Â*Â* What's your take on point of use heaters ? Ours is a small one ,
only about 1.5 gallons , mounted in the crawl space under the kitchen
sink area . The reason we got it was because hot water took too long
to get from the main heater (40 gal electric) to the dishwasher/sink
. Additionally , the main is set at 130° or so and we wanted minimum
140° at the dishwasher . Never got over 120° coming from the main to
the D/W and that ain't hot enough to sanitize the dishes .


I don't see much difference in cost wither way.Â* The small tanks are
often not as well insulated but if the distance to the regular tank is
long, it will save water as the hot will be there quickly.

As for the dishwasher, I get excellent results with 120 degree water
as there is a sani portion in the cycle that raises the temperature.
Coupled with the caustic detergent, they should be sanitized well.Â* It
also helps to use a good detergent.Â* We use Cascade Platinum and also
a rinse aid.

She buys the cheap stuff ... but we do use a rinse aid . I do like
having the very hot water at the sink too for those few items that we
hand wash . last rinse is straight hot .

I thought dish washers turned on the drying element to raise the
temperature of the water to a sanitizing level, no matter how cold it
was going in. I know there is a pretty good blast of steam coming out
if you shut it down right at the end of the wash cycle and open the
door. I don't have a dish washer here but there is always one in the
houses we rent on vacation.

I believe that is correct. I know on mine, it stops sometimes in at least
one of the cycels, pausing for a few minutes, which I presume is while
the water is being heated. They have the heater element down in the water,
it would be kind of stupid to not use it to heat water that isn't hot
enough. The exception there would be in the govt has some energy efficiency
standards they have to meet and if they let the thing run with cold water
they meet it, but heating it would not.
