I keep reading ads for used cars saying "new breaks" instead of brakes. I don't want to buy a newly broken car.
Ok , back to the hot water heater thing. Technically , two fingers is correct. There can really be no such thing as a "hot water heater. If the water's hot , it doesn't need to be heated again. If the water's cold , then it needs to be heated , however, often on blueprints for houses , the area where the water heater will be placed is designated with a circle with HWH written inside of it. I remember the water heater vs. hot water heater thing being discussed at great lengths in plumbing class. Because of the HWH use on blueprints , it was determined that "hot water heater" is an incorrect term , but acceptable.
WSSC Plumbing codes and enforcement class , level 4. 1974

Edit: I will add that if anyone in the class used the term "hot water heater" , they were quickly and soundly corrected by the class instructor.

...but hot water heaters regularly heat hot water - insulation not being 100% efficient guarantees it.

As this was explained in the class , "The purpose of the device is to heat (raise the temperature)the water. The starting ambient temperature of the water within the device is irrelevant to the process. By your definition , if you drain the water heater and start with all cold water in it , it becomes a cold water heater and again , the ambient starting temperature is irrelevant. It is neither (or both) a cold water heater or a hot water heater but if you called it either in the codes and enforcement class , Mr. Jennings would swiftly and soundly correct you. Only one student made that mistake and the response has stayed with me all these years.:wideyed:
The HWH designation on blueprints is to avoid confusion between a water hydrant , also called a hose bibb and a water heater.

...and now you know why I became an Electrical Engineer instead of an electrician, because then I got to be the arbiter of pointless details and correct folks for it.

Of course now I'm both a technician and the engineer - so whenever something is stupidly designed, or impossible to repair... I have to blame the designer, who happens to be me.

Problem is - in those days most folks were the latter.

In 1700 male literacy rates in England, one of the more literate countries in the world at the time, were under 60%.

In 1700 female literacy rates in England were well under 20%.

1700 you say. Not at all relevant to the last the reality of 2015. You know UNIVERSAL EDUCATION in the first world.

You (or someone else) not I, used the term golden age. I get that you immediately think of the golden age of literature and what you say is true.

I speak of the golden age of LITERACY as in UNIVERSAL EDUCATION in the first world. That's what, the last 60 -70 years?

You still refuse to acknowlege the fact that people would rather write paragraphs defending that it doesn't matter when they could, in the same amount of time, learn how to say a word correctly.
