The Scandia Ultra Gas Model 245 is a high-performance 40,000 BTU vertical venting sauna heater engineered to provide powerful warmth for sauna rooms up to 616 cubic feet. We provide this 100% stainless steel model as the primary solution for large residential or commercial environments where gas is preferred over high-wattage electric units for its rapid heat recovery and lower operational costs. This specific model is the right choice for installations requiring a vertical exhaust system, featuring a sealed combustion design that ensures clean operation by keeping flue products out of the sauna while maintaining optimal oxygen levels. By utilizing natural gas or liquid propane and incorporating a generously sized rock tray for rich steam production, we ensure the Model 245 delivers a durable and therapeutic retreat that combines industrial-grade reliability with the refined performance of a premium gas-fired sanctuary.
