About Overheat Film Wrap Replacement

The overheat film wrap is a specialized one-time thermal safety fuse wrapped tightly around the entire outer copper shell of the heat exchanger. In Cornwall, Pennsylvania, if an internal water blockage, severe mineral scale hotspot, or dry-fire condition causes the heat exchanger body to overheat, the film wrap melts and snaps open. Because the film wrap is wired in series with the main power supply, a tripped wrap cuts all electrical power to the motherboard instantly to prevent a house fire. Our technicians diagnose the root cause of the overheat, flush mineral scale, and install a brand-new factory OEM overheat film wrap assembly.

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.
