Tankless Water Heater Repair vs. Replacement

If your tankless water heater is breaking down frequently, consider replacing it rather than repairing it again. Sometimes, repairs are more cost-effective at the time, but it’s good to be ready for when you have to replace your tankless water heater.


It’s better to repair your tankless water heater if your unit is newer and has a specific issue. However, if your unit is getting old and needs many complex repairs, replacing it might be more cost-effective than repairing it over and over.
