Scandia 40K BTU Gas Sauna Heater
Product Description
Experience the authentic soul of sauna bathing with America's only gas-fired sauna heater. The Scandia 40K BTU Gas Sauna Heater represents six decades of unwavering commitment to excellence—designed and built by those who understand that true wellness spaces require more than equipment, they demand character.
This isn't just another heater; it's the cornerstone of intentional living. Gas-fired heat delivers something electric simply cannot—the warm, enveloping embrace that transforms your sauna from a room into a sanctuary. When you choose gas, you choose the quality of heat that has been revered for generations, the kind that penetrates not just muscle and bone, but spirit and purpose.
Built with 100% stainless steel construction and featuring the industry's largest rock tray (holding up to 150 pounds of stones), this heater instantly transforms your space into either a traditional dry sauna or a steam sauna environment. The sealed combustion design eliminates any risk of oxygen depletion or flue product leakage—engineering that prioritizes both safety and the uninterrupted flow of your wellness ritual.
More efficient than electric heaters, gas operation costs up to 50% less to run while eliminating the frequent replacement of costly heating elements. Whether you're creating an off-grid retreat or enhancing your backyard wellness space, this heater requires only a propane tank to deliver profound therapeutic experiences.
Available Configurations:
- Natural Gas or Liquid Propane fuel options
- Standing Pilot or Piezo ignition systems
- Horizontal or Vertical venting configurations
- Standard 60-minute or optional 24-hour timer systems
The Therapeutic Patio orders are made to order. Most products are shipped within 48 hours, but some product lead times range between 2 to 4 weeks. Shipping time can be confirmed after order is made or by contacting us right before your order.
Warranty: Features a comprehensive 10-year warranty on the heater unit (residential installations) and one-year warranty on parts. Commercial installations receive a one-year warranty on the complete unit—because when you build something meant to endure, the warranty must reflect that commitment.
Note: Professional installation by a licensed HVAC technician required for warranty validation and optimal safety.
