Mr. Steam Element MS 12kW 208/1 is a high-capacity replacement heating element engineered to restore factory performance in MS Series—specifically MS Super 2—steam generators running on 208-volt single-phase power. Delivering a full 12 kW of output, it drives rapid heat-up and steady, even vapor so larger enclosures reach and hold target temperatures without overshoot or short cycling. The robust 5 lb assembly uses steam-rated, corrosion-resistant construction to withstand continuous heat, humidity, and mineral exposure inside the generator bay, protecting terminals and preserving long service life. Designed for a clean OEM fit, it aligns with Mr. Steam control logic and mounting geometry for plug-and-play installation that minimizes downtime and keeps safety interlocks intact. Choose this element to maintain efficient operation, predictable comfort, and consistent steam quality in demanding residential or light commercial settings.

  • 12 kW steam performance – High-capacity heating brings the enclosure to temperature quickly and sustains dense, even vapor. Abundant output minimizes cold spots and recovery time, delivering smoother, spa-quality comfort throughout extended sessions in appropriately sized steam showers.
  • 208V single-phase integration – Designed for 208V single-phase electrical systems to simplify planning and hookup. Stable supply reduces nuisance trips and voltage sag, supporting consistent steam production, accurate control response, and predictable operation during warm-up and long daily use.
  • MS Series native fit – Precisely tailored for Mr.Steam MS systems with matched interfaces and control logic. Plug-and-play compatibility preserves intended features, shortens commissioning, and avoids adapters or rewiring that can complicate service and reduce long-term reliability.
  • Steam-rated durability – Engineered to endure sustained heat, humidity, and mineral exposure inside generator bays. Corrosion-resistant components and secure terminations protect critical elements, extend maintenance intervals, and maintain reliable performance through frequent residential or light commercial duty cycles.
  • Installer-friendly setup – Clear connections and accessible layout streamline replacements or upgrades, minimizing downtime. Efficient routing keeps cabling tidy and service points reachable, helping technicians restore full functionality quickly and maintain peak performance with routine inspections and adjustments.
