On older boilers (furnaces if you're American), when the heating isn't actually running (eg. the thermostat says the house is warm enough), there's no power to the boiler, so how does the pilot light valve stay open with the tiny voltage (40mV?) and current from the thermocouple?


The basic problem with english engineering is that it hasn't advanced much beyond the 1500s. We superior Americans, however, employ the use of electronic ignitors.

As do we with new boilers. But our stuff must last longer because a lot of folk still have one with a pilot light, the only ones that don't are the morons that thought they should spend £1000 to get a boiler that will save them £50 a year on gas. So you make a profit in 20 years time, why bother? My boiler is at least 25 years old and I've only ever replaced the thermocouple for £7. It could be newer fancier boilers have more to go wrong, I've heard of a modern boiler lasting only 7 years!!

If you don't know what that is, see one of my recent poasts concerning the pigtailing of neutral and ground circuits.

What has pigtailing to do with electronic igniters?

You'd need an electrician's license to even comprehend what I would tell you about that.

Licenses are for pussies. I just prefer to get on with the job.

IF I ever hire anyone (and usually I do all my own work), I purposefully avoid anyone with any certifications, it just means they charge more and are more fussy and won't do the work the way I want it.

Colon Burke is the idiot who said the top pin of a 3-pin plug was for
neutral.

Technically it is. Earth = neutral = 0 volts.

That's what that idiot KKKoloon thought. Neutral is not the same as
Earth (aka Ground in the Great Satan).


Zero is zero. If I connect my desk lamp to live and earth, it will function the same.


Do you actually do that, though? If not, why not?


I have done in the past, I've used an earth to power a PIR lightswitch for example as it previously had no neutral there for a simple manual switch.

I also disconnected the chassis earth on my microwave, as my pet parrot likes to sit on it when I'm not looking and might one day chew the cord. 240V in the beak, 0V on the feet, bad idea.
