When your hot water heater starts acting up—maybe it’s making strange noises, not heating water efficiently, or even leaking—you’re faced with an important decision: should you repair it or replace it? The answer depends on several factors, including the age of the unit, the cost of repairs, and how well it’s been maintained. Let’s break it down so you can make the smartest choice for your home and budget.
Common Hot Water Heater Problems That Can Be Repaired
Not every issue means your water heater is done for. In many cases, a simple repair can restore full function. Some examples include:
- Faulty Heating Elements: Electric water heaters may stop producing hot water if one of the heating elements burns out. Replacing the element is typically quick and cost-effective.
- Thermostat Issues: A broken thermostat can prevent proper temperature regulation, leading to lukewarm or scalding water.
- Pilot Light or Igniter Problems: For gas units, relighting or replacing the pilot light or igniter can often solve the issue.
- Sediment Buildup: Flushing the tank to remove sediment can improve efficiency and extend lifespan.
- Leaky Valves: If the leak is coming from a valve (like the pressure relief valve), it may be an easy fix.
If your water heater is otherwise in good condition and under 8–10 years old, these repairs may be worth doing.
When Repairs May Not Be Worth It
In other situations, repair costs may be high enough that replacement makes more financial sense. Watch for these signs:
- Age of the Unit: Most conventional water heaters last about 8–12 years. If yours is at the tail end of that range, putting money into repairs may only buy you a little time.
- Frequent Breakdowns: Constant repairs can add up fast. A newer, energy-efficient model may save money in the long run.
- Leaking Tank: If the tank itself is leaking, it’s time for a replacement. There’s no way to safely or effectively repair a leaking tank.
- High Energy Bills: Older units tend to lose efficiency. Replacing it with a newer model—especially a tankless unit—can result in significant energy savings.
Repair vs. Replacement: Cost Comparison
On average:
- Basic repairs (like replacing a heating element or valve): $150–$350
- Major repairs (such as replacing the burner assembly or fixing wiring): $400–$600
- New water heater installation: $1,000–$2,500, depending on size and type
If a repair costs more than 50% of the price of a new unit, replacement is usually the smarter investment.
The Benefits of Replacing an Old Unit
Even if repairs are possible, there are good reasons to consider upgrading:
- Improved efficiency means lower monthly bills.
- Better reliability and peace of mind.
- Warranty protection on a new unit.
- Increased hot water capacity with newer models.
