I never knew there would be a difference. I use hot water all the time and
never had a problem for many years.

1) the cold water helps cool the motor
2) Cold water in the grinder tends to throw particles down
the drain. Hot tends to throw sludge, which cools and
hardens later. Clogs the drain.

Water is used to cool the motor. Using hot water will shorten the life of the
motor. Always use cold water while the motor is running. After, hot water
can be used to flush out any grease, if that's your worry.

Cold water would help cool the motor.

But that begs the question of whether the motor needs cooling.

And even if it did, it's not a WATER-COOLED motor anyway.

I just ran my disposal for two minutes with NO water and the motor didn't
even get warm to the touch.

You took the words out of my fingers. I was thinking along the same lines
since the motor doesn't even near contact with the water.

I don't buy the water cooler theory. As I've stated, I always use hot water
and have never had a disposal go out.

The motor is air cooled, so irrelevent. Air cooled motors are much
cheaper than water cooled. Water cooling is only used where ther is
no air or the air is very hot. Even then, oil cooling is preferable
but even more expensive.
Submersible pumps and some circulating pumps are water cooled. Some of
then have the windings encapsulated in and oil filled can which is
water cooled.

The motor has a top bearing which would go bad faster with heat.

I use hot all the time to wash down any grease.

I don't see how water can cool the motor, as the water is not around
the parts
of the motor that get hot, ie the coils or armature. The grinding
mechanism
and water are well above that. You'd get some heat transfer down the
shaft,
etc. but doesn't seem like it would be that big of a deal. Also, I
don't know
how others use their disposal, but I use mine for a minute or two at a
time.
Hard to picture someone running it long enough with hot water, to
amount
to a heating issue with the motor.

I'd go more with the case that cold water tends to keep things like
fat solid
so they get ground up and sent down in bits, rather than liquid which
then
solidifies again in the pipes. Plus, how long does one
run the typical disposal? I run mine for a minute at a time. And
for me,
it doesn't much matter because
I'm not going to use hot water and pay to heat it when I can use
cold. On
the other hand, if the sink happend to have 3 inches of hot water in
it and
some vegetable debris, etc, I wouldn't wait for it to cool down
before
running it either.

Hot water will disolve the ground up grease, which will then congeal to the
pipes as it cools off further from the house, eventually plugging the pipes.

The disposals I've worked on had no sign of water cooling. No water got any
further than the end of the shaft beyond the bearing.

IF it's going to cool the motor any significant amount, it would have to. Maybe
it could cool the rotor a tiny bit, but it would have no effect on the outer
coils. Certainly not what is refered to as water cooling.

Waste King has the highest rated disposer on consumersearch.com, a

Did the manual say that the motor was cooled by the water, or are you just
guessing.

Did the manual, in fact, say, "always run cool water so the motor won't
overheat," or something similar.

Point is, my table saw motor will get hot, but the manual says nothing about
water - hot OR cold - having any bearing on the motor's temperature.

Your table saw is not designed to run with water flowing through it. I hope.

Okay, I'll play. How long does it take for the heat from a 60C motor to
transfer to the shaft such that the shaft is, oh, say 50C?

Thirty minutes? Ten minutes?

Then tabulate how long a disposal runs in a typical application.

Ten seconds? One minute?

I don't buy the water cooler theory. As I've stated, I always use hot water
and have never had a disposal go out.

I almost always use hot water and my disposers last years and years. I
think hot water keeps them from gumming up with grease.

Wrong, as usual. Water does cool the motor so it can be made
*cheaper*.

The disposals I've worked on had no sign of water cooling. No water
got any further than the end of the shaft beyond the bearing.

Why do you assume that it needs to?

IF it's going to cool the motor any significant amount, it would
have to. Maybe it could cool the rotor a tiny bit, but it would have
no effect on the outer coils. Certainly not what is refered to as
water cooling.

You really don't think there is a difference in 20C water on the
shaft and common surfaces and 60C water on those surfaces when the
motor is running? Moron.

There is a difference. But not a significant one. Moron.

Wow! Aren't you the swift one? Wrong, too.


Carbon steel ~ 90w/m C

That's per square meter one meter long. The shaft is perhaps .0004 m^2
and .1 m long * 40C

~14 W
