Should You Repair or Replace Your Water Heater?
- Age matters — If your water heater is over 10 years old, replacement is usually the smarter move.
- Rising energy bills? Older units lose efficiency and cost more to run.
- Leaks = replace — A leaking tank can’t be repaired safely.
- Recurring issues like rust-colored water or sediment buildup often signal the need for a new unit.
- If repairs cost over 50% of a new unit, replacement is more cost-effective.
- Modern models offer better efficiency and may qualify for energy rebates in Missouri.

When your hot water heater starts acting up, it’s easy to wonder: should I repair it—or is it time to replace it altogether? At Silverback Plumbing, we help Wentzville homeowners make smart, cost-effective decisions that keep the hot water flowing without draining your wallet.
Here’s your go-to guide to know when it’s time to fix or forget your current system.
🔍 Start With the Age of the Water Heater
One of the biggest indicators of whether to repair or replace your water heater is its age:
- 0–5 years old: Most water heater repairs can be handled quickly and affordably.
- 6–10 years old: Repairs may still make sense, but efficiency is likely dropping.
- 10+ years old: Replacement is usually the smarter option—especially if you’re facing repeated plumbing issues.
Traditional tank water heaters typically last 8–12 years, while tankless water heaters can stretch up to 20 years with proper plumbing maintenance. If yours is pushing the upper limit, investing in a new unit now can prevent a costly plumbing emergency later.
⚡ Is It Energy Efficient?
Older water heaters—especially pre-2010 models—use more energy and take longer to heat water. Ask yourself:
- Are your energy bills increasing every month?
- Does it take longer for water to get hot?
- Are you running out of hot water quickly?
Modern units, especially Energy Star–rated water heaters, are built to heat water more efficiently. If your current system is working overtime just to keep up, replacing your water heater could save money long term.
💧 Evaluate the Performance Issues
Some hot water issues are minor and can be repaired. Others mean your system is nearing failure. Here’s a breakdown:
| Issue | Repair or Replace? |
|---|---|
| Pilot light out | ✅ Repair |
| Faulty thermostat | ✅ Repair |
| Sediment buildup | ⚠️ May flush or replace depending on age |
| Tank leaking | ❌ Replace |
| Rusty water | ❌ Replace (possible corrosion) |
If your system is experiencing recurring plumbing problems, your money is better spent on a new water heater installation.
💰 Cost Comparison: Repair vs. Replacement
Before you make a decision, weigh the cost:
- Water heater repair costs range from $150–$600
- Water heater replacement costs typically range from $1,000–$2,500
If repairs are over 50% the cost of a new unit, replacement is usually the smarter long-term option. Plus, Missouri homeowners may qualify for energy efficiency rebates, which help lower the price of upgrading your system.
