Collection: Scandia Sauna Heaters

Electric sauna heaters from Scandia's Ultra-Sauna line represent the highest standard in electric sauna heating technology. These are considered one of the best electric sauna heater solutions engineered with the same exacting standards Scandia applies to their commercial installations.

Superior Materials and Construction

The foundation of every Scandia electric heater is 321-spec stainless steel construction. This 321-grade incorporates titanium stabilization that prevents intergranular corrosion, the primary failure mode in high-heat applications. 

When heating elements cycle through extreme temperature ranges thousands of times, standard materials develop microscopic cracks along grain boundaries. Titanium-stabilized 321 steel resists this degradation, ensuring decades of reliable service.

This material choice reflects Scandia's commercial heritage. For heaters that function continuously, the priority in material selection is reliability rather than cost control, reducing the risk of failures and supporting long-term performance.

Scandia structures its electric line into three distinct capacity ranges:

• Small Series heaters serve compact residential saunas, usually ranging from 3 kW to 4.5 kW output. These units efficiently heat sauna rooms up to 210 cubic feet, making them ideal for personal home saunas and small commercial applications.
• Medium Series represents the standard for high-end home saunas and mid-size commercial installations, with outputs from 6 kW to 9 kW. These units handle sauna volumes from 294 to 616 cubic feet, providing the power needed for serious home enthusiasts and boutique wellness facilities.
• Large Series heaters deliver high-capacity output for large-scale wellness centers, ranging from 12 kW to 18 kW. These professional-grade units heat volumes from 980 to 1680 cubic feet, serving multi-user commercial facilities that demand continuous operation and consistent performance.

Each series maintains Scandia's commitment to 321 stainless construction, elevated rock tray protection, and UL certification, ensuring that regardless of capacity, you're receiving the same engineering excellence that has defined the brand for sixty years.

Scandia offers gas heaters in two primary output ratings: 40,000 BTU and 80,000 BTU. Rather than focusing on the budget, the key is matching the heater’s BTU capacity to the volume of your sauna.

The 40K BTU model efficiently serves sauna rooms up to approximately 616 cubic feet. This capacity suits most residential applications and smaller commercial saunas, providing ample heating power without oversizing the system.

The 80K BTU model handles larger installations, heating volumes up to 1680 cubic feet effectively. Large home saunas, commercial wellness centers, and multi-user facilities benefit from this higher capacity, which maintains consistent temperatures even with frequent door opening and higher user traffic.

Proper sizing ensures efficient operation, appropriate heat-up times, and long equipment life. Undersized heaters may run continuously, struggling to maintain temperature. Oversized units may short-cycle, creating temperature fluctuations and reducing efficiency. Matching BTU capacity to actual sauna volume optimizes performance and longevity.

Dual-Fuel Capability

Scandia gas heaters accommodate both propane and natural gas applications, with field-convertible configurations allowing adaptation to available fuel sources. This flexibility makes these units suitable for virtually any location, from urban homes with natural gas service to rural properties relying on propane delivery.

Professional installation ensures proper venting configuration, whether direct vent (through exterior walls) or vertical vent (through roof), and appropriate gas pressure regulation for optimal combustion efficiency and safety.
