Water Heater Life Expectancy
By Sid Baysinger
TRADITIONAL TANK WATER HEATER
Installing and repairing water heaters for almost 40 years has taught me much.
The average water heater life expectancy has diminished over the last 30-years.
Thirty years ago you could expect a new water heater to last at least 20-years or more, even without regular maintenance.
HOW LONG WILL A NEW WATER HEATER LAST IF PURCHASE TODAY
Tank failure (leaking) is the only reason to trash a unit, everything else can be repaired.
A tank with a six (6) year warranty (most common) should last 10-12 years, with some preventive maintenance.
You can purchase fiberglass or stainless steel tank type water heaters with life time warranties, however the cost is very high. Upgrading to a gas tankless is a much better choice if you have an existing tank type (traditional) gas water heater, plus you will save up to 40% on your gas bill and most tankless can last up to 25-30 years.
WHY DOES A TANK WATER HEATER FAIL AND LEAK
Hard water mineral sediment collects at the bottom of the tank, this separation of caustic minerals is caused by hot water temperatures exceeding 120 degrees and greater, the minerals form layers at the bottom of the tank in the form of a jelly, after about 18 months or so, this jelly has slowly solidified
(harden), flushing your tank every 6-12 months will remove this jelly before it starts to solidify, once it solidifies its almost impossible to remove (dirty or acid water as known in the industry) before it's too late and 40 or 50 gallons of hot water floods your home.
A TANKLESS WATER HEATER UPGRADE IS A SMART CHOICE
