The quickest way to reduce your water-heating expenses is by adjusting your habits. Some of these tips can make a surprising difference in consumption without causing much hardship.
You can also make some inexpensive improvements to your water heating system that will produce a handsome payback. Taken together with the above changes in habits, these improvements can help most households save a third or more of their water heating bills.
One of the most effective ways to reduce water heating bills is to reduce the temperature of water in your storage tank. That's because many storage water heaters are set to keep water at 140 degrees F. or more, causing more heat to conduct through the walls of the tank than would occur at lower temperatures. High water temperatures also encourage scale and corrosion to form inside the tank, shortening the life of the tank.
If you can keep it below 120 degrees F, the savings abound and you use less cold water mixture to get a usable temperature at the faucet.
Showering is typically the biggest hot water use in the house, and so should be one of the first places you turn to reduce your consumption.
Modern low-flow shower heads must by law deliver less than 2.5 gallons per minute (GPM). Most can do this while still producing a satisfactory shower - a design advance that includes controlling the size of the droplets and mixing air into the water. In California, these as well as water saving toilet tanks must be installed when a home sells. Both buyer and seller need to sign off on it before escrow closes.
