When the heat exchanger coil leaks or scales up, this kit replaces the finned copper coil and tube sheet together with fresh O-rings, gaskets, and sealant, so a failed exchanger does not mean replacing the whole heater.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e🚩 PRO TIP:\u003c\/strong\u003e Heat-exchanger work is for a qualified technician only — isolate the gas and water, drain the heater, replace every O-ring and gasket in the kit, and pressure- and leak-test the reassembled heater before returning it to service.
