When should you replace your water heater?

Replacement is the right call when repair no longer makes sense. Consider a new unit if:

  • Your water heater is near or past 10 to 12 years old
  • The tank itself is leaking, which is not repairable
  • You have rusty hot water or a corroded tank
  • You are paying for repeated repairs
  • The unit no longer keeps up with your household’s hot water needs
  • You want better efficiency and lower energy bills

If you are not sure whether to fix or replace, start with our water heater repair page, or just call and we will give you an honest assessment.

How long does a water heater last?

Most traditional tank water heaters last about 8 to 12 years. Tankless units can last longer, often 20 years or more, with proper maintenance. Hickory’s soft city water helps, since less scale and sediment means less wear over time. Once a tank unit is past a decade, planning for replacement before it fails saves you the mess and stress of an emergency.

Choosing the right water heater

This is where a good plumber earns their keep, because the right choice depends on your home and habits.

Tank or tankless?

A traditional tank heater stores and heats a set amount of water, with a lower upfront cost. A tankless water heater heats water on demand, never runs out, takes less space, and lasts longer, at a higher upfront cost. We will walk you through which fits your home, budget, and hot water needs.

Gas or electric?

Your choice often depends on what your home already has. Gas units heat quickly and can be less expensive to run where natural gas is available, while electric units are simpler and work anywhere. If you are switching fuel types, that may involve gas line work or electrical changes, which we will factor in.

The right size

An undersized unit runs out of hot water, and an oversized one wastes energy. We size the unit to your household, considering the number of people, bathrooms, and your peak hot water use. For tank units, we look at the first-hour rating; for tankless, we size by flow rate and temperature rise, which matters more here than you might think because of cold winter incoming water.

Local factors in Hickory installations

  • Soft city water. Hickory’s soft to moderately soft city water is gentle on new units, which helps them last. Wells with harder or acidic water may benefit from treatment to protect the investment. See water treatment.
  • Cold winters. Foothills winters bring colder incoming water and higher demand, which is a key reason correct sizing matters here.
  • Older homes and tight spaces. Many Hickory homes have water heaters in closets, garages, or crawlspaces, and older setups may need code upgrades at replacement time.
  • Fuel availability. Whether natural gas is available on your street can shape the gas-versus-electric decision.
