It was given off as waste heat, obviously.

I should have used the sarcasm smiley.

For some reason, it seems like this same question was already answered recently.

Have you forgotten what a chimney or vent is for? Do you want your house filling up with exhaust gas? Higher efficiency with a gas furnace involves making sure as little heat escapes in that process as possible.

What they said. Much of the heat is being wasted, either going up the chimney, or at least not being used effectively. Also the gas is probably not being burned completely, so a lot of the energy is also flowing up the chimney.

Furnaces get less efficient over time, due to various reasons. And old ones started less efficient than current models.

Interesting information about low-radiation effects on cancer incidence

I noticed someone mentioning light-bulbs in here. I used the old incandescent style, then I switched all my light-bulbs to the supposedly energy efficient bulbs... until one of them blew, it stunk to high heaven of burning rubber and the bulb was so hot you couldn't hold it, I have never felt a light-bulb that hot in my life. I done some research online and there have been several people reporting these things catching FIRE when they blow. There was a lady that had to pay our $3000 for cleanup when one blew due to it cracking and she had to hire people to do mercury cleanup (hazardous cleanup, whatever). Although newer versions no long have mercury that I know of, the fire hazard was enough for me, I switched back to the old style, and to be honest, my energy bill didn't change one penny even though I had the entire place changed over and back, in fact this month my electric bill was cheaper than expected so... I have to wonder how accurate the information is we get.

What worries me is they were talking about outlawing the older style bulbs (incandescent) in Ontario, which is nuts considering the fire hazard of the newer ones. Plus the fact that man made Global Warming is false anyhow and the worry over greenhouse gas is unwarranted... in my opinion anyhow.

I read plenty of reports online that say they're not a fire hazard, but I have also read reports that they HAD caught on fire, the people reporting they had aren't lieing, they merely reported their experiences and I know how hot mine got. I'm paranoid over fire so... I'll pass until forced to use them by law, at which time hopefully they would have improved them.

They do last a long time, but wait until one blows, and one WILL blow, you'll see what I mean. The stink is unreal, like strong burnt rubber, and so hot you'll literally burn your hands. Do some reading, they say that them getting REALLY hot that way is normal, and they can tolerate those high temperatures and the fire hazard thing is a myth, but there have been reports of them catching fire when they burn out, so it is NOT a myth, I've read the reports myself.

It wasn't a bad bulb, this is how they normally blow. Getting red hot isn't debated, this is a known thing from what I read. As for "energy savings", I debate that as well, I never saved one penny the several years I had my entire house changed over, now that I have all incandescent bulbs back in, I see no difference and my electric bill is still cheap as always. I honestly think the public's being lied to about these bulbs.

No, they all still do - and plenty of it (around 4 mg).

Based on the current electricty prices here (or at least last month's prices):

(60 watts) * (1 month) * (0.08 (Canadian dollars / kWh)) = 3.50632511 Canadian dollars

For a month of running a 60W incandescent bulb 24/7. So I guess its a bit more than 50 cents but I think thats what you end up spending on any given light if you only leave it on for a few hours total a day.

Nothing like a toxic mercury fire to brighten your day. We bought into the whole CFL bulb craze, but they're not worth it. The supposedly last years longer than incandescent bulbs, but the ones in the garage happily burnt out after only a couple years of infrequent use. Back to incandescent bulbs for me.

Except the fact that they'll not be still available down here. They already retired 100W and 75W and 60W ones.

August will mark the end of the 40W ones and December 2012 will mark the end of 25W ones.

All these production stops will lead us to have no more incandescent bulbs to sell at the end of 2012.
