Repair vs. Replacement: What’s the Best Option?
When your tankless water heater starts acting up, the big question is whether to repair or replace it. Here’s how we help you decide:
- Age Matters: If your unit is relatively new, a repair might be all it needs. Older units, however, might be better candidates for replacement.
- Cost Considerations: Sometimes, the cost of repairs can approach the price of a new system. If that’s the case, replacement is often the smarter choice.
- Energy Efficiency: Newer models are more energy-efficient, which can save you money in the long run.
We’ll walk you through your options and help you make an informed decision.

What Are the Most Common Tankless Water Heater Repairs?
Tankless water heaters are reliable, but occasional repairs become necessary due to wear and tear or improper maintenance. Here are the top issues homeowners encounter:
1. Mineral Buildup
Hard water is a common culprit for tankless water heater woes. Over time, minerals like calcium and magnesium collect in the system, clogging pipes and reducing efficiency.
- Signs: Reduced water flow, fluctuating water temperature, or error codes.
- Solution: Descaling the system or installing a water softener.
2. Ignition Failure
No hot water? Yikes! If your heater won’t ignite, it might be due to a gas supply issue, dirty burners, or a faulty ignition system.
- Signs: Cold water when the system should be operating, or ignition error messages.
- Solution: Inspect gas lines, clean burners, or replace ignition components.
3. Cold Water Sandwich
Ever notice a blast of cold water before the heater catches up? That’s the infamous cold water sandwich.
- Cause: Lag between the system heating water and delivering it to your faucet.
- Solution: Installing a recirculation pump or adjusting usage habits.
4. Overloading the System
Tankless systems have their limits. Running multiple faucets, showers, or appliances at the same time can overwhelm them.
- Signs: Water temperature drops or inconsistent heating.
- Solution: Upgrade to a larger unit or install multiple systems.
5. Blocked Exhaust or Air Supply
Proper ventilation is essential for tankless water heaters, and blockages can cause serious problems.
- Signs: Error codes, abnormal noises, or system shutdowns.
- Solution: Clear vents and ensure proper installation.
6. Sensor Issues
Temperature sensors can fail or become miscalibrated, leading to water that's too hot, too cold, or inconsistent.
