Designed for seamless installation and versatile integration, it provides an effortless way to modernize your setup with industry-leading technology.
Low EMF Technology: Spectrum infrared heaters are not only extremely effective, but they boast extremely low EMFs. Electromagnetic Fields (EMF) are energy waves with frequencies below 300 hertz or cycles per second.
High Emissivity: The ability to give off infrared heat is measured in "emissivity" which is an object's ability to emit far infrared energy. Finnmark's incoloy Spectrum+ heaters produce higher emissivity.
Greater Watt Density: Watt Density is the heat flux emanating from each square inch of the heating surface of the element and determines the heater's operating temperature for a given set of conditions.
Engineered for daily use and longevity, each Spectrum Plus™ sauna heater panel kit uses a heavy-duty, commercial-grade power supply. Built to sustain continuous high-demand cycles, this robust electrical architecture ensures dependable and safe operation. Experience complete peace of mind with hardware precision-crafted to meet the highest safety, efficiency, and durability standards in the sauna industry.
Unlock peak thermal therapy and deep cellular detoxification by reaching cabin temperatures as high as 170°F. Powered by proprietary technologies, this system targets the body with optimized wavelengths for intense heat penetration, and you'll enjoy the most profuse sweat available on the market today. It delivers true full-spectrum performance, elevating your recovery routine through improved circulation, muscle relief, and restorative heat shock protein activation.

Cancellations of Custom Orders
Custom or made to order products cannot be canceled or refunded as these products are put into production specifically for your order.
These units, are custom made to your specification or created once you order. Once you place your order they start building your unit. Your warranty will guarantee you a fully functional and operational product. If it is not clear whether your order is custom or made to order, please message or call us.
All sales are final for Custom made and Made-to-order products.
Refunds and Returns
If you need to exchange your product, you may do so. You, as the customer, are responsible for any shipping costs throughout any returns and exchange processes.
Not all orders are available for return once they have shipped. We order our products directly from the manufacturer. Therefore, if the manufacturer will not permit us to return a product, we cannot offer you a return. This often varies on a case-by-case basis; please reach out to us if you would like specific information on your brand and/or product.
Due to drastically increasing LTL/freight shipping costs, any outright returns will incur 25% cancellation fee + return shipping costs. If you are replacing the product with something else, we may be able to help you cover some of the costs depending on the product.
Shipping Times
We promise to do our best to get your order to you as soon as possible. We provide estimated shipping times on the product pages based upon what our suppliers and freight companies tell us, and those estimated shipping times may change or vary without notice (Due to supply chain issues, the steel mills behind on making metal, the manufacturers delayed because of the mills, the overwhelmingly demand on shipping, factory/warehouse and dock workers and so on).
Order delays have proven to be unavoidable and outside of Sauna Heater Supply's control. While this might be frustrating, we ask you to please be patient and understanding with us in these tough times. We thank you for your business and appreciate your patience.
Warranty
Warranties vary depending upon the manufacturer - see individual product pages for details. Warranty damages occur over time and from use. If an item was damaged upon arrival, and not reported within 30 days, that is not a warranty claim.
