About Heat Exchanger Leak Repair

The heat exchanger is the beating heart of any tankless water heater, absorbing intense burner heat to warm passing water instantly. In Cornwall, Pennsylvania, acidic water, aggressive mineral scale hotspots, and sub-freezing cold snaps cause microscopic pinholes and fractured copper joints inside combustion chambers. When an exchanger leaks, water sprays directly onto internal electronics, shorting circuit boards and extinguishing burner flames. Our technicians assess whether the leak originates from serviceable O-ring unions, condensation fittings, or structural tubing fractures. If replacement is required, we manage the installation under manufacturer warranty whenever applicable.

Common Problems We Solve With Heat Exchanger Leak Repair

Internal Water Spraying

Water leaks inside the cabinet, shorting out electrical wiring in Cornwall, Pennsylvania.

Chamber Corrosion Stains

Green copper oxidation crust forms along the exterior of burner fins.

Sudden Loss of Flame

Dripping water falls onto burner plates, putting out flames mid-cycle.

Heat Exchanger Leak Repair Questions

Can a cracked tankless heat exchanger be welded or patched in Cornwall, Pennsylvania?

No, high pressure and thermal cycling make welding unsafe. Leaking heat exchanger cores must be replaced. Call (888) 905-6092 to discuss options.

Why is water dripping from the bottom vents of my tankless unit?

This indicates an active internal leak from the heat exchanger, buffer tank, or water connections. Call (888) 905-6092 immediately to prevent floor damage.

Is heat exchanger replacement covered under warranty?

Most major brands cover heat exchangers for 10 to 15 years if annual maintenance records are maintained. Call (888) 905-6092 to verify your coverage.

What Our Customers Say

Real reviews from homeowners and business owners we have helped.

Our Navien NPE-240A started beeping error code E003 on a freezing Tuesday morning. Marcus from TWH PRO's arrived within 40 minutes, tested the gas manifold pressure, cleaned the flame rod, and replaced a worn spark igniter on the spot. Having hot water back before our kids woke up was huge.

We went three days with lukewarm showers because our electric EcoSmart 27 kept tripping breakers. The technician tested the continuity of all three heating elements and found two had burned out from mineral scale. He swapped in genuine OEM canisters and descaled the chambers. Steaming showers are back.

Our restaurant dishwasher tripped a sanitation temperature alarm during Friday dinner service. TWH PRO's sent a commercial technician immediately. He cleared a clogged air intake screen on our cascaded Rinnai rack and re-calibrated the water servo in under an hour, saving our dinner service.
