ENERGY MANAGEMENT IN AUTOMATIC DISHWASHING
The heating of water accounts for about
80% of the operating cost of a dishwashing. Here are some ways to help save on
energy costs:
- Operate dishwasher only when a full
load is accumulated. Avoid overloading. Overloading prevents
proper water circulation over the
dishes.
- Use the "rinse-hold" cycle or hand rinse soiled dishes while
accumulating a full load.
- Dishwashers use from 6 to 10 gallons
of hot water per load
depending on the cycle selected.
When dishes are lightly soiled, use a cycle requiring less water.
- Prerinsing dishes is not necessary. Simply scrape off food particles and
bones, and let the dishwasher do the
rest. Dishes and casseroles with
baked-on foods will probably need
pretreating, soaking or prescrubbing.
Gel automatic dishwasher
detergents may be used to pretreat
heavy baked-on foods on stainless
steel, glass, glass ceramic, porcelain,
enamel, and other dishwasher safe
items.
CAUTION: Avoid direct contact with skin
or clothing when using gel automatic
dishwasher detergent to pretreat dishes.
Wear rubber gloves. If detergent accidently comes in contact with skin, wash
immediately with water.
- Use the recommended amount of
automatic dishwasher detergent.
- The drying cycle on most dishwashers may account for about
15% of the total operating cost, so
skip it whenever possible. When
there is no "energy saving" air/no
heat cycle, simply advance the dial
after the final rinse to the "off" position. Use of a rinse agent
may help
promote drying.
- Keep the dishwasher in top operating condition, cleaning the filter
when necessary.
- If necessary, insulate water heater and delivery pipes to avoid
heat loss between the supply and
the dishwasher.
