125 Volts x 15 Amps = 1875 watts.
So what's on the nameplate?

ever do the math? I did, they would have had to use 140 volts or close to it to even get even close to claiming the 1875 watts they claim:roll:

I have 8.333 ohms at 125 volts
15 amps, 1875 Watts
Did you even bother to read the link for the 8 year old thread? UL lists these things at 100% capacity of a 15 Amp circuit. They claim 1875 watts based on nominal supply voltage of 125.
FWIW, I have 125 Volts here at my place over 90% of the time.
The inefficiency of the motor as indicated by its higher current rating gets converted to heat also which is advantageous for the present case and the hair drier may thus outperform the space heater in heat production.That depends on the size and efficiency of the blower motors.
And it should always come out that way or close as with electric heating you are converting energy twice first heat to electric then back to heat, because of this there will be losses, of course hydro offers a lower cost solution but heat produce directly via a fuel will always produce more heat because of the single transfer theory, ever notice older electric dryers have a longer duration timer? I have seen some with a two hour timer on them, try this test, dry a load of heavy towels in a gas dryer then try it in an electric, see if it doesn't take longer in the electric, then there is the cost, here the cost is over 6 times between the two as our electric here is one of the highest in the US next to com-Ed.
Had a new customer who moved from Florida and had a house built and wired by someone else, they called me to find out why their utility cost was so high, well they made the mistake of having all electric heat installed 43.2kw of heating (3x14.4kw heating elements in 3 forced air furnaces), two large electric water heaters @5800 watts each, it was the first time I have ever seen a home require a 400 amp service around here as most only calculate out to be around 65 amps load with all gas appliances, their bill was over $1,000.00 a month, the electric appliances and heating was removed and all gas was installed, including a gas fired tank-less water heater and their bill is now is around $300.00 a month.
now in another area it can be different as if no NG is available propane can be costly in some areas, so the rule is do your home work, and for us who know which way is more expensive then we should advise our customers when we see a mistake like this about to be made, I do this all the time.

GSHP?
Ground Source Heat pump is way to go even if there is gas, but may have higher initial investment.
May have? I think you meant "is sure to be many times..." A friend just laid out $30E3 for his Levittown house with same. It makes sense in cases where:
In my friend's case, it was 2 that predominated.
- You have only Reddy Kilowatt or propane available for heat
- You have a high KWH rate and big summer AC loads
- both
