Signs you need a new tankless water heater
You should consider replacing your current tankless unit if it:
- Is more than 10 years old. Most tankless water heaters only last 10–15 years. If yours is coming up on that age mark, you might want to start looking at getting a new one.
- Has needed a lot of repairs lately. Repair costs add up quickly. Sometimes, it’s more cost-effective in the long run to invest in a new, efficient unit than to keep repairing your current one.
- Is increasing your energy bills. An increase in energy bills is usually a sign that your unit is losing efficiency. When your bills increase but usage stays the same (and nothing else is wrong with the unit), you should consider looking for a replacement.
- Has an expired warranty. An invalid warranty means the manufacturer will no longer cover the cost of a part on your unit if it dies. That means you’ll have to pay for the entire repair cost yourself.
