Stainless Steel Cylinders
The manufacturers of Stainless Steel Cylinders all now advocate that ONLY INCOLOY OR Titanium elements WITH AN INCOLOY THERMOSTAT POCKET are fitted. You will find a guarantee exception if one is NOT fitted, then the cylinder warranty will become invalid. The main reason for needing an element with an INCOLOY thermostat pocket instead of the normal copper one, is that there can be electrolytic reactions between the copper and the stainless steel.
in Hard Water Areas Titanium should be used.
