Spend Less to Operate Your Water Heater.

By Fisher Swanson

Your water heater accounts for between 14% to 20% of your
household energy expense. In this article, I am going to
show you some ways that you can cut down on the amount of
energy you use in heating water.

Water Heater Settings, Insulation and Maintenance.

Set your water heater temperature to 120 degrees. That
should provide a warm temperature for bathing. If you have a
dishwasher, check the specifications for the minimum
temperature that it requires. If you have an electric hot
water heater, look into installing a timer that turns the
heater off when you are sleeping or not likely to use water.

Insulate your storage tank and pipes. You can purchase
insulation kits at your local hardware store. Avoid covering
the thermostat. It's important to insulate your heater
correctly. If you are not sure what to do or can't find a
good "how to" guide, you should have a professional install
it.

Clean the sediment out of your water heater. This can be
done by draining a quart of water from the water tank once a
month. The sediment impedes heat transfer and lowers the
efficiency of your heater.

Hot Water Usage.

Install aerators in faucets and low-flow showerheads.
Aerators deliver a strong spray, but control your water
consumption by mixing air with the water.

Repair leaky faucets quickly. It's amazing how much water
you can waste in a short period of time when you have a
leaky faucet.

Take showers instead of baths. On average, a 5 minute shower
uses half as much energy as taking a bath. A longer shower
might use as much water as bathing, so use your judgement on
what method is best for you.

The good news is using a dishwasher tends to be the most
efficient way to wash your dishes. Be sure to run full loads
and use energy saving settings if your dishwasher has them.
If you have an old dishwasher you might consider upgrading.
You can get a new, efficient dishwasher that uses 5 gallons
or less per load while an older dishwasher could use twice
that amount. There have been a lot of advancements in
dishwasher capacity and efficiency; a new dishwasher uses
half the water and electricity than one sold in from the
early 1970's. If you wash dishes by hand, keep in mind that
a running faucet uses 2.5 gallons of water per minute so try
not to leave the water running as you wash.

Purchasing a Water Heater.

If you are in the market for a water heater you are going to
want to buy a gas-fired heater if natural gas is available.
It's more efficient than an electric water heater. If you
don't have gas in your area, but live in a warm climate, you
may want to look into solar water heaters.

The most efficient water heaters available are Demand
(Tankless or Instantaneous) Water Heaters. Demand Water
Heaters have been used in Japan and Europe for decades. They
have been available in the US; but until recently, have not
been very common. Demand Water heaters use less energy
because they heat the water as you use it instead of keeping
a tank full of water warm 24 hours a day. They are more
expensive to purchase but last 25% to 30% longer.

Buy the water heater that fits your household's needs. If
you are buying a used water heater, be sure to research how
much energy it uses. If you are buying new, read the labels
and buy one that is going to cost less to operate. Keep in
mind that you are going to use the water heater for 7 to 15
years; spending a little more initially can save you money
in the long run.

I hope you will find some of this advice helpful. We rely on
our water heaters and tend to forget about how hard they
work for us. Take time to properly maintain yours and you
will be rewarded when you get your energy bill.
