Which is why a gas stove has spark ignition and no always on pilot.

Many newer dryers do as well (spark ignition).

As for the furnace, it does get added, because it keeps the exchanger warmer (read pre-heated). Calories are calories. Just ask krw, (or fat boy Terrell). (oh, wait... his are different calories!)

He's "two tents!" Bwuahahahahahahahahah!

When I was a kid, our gas stove had a pilot flame per burner. Gas was cheap.

The gas pilot runs all the time, even when you need air conditioning!

Our furnace has a glowbar igniter/sensor. The electronics has only failed once so far.

Your gas must be falling back down the feed.

Oh, and aren't *you* "a flakey flame detector"? Just sayin'

I'm a triple-redundant flame detector: sight, sound, heat sensing. I know if a burner is on or off, but the stove electronics sometimes gets it wroong.

Your triple redundancy flame detector has a greatly reduced sensitivity on a nocturnal schedule and occasional short periods during the daytime. :-) Mikek

Maybe I don't understand your system- ours is forced air so any heat at all from the furnace would have to be taken away by the A/C heat exchanger in the summer.

Probably the best combo would be gas Hobbs and electric oven. We've got the IR flat-top electric ones which are okay, but not as fast as 'cooking with gas'.

They seem to have gotten it in the newer Weber grills. The electronic ignitor module is manually actuated, single AAA powered, sort-of sealed, and easily replaced for about $20 when it inevitably fails after a few years sitting out all winter.

The mechanical piezo BBQ lighters seem to be pretty good. No batteries, no electronics!

And likely smell. The methanethiol mercaptan odorant they add to NG is very effective. The standard requires 1/5 of the explosive limit to be detectable by a person with a normal sense of smell.

e pilot/thermopile system is bulletproof.

Things may be different in the US to here, and of course boilers do differ in design. But I can certainly say that no central heating boiler I've ever seen here captures the pilot flame's heat in any useful way. Its precisely why no new boiler has a pilot flame any more.

In old pilot lit boilers, the water pump doesn't run when the main burner i s out, so the pilot heats the exchanger, but that heat goes nowhere other t han up the chimney.

A friend has an LG refrigerator which seems to work ok, but it has a dashboard at the top of the opening that reduces the height for putting tall items on the top shelf. For what it does this seems rather wasteful. It could have been put on the side or even in the door much more effectively.

I've noticed the same poor design in other brands as well.

I was talking about Usenet, actually. ba-dum-ch (rimshot)

No, it keeps the water slightly warmer while the circulator is off. The burner will come on to keep the water warm, even if there has been no demand for heat. The pilot will add *slightly* (it is a small flame) to that heat, delaying the main burner *slightly*.

...and after a Winter outside, no work!

The sparker itself or the gas cartridge driven flame at the end of the stick?

Those piezo sparkers age and die from use, not from a simple chill.

...

There should be a circuit diagram somewhere---usually they stick it behind the air baffle at the front bottom. It usually pops out when yanked. Those things usually have an old-school wiring harness running around the box, even if it converges into a high-tech computer unit.

A day will come, of course, when they'll switch to ethernet (wired or wireless) bus linking all the sensors and actuators, and then we'll have to root the refrigerator to fix it :)

As already pointed out you're obviously describing a system wholly differen t to the ones we use here.

Yes, that's my experience too. Two or three tops.
