Ultra Electric Sauna Heater
Ultra Electric Sauna Heater

The Scandia Ultra 12240 or 12208 Electric Sauna Heater provides exceptional heating performance for large sauna rooms up to 980 cubic feet, combining robust power with long-lasting durability. Constructed entirely from stainless steel, including spec 321 jet engine stainless steel element channels, this heater is engineered for maximum strength and efficiency under high-heat conditions. Its innovative steamer tray ensures complete vaporization, keeping the heating elements dry and extending their lifespan, while high-density imported rocks retain heat longer for a consistently warm and inviting sauna environment. Versatile voltage and phase options make installation adaptable to various electrical configurations. Proudly made in the USA, the heater includes user-friendly controls and premium sauna stones, delivering a reliable, high-quality sauna experience. The Scandia Ultra 12240/12208 combines professional craftsmanship, energy-efficient performance, and precise steam generation, making it an ideal centerpiece for spacious residential or commercial saunas.

  • Heats Up To 980 Cubic Feet – At 12 kW, this heater is sized for large sauna rooms, reaching bathing temperature without being pushed to its limit, which extends element life in daily use.
  • Spec 321 Stainless Steel Construction – The same grade of stainless used in jet engine applications resists corrosion from steam and humidity, which is what usually ends the life of a sauna heater.
  • Steamer Tray For Full Vaporization – Water poured over the rocks is fully converted to steam, so you get an even löyly without water spitting or collecting in the tray.
  • High-Density Imported Rocks Included – Dense stones store more heat and release it slowly, holding the room steady between pours rather than dropping after each one.
  • Flexible Voltage And Phase – Available in 208V or 240V, single or three phase, plus a 480V single-phase configuration for commercial buildings with 480V service.
  • Made In The USA With A 10-Year Shell Warranty – Backed by a 10-year warranty on the heater shell and 1 year on electrical components, with parts available directly from Scandia.
  • Model: 12240 (240V) / 12208 (208V)
  • Output: 12 kW
  • Room Capacity: Up to 980 cu ft
  • Dimensions: 18" W x 26" D x 29" H
  • Material: Spec 321 stainless steel
  • Voltage & Amperage: 240V / 1 Phase (50 A), 208V / 1 Phase (57.7 A), 240V / 3 Phase (29 A), 208V / 3 Phase (33.3 A), 480V / 1 Phase
  • 480V Note: At 480V, the 12 kW Ultra is single phase only. There is no 480V three-phase configuration for this model.
  • Certification: UL listed in 208V and 240V configurations. The 480V model is not UL listed.
  • Control: External control box, sold with the heater
  • Timer: 24-hour or 60-minute timer, customer's choice
  • Thermostat Location: On the heater or inside the control box. On 480V units the control box has no room for both a 24-hour timer and the thermostat, so a 24-hour timer requires the thermostat on the heater, and a thermostat in the control box requires the 60-minute timer.
  • Stones: High-density imported sauna rocks included
  • Warranty: 10 years on the heater shell, 1 year on electrical components
