What are common signs a tankless water heater needs repair?

Common signs include inconsistent water temperature, error codes, reduced water flow, system shutdowns, strange noises, or a complete loss of hot water.

Can a tankless water heater usually be repaired, or does it need replacement?

Many tankless issues can be repaired, especially if the unit is properly maintained. Replacement is typically recommended when the heat exchanger fails, repairs become frequent, or the unit is near the end of its lifespan.

How long do tankless water heaters typically last?

With proper maintenance, tankless water heaters often last 15–20 years, which is longer than traditional tank systems.

What causes tankless water heaters to fail?

Common causes include mineral scale buildup, lack of regular descaling, ignition or sensor failures, venting issues, and undersized or improperly installed systems.

Is tankless water heater repair expensive?

Repair costs vary depending on the issue. Minor component repairs are often affordable, while major internal failures may make replacement the more cost-effective option.

Should I replace my tankless water heater with the same model?

Not always. When replacing a unit, we evaluate whether your current model is properly sized and if newer, more efficient options would better fit your household’s usage.
