Home depot 75 gallon hot water heater

For homes with five people or more, you may need to consider a 75-gallon (average price of $900 to $3,000) or an 80-gallon (average price of $1,000 to $3,200) water heater.

Based on the manufacturer's suggested service life, the life expectancy of a water heater is about eight to 12 years.

If you were to buy a 12-year-warranty heater, likely the only difference between it and a 6-year-warranty one would be extra anodic metal: either a larger-diameter hex anode, or a normal one along with a half-length outlet rod in the hot port.

Typically, the rule-of-thumb is that you want a 40 gallon tank for 1 to 4 people, a 50 gallon tank for 4 to 6 people, and a 50 gallon high recovery or 75 gallon tank for 6 to 8 people.
