Keeping Water Heaters in Shape

Did you know that the efficient life of a water heater is about 10 to 12 years?  This of course can drastically shorten if you do not know how to properly take care of your water heater.  With the right type of preventive maintenance done periodically, it is even possible to extend its useful life.

Although, you must be aware that even if you extend it, there is a possibility that its efficient may have declined.  Here are useful tips you can use to maintain your water heater.

Physical Clearance

Draining the Tank

Regularly draining about a quarter of the contents of the tank will help remove debris and sediments that may have settled at the bottom.  This is a great way to prevent corrosion from forming.  To do this you need to turn off the supply and hook up a garden hose to the unit’s drain valve.

Drain the water into a bucket until it is clear.  Try to open the water supply valve of the unit to stir up whatever remaining sediment is left in the tank.  This also helps the water heater to operate silently.

This practice can also extend the life of the water heater.  Read through the recommendations of the manufacturer to ensure proper draining.  Caution should be taken when draining the tank because the water can be scalding.

Temperature Control

What is the benefit of setting it to the proper temperature?  For one, you can bring down your energy consumption by about 5% for every 10 degrees of reduction.  Second, you do not risk being burned by scalding water. And third, this helps to increase the life and efficiency of the water heating unit.

While you’re at it, take time to test the temperature-pressure relief valve.  Quickly discharge it about 2 to 3 times and check if there are any leaks coming from the valve after you test it.


Using an insulation jacket or blanket for your water heater will help limit heat loss to keep the water heated longer.  An insulation can save anywhere from 25% to 40% of your heating cost and lessens the stress on the water heating unit.  An insulation jacket or blanket can cost around $16.17 to $21.57 depending on the type and brand.

The insulation can also be done on the water pipes to further limit potential heat loss as the hot water travels to the faucet or shower.  Insulation can help older water heating units improve efficiency, although newer water heaters come equipped with insulation.  Both the hot and cold water pipes should be insulated.

Professional Inspection

Inspection of water heaters must be checked regularly by certified plumbing technicians.  This is important especially for the anode that should be replace every five years or so.  This practice will minimize the possibility of corrosion and will extend the life of the water heater.

Replacement should be done by a certified technician if about 6 inches or more of the core wire is exposed.  When the rod is about half an inch thick or coated with calcium, you should seriously consider replacing it as well.  Buying a 13-inch anode rod made of zinc-aluminum is a good choice.  This goes for about $16.

To get more out of your water heater and maintain its efficiency, use the proper setting when going on extended trips away from home.
