But, instead, we have a world population increase.

If 1000 people in the same city, dropped dead from smoking on the same day. Then they would have an investigation.
I'll agree with that in a heart beat.

If you added up all the reports that attributed death to certain causes

you'd exceed the national death rate by afactor of twenty.

Just Google "Death Rates", add up all the totals and compare the sum to federal stats. It'll blow your mind how out of proportion the two are to one another.

Robertshaw had to recall a bunch of defective gas valves for water heaters back in 2003 .. old stuff has safety advisories published all the time.

While I agree 40 years is a reasonable lifetime for a part, parts in a critical safety system should always "fail-safe", not "fail-deadly". The rationalle behind a recall or advisory is based on how many systems are believed to be in service, and it's the government's job to at least warn people that "hey .. if you've got one of these dinosaurs .. ya might consider replacing the gas valve, since they seem to be going bad in a very bad way".

As for the "40 year old" and "efficiency' issue .. this unit is 80% based on nameplate input/output .. just like the lower-end ones they still sell. Sure, I could install a 95%+ one, but that 15% is a long payback. We'll probably replace it anyway next year before the tax credit expires, but because it's in the middle of the house, that involves running new pipes through the roof for combustion inlet and exhaust air (and re-flashing the roof, etc.) .. plus I need to buy a sheet metal brake and learn how to use it (and how to braze lines for R422a .. I understand that needs an expensive 2-headed torch).

I also need to replace the unit in my house, so spending $1000s on tools is better than paying some contractor thousands to come out and screw both of us over. I actually took the EPA test for refrigerant recovery on-line so I could buy Freon to fix my cars and home unit from time-to-time. The gauges and tank cost way more than it would for a service call, but like the old addage says "teach a man to fish, he eats forever".

Furnace gas valve


Your bonnet/steady state efficiency may be 80%.
But your AFUE is only about 60%.


Nope, doesn't take a 2 headed tourch.

Is your EPA cert, for Section 609, or 608.
Need 608 for stationary equipment.

Don't forget to buy a pittsburg machine also.

Whoa..right between the eyes on the input and out put ratings.


Mindcandy , no disrespect, but I would stick to what your good at. Furnace design is not it. Aside from what Beenthere posted there are a myriad amount of things that make your GE a gas hog. You have air going up the flue on the off cycle. You have jacket losses. Your blower is not efficient enough to meet current efficiency standards.

And on and on....
