Why do we say "hot water heater" when all we really need to say is "water heater"?

stupidity\nthis is one of the most ignorant terms a person can use\nalso 'close proximity'\never hear of something in far proximity\nbut you never know - maybe most of the people have hot water already coming into the house, and just need to make it hotter????

Some are photo electric...they turn light energy into electricity.\n\nSome are heat collectors...they store the heat and transfer it to the hot water heater.

Steel is the most common. Hot water heaters are steel tanks with a glass or 'stone' (Hydrastone (R)) lining to prevent corrosion. Cold water tanks may be made of heavy guage plastic. Underground cisterns are typically build of concrete blocks painted with a cement coat, or made of concrete.

In hotels the hot water circulates, at home you have to wait till the pipe from your water heater till your faucet is filled with hot water.

Any heating system works on a simple system:\n\n1. A heat source ('boiler') heats a circulating fluid;\n2. The fluid is pumped around the system heating other 'areas'\n3. The slightly cooler fluid is circulated back to the 'boiler' where it is reheated - by doing this we do not have to introduce additional fluid and it is more efficient to reheat already 'heated' fluid.\n\nHope this helps but if you need more drop me a note.

"Did you have a nice bath?" or "Did you have a nice shower?" "Did you enjoy your bath?" or "Did you enjoy your shower?" There's some options, that is if your tring to be nice. Telling them they smell better now probably isnt a good idea.

I'm sometimes scared of waterpipes, but only if I think about it too much.  But I am scared of those pipes that come off heaters that have all the insulation.  There's one in our attic that I have to step over every time I go up there, and it freaks me out.  The other thing I'm scared of are fire-sprinkers in my building, but thats just cause I'm afraid they'll go off and get my stuff wet.

Hi. Usually to minimize pressure variations in a home's water system. Fire extinguishers, aerosol cans, Coleman stoves, etc. all use them to store potential energy.

Exactly!! I have to boil water to take a bath. I do not have the luxury of a shower! I use gas for heat not central air and heat. I have to go out and turn on the water directly from underground so that I can fill it up in the tub. I also do dishes in the tub. I live in the United States doing this! I do not see myself as poor, but rich because my family is together and happy. I do not live like that and prefer not to because I like only having what I need to survive not a big house with lots of money. It is of no interest to me or concern. It is boring!! How is that for being against the normal American stereotype!! haahha!

The water in the tank is cold. This is condensation dripping down on the burner formed when hot air touches the cold tank. \n\nOnce the water is heated it never gets cold again so you should not hear it again.\n\nGet an "A"

THATS FALSE, ONE SHOULD FILL IT WHEN ONLY HOT. DUH.

Solar water heaters are a very effecient way to reduce the heating cost of your water supply and your home temperature if the correct system is installed. Sunnier states provide a better benefit than those with long winters and cloudy skies but they will still operate effectively enough to be beneficial.  The typical cost of a small system is recovered in 4-12 years depending on the purchase price and locale.

It's a verb. It's replacing "said" or "says."

It doesnt make a difference what a drink was before it is consumed. A drink is referred to as being hot or cold when its served to you. Thus you are literally drinking a cold or hot drink.

Not really sure about this one. It sounds like it originated in Britian but I can't find references to that. The US uses it  when discussing energy and the British uses it too but to a lesser degree. Sorry can't give a more fulfilling answer.\n\nCheck out.\n\nhttp://en.wikipedia.org/wiki/British_thermal_unit\n\nI did more checking and found this other site. Do I get the best answer award?!\n\nhttp://www.wisegeek.com/what-is-a-btu.htm

Great question!  It makes absolutely no sense!  Please rephrase it!  Using words actually found in English!  Thanks!

ignorance.  \n\nTo take it a step further though, I know many people who say they dont take the Lords name in vain, but they say; gosh, golly, jeez and things like that- those are still variations of the Lords names because those words derived from the words God, and Jesus.  \n\nI wrote an article about this at my website.  Click a link below if you are interested in reading it.  \n\nThe general idea, is that we need not interject words at all that are unnecessary.  Why say anything that isnt to the point anyways?\n\nWhy do we even add the space in a sentance for cursing?  Instead of saying things like "Jeez, its hot!"  Couldnt we just say, "its hot?"
