You will need 2 power outlets to run this sauna: one 20 Amp outlet for the traditional Harvia heater, and another outlet for the infrared panels (15 Amps required / 20 Amps recommended)*

*The infrared panels require at least a 15 amp circuit. However, for optimal performance Finnmark recommends running them on a 20 amp circuit at 240V. While this may cost more up front for installation of the outlet, it will save you money in the long run on your electric bills, and will heat the infrared panels up faster and hotter.

In the USA, the “lifetime” of an infrared sauna is considered 7 years. Many sauna brands offering a “lifetime warranty” know this and use it against you after 7 years of ownership. Your Finnmark Design’s sauna comes with a 10-year warranty, giving you peace of mind that after 7 years you are still covered.

Spectrum Plus™  infrared heaters (UL Listed) have an estimated operational life of 40,000 hours and the Carbon 360° heaters have an estimated operational life of 30,000 hours. Using your sauna 5 times per week, your Spectrum heaters can last up to 130 years. 

The Spectrum Plus™ Incoloy heaters have an unconditional lifetime warranty. No other sauna brand is that confident in their heating elements. 

The Finnmark Limited Lifetime Warranty

Finnmark Designs warrants to the original purchaser (“you”) the following regarding your new sauna, when (a) is installed in accordance with installation instructions provided, (b) is properly and reasonably maintained, and (c) has not been subjected to damage, misuse, or abuse, and (d) is for residential use only (for residential warranty to apply.)
