Notes

A storage-tank water heater is a daily necessity, and failures can create both comfort loss and leak risk. Energy.gov notes storage water heaters last about 10-15 years; the midpoint (12.5) is used here to stay realistic while still conservative.

Repairs under the threshold are often sensible for common service parts such as an anode rod, thermocouple, heating element, or T&P valve-particularly when the tank itself is not corroded and the unit is under about mid-life. If the tank shows rust, water at the base, or recurring temperature instability that points to broader corrosion, replacement is usually safer because a rupture can cause property damage.

The price used reflects a popular 50-gallon gas tank water heater listing at a major home-improvement retailer; tankless or high-efficiency models can cost more upfront.
