About Tankless Freeze Damage Repair

When unexpected winter freezes hit Flossmoor, Illinois, outdoor and garage-mounted tankless water heaters are vulnerable to severe freeze damage. When power goes out or wind blows freezing air into exhaust vents, water trapped inside the small copper tubing freezes, expands, and splits the pipes. Homeowners often discover freeze damage when power returns and water pours out of the bottom of the heater cabinet. Our emergency technicians repair burst heat exchanger tubes, replace cracked plastic water manifolds, install fresh ceramic freeze-protection heaters, and install wind-resistant backdraft dampers. We get your unit running safely again and show you how to protect it during future winter storms.

Common Problems We Solve With Tankless Freeze Damage Repair

Water Gushing From Cabinet After Freeze

Thawing pipes burst inside the cabinet, spraying water over burners and electrical boards in Flossmoor, Illinois.

Split Copper Exchanger Tubing

Ice expansion splits the thin copper tubing inside the primary heat exchanger coil.

Failed Ceramic Anti-Freeze Blocks

Burned-out internal electric ceramic freeze protection heaters fail to keep pipes warm.

Tankless Freeze Damage Repair Pricing Factors

Backdraft Damper Installation

Adding an external mechanical backdraft flapper to prevent wind freezing involves extra labor.

Tankless Freeze Damage Repair Questions

Can a freeze-damaged tankless heat exchanger be repaired in Flossmoor, Illinois?

Why did my tankless heater freeze if it has anti-freeze protection?

Our Navien tankless unit started flashing error code E003 at 6:30 AM right before work. The technician arrived in under 45 minutes with a digital manometer, identified an inlet gas regulator drop, cleaned the flame rod, and had our showers running hot before 8:00 AM.

Two other plumbing companies insisted our 7-year-old Rinnai needed total replacement because of a water leak. The tech from TWH PRO's pulled the cabinet front, spotted a simple degraded bypass O-ring, replaced it for a fraction of the cost, and descaled the unit perfectly.

Running a busy restaurant kitchen without hot water means instant health department closure. When our commercial cascade bank locked out on a Saturday evening, their commercial specialist arrived within 38 minutes, cleared a clogged neutralizer trap, and saved our dinner service.
