Read through our quick answers to the most common questions regarding home tankless water heater repairs.
Tankless systems feature sensitive sensors. Sudden shutdowns are usually caused by heavy mineral scale blocking the heat exchanger, a dirty flame rod, or restricted venting.
A descaling flush pumps cleaning solutions through the unit to remove hard calcium scale. In Houston, this must be performed annually to prevent heat exchanger damage.
This is known as a cold water sandwich. It happens when the unit cycles off briefly between consecutive hot water uses, which can be minimized with proper flow adjustments.
Leaks inside the casing usually indicate a cracked copper heat exchanger caused by mineral stress or freezing, which requires replacing the core component.
