Interesting questions about heat. Yes, plasma sets generate more heat than LCD sets do. Some of the power is used to make light, some is used to make sound, some of it is given back to the power company from a "power factor" return due to the electronics / inductors, and the rest shows up as heat. My GUESTIMATE is that an LCD probably turns 1/2 of its consumer power into heat. Most of them are EnergyStar rated so they draw less than 100 watts. So thats about 50 watts of heat and 50 watts for the picture and sound.
Cnet's measurement for the 55GT50 after calibration showed about 250 watts power draw. If I use the same 50 watts for useable picture and sound, that leaves about 200 watts for heat. So lets put that on some kind of practical scale. A small plug in space heater maxes out at 1500 watts. It would take 7 or 8 55 inch plasma TV's to equal one small space heater. Light bulbs (old style) are very inefficient; they convert about 90% of the power into heat. So, a 55 inch GT50 makes less heat than 4 60 watt bulbs in the room. An "avearge" candle gives off about 70 watts of heat energy. So, 3 candles is close to one 55 inch GT50.
Bottom line, if 4 light bulbs or 3 candles would heat your room too much, then plasma is not for you. I estimate it would take about 146 GT50's to replace my furnace
