I would like to install this outside my bedroom on deck. Can it be done
or do you make exterior infrared for 4 or 5 persons?
Outdoor saunas have traditional electric heaters in them because infrared is not effective in overcoming cool ambient air temperatures. For example, if it is 50 degrees outside, the infrared heaters will struggle to get the air in the sauna warm enough to be comfortable, and assist in your sweat.
Infrared is thermal energy, mostly heating what it bumps into. It really does not directly heat the air. Traditional sauna heaters heat the air, and can overcome cold (even sub-zero) outdoor temperatures.
Also, the infrared saunas are not designed for outdoor use. Rain or snow would damage them.
