
