Agure 4- 7 Water Use Before and After Retrofitting Apartment Buildings In the Washington.
D.C.. Area

Efficient hot-water systems. As was mentioned earlier, water heating is the second
leading home energy use. Although no reliable water-saving data are available, the following
guidelines can be followed to reduce hot-water use:
. Install low-flow shower heads and other water-efficient appliances that use hot
water.
. Insulate hot-water pipes. Insulation is accomplished with split foam tubing. It is
most easily installed at the time of home construction, but can also be retrofit on
exposed piping in a crawl space or basement.
. Turn down the water-heater thermostat. Most new dishwashers now preheat wash
water. If the house has one of these new models, set the thermostatto 1200F (50oC).
. Install a heat trap on the hot-water tank to prevent heat from escaping through the
hot-water line. This can be accomplished with a U-section of pipe.
. Place the hot-water heater near the center of the house to reduce hot-water piping
run.
