This is the ASME version, part 461113, the one specified for commercial pools and for any job where the inspector wants a code stamped heat exchanger.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe TitanTough heat exchanger\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eInstead of a copper exchanger, the ETi 400 uses a direct fire titanium exchanger that Pentair calls TitanTough. Titanium shrugs off the water chemistry that shortens the life of copper, and firing the burner directly against it is how the heater reaches its efficiency figure. Pentair describes it as the toughest exchanger it has built.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFast, quiet heat\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAt 400K BTU the ETi 400 is the largest size in the line, so it reaches the set temperature quickly on a large pool and can bring a spa up without a long wait.
