When repair makes sense

If your tankless water heater is still in good condition and the issue is caused by a part, connection, buildup, or setting, repair may be the right option.

When replacement is better

If your unit is older, frequently breaking down, leaking, or no longer keeping up with your hot water needs, replacement may be the smarter long-term solution.
