Glass Enamel VS Stainless Steel

There is lots of different opinions on whether Stainless Steel is better than Glass Enamel to help you see through the confusion we will advise you of the pros and cons of each.

Glass Enamel is by far the most common type of tank in Hot Water Systems. More than 80% of electric, solar and gas storage systems use a glass enamel lined tank.


  • Glass enamel is extremely resistant

  • Cheaper to manufacture

  • Handles high temperatures


  • Requires change of anodes to prevent rusting

  • Last only up to 15 years

  • Anode to be replaced every 5 years at extra cost

  • Heavier

Stainless Steel is the most popular and more premium product used for hot water system tanks.


  • Drastically lighter

  • Rust Resistant (no anode required)

  • Generally lasts longer

  • Stronger material

  • Less likely to have issues


  • More expensive

  • Different grades have different levels of quality

  • Lower grades can last less time than a glass enamel

Glass enamel is still very good value providing you can remember to replace the anode, it’s worth spending the extra on stainless steel providing its a high grade stainless steel.
