Steel v Stainless Steel

Stainless steel burner chambers v steel burner chamber. Some ask why not make the burners from stainless steel burner. Although it is commonly understood that stainless steel will not rot out due to moisture brought on by condensation, it is not moisture that wears out a waste oil burner combustion chamber / heat exchanger. The waste oil burner combustion chamber eventually wears down from air moving across its surface creating friction. That is why a stainless chamber and a steel chamber will last about the same amount of years. The big difference you should consider is how poorly stainless steel conducts heat. This makes a steel burner chamber incredibly more efficient.
