It is the piece that actually does the heating, and it is also the piece that eventually gives out, usually from years of aggressive water chemistry or from scale that has built up inside the tubes and cooked them.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHeat exchangers are rated to the heater. This one is the 250K assembly, so read the data plate on your heater and confirm both the model and the BTU rating match before buying.
