Enhanced Heater Durability with 304 Steel

Marine-grade 304 steel

Superior rust resistance

Longer heater life

Handles high heat

Why upgrade to 304 stainless steel?

Upgrading your heater to marine-grade 304 stainless steel gives it far greater resistance to rust, heat stress and corrosion. It is a small investment that meaningfully extends the life of the hardest-working part of your tub.

  • Corrosion resistant — 304 stainless stands up to constant water and heat far better than standard steel.
  • Longer lifespan — a more durable firebox means fewer worries and a longer-lasting heater.
  • Handles intense heat — the grade copes comfortably with repeated high-temperature fires.
  • Keeps its looks — resists staining and discolouration over years of use.

Your heater endures the toughest conditions in the tub — direct flame on one side, hot water on the other. Marine-grade 304 stainless steel is chosen precisely because it shrugs off that combination of heat and moisture.

An upgrade that pays for itself

By resisting the corrosion that eventually wears out ordinary steel, the 304 upgrade keeps your heater performing like new for longer. It is the sensible choice for anyone planning years of regular soaks.
