what is the life expectancy of a water heater?

Answer 1

About ten minutes past the warranty. It depends on your water, climate and use. In general water heaters are built to last the warranty period in most areas.

Answer 2

Water Heater Life Expectancy

Answer 3

Water Heater Life Span

Answer 4

That would depend on the quality of your water. The worse the quality, the shorter the life; gas or electric. You can periodically flush the heater with a hose attached to the drain valve to clean out the sediment. Or get a water conditioner of some sort. This would prolong the inevitable. I've been changing heaters for 19yrs now and the lifespan varies from 5yrs or less (factory defects under warranty) to this one Montgomery Ward dinosaur that was manufactured in 1970 AND STILL WORKING! It has the neat simulated wood access cover and was built very well to last so long. Usually, where I live, (water's not too good) the heaters last 10-15yrs.

Answer 5

The average lifespan will vary greatly with the water quality, brand of heater, and pressure of the incoming water supply. Water Heater Database shows that in Kansas City, AO Smith has an average lifespan of 21 years, State is 17 years, Bradford White is 14 years, and Rheem and Whirlpool have the shortest around 12 and 13.

Answer 6

First of all, I am so happy that someone called the appliance by its correct name: It is a water heater. It takes domestic water (not heated) and heats it to a desired level. As apposed to a "hot water heater", also known as a boiler, that takes hot water and boosts its temperature to steam. Most households do not have boilers or "hot water heaters", but instead have water heaters.

In general, you should expect 10, 15, or 20 years from the appliance, but the older it is, the less efficient it is. Just because it is 20 years old and still working, doesn't mean it is as efficient as newer models.

Factor in your energy usuage and even your type of energy (electric vs gas), whether or not this model can be wrapped in extra insulation or not, and other factors to see if you can save any more.

Also, if you have the funds to spend, many utilities offer substantial rebates to switch to solar. You can put a few panels on the roof to heat the water, along with a circulation pump. When the Sun is not shining, the pump will shut off. This can save hundreds of dollars in the cost of heating water and a good rebate from your electric company can pay for most or all of it.

Answer 7

It depends. You can buy ones ranging from 4 years to 9 years, or more. But the cheaper the water heater (say, $350 or so) the less it's life-span. I was at Home Depot the other week looking at them, and you can get a 9 yr one (Ge I think) for around $450)

Answer 8

Depending on what part of the country your in, because of mineral buildup, usually about 10-12 years. Because if it doesn't start leaking by then the buildup inside will cause the heater to take longer to heat the water and raise your electric or gas usage costs. And if its located inside the house take some preventative measures by replacing before it bursts once it gets about 10 years old.

Answer 9

15 to 18 years

Answer 10

gas water heater lasts 5-10 years, depending whether you drain it very often to clear the sedament out of it,
