Repair vs. Replacement: A Homeowner's Guide
Deciding whether to repair or replace your tankless water heater involves weighing its age, repair history, and efficiency.
Here's a breakdown of key considerations:
- Unit Age: If your unit is under 10-12 years old, a repair is often economical. If it's over 15 years old, replacement may be a wiser investment.
- Repair Frequency: Constant repairs suggest the system is near the end of its life, making replacement a better long-term solution.
- The "50% Rule" Guideline: If a repair costs more than 50% of a new unit's price, replacement is often the more financially sound option.
- System Efficiency: If your energy bills are rising, a new, high-efficiency model could provide significant long-term savings.
- Benefits of Repairing: Repair is great for minor issues on a younger unit, restoring function without the high upfront cost of replacement.
- Benefits of Replacing: Replacement is best for old units facing major repairs, offering better efficiency, a new warranty, and peace of mind.
Here's a quick table to help you decide:
| Factor | Repair is Better | Replacement is Better |
|---|---|---|
| Age of Unit | Less than 10-12 years old, still under warranty | Over 15 years old, or frequent issues after 10 years |
| Frequency of Issues | First or second minor repair | Constant breakdowns, multiple repairs in a short period |
| Energy Efficiency | Unit is still performing efficiently | Noticeable increase in energy bills, older inefficient model |
| Repair Cost | Less than 50% of a new unit's cost | More than 50% of a new unit's cost |
