The FIR2DX provides FIR energy for two with 7 heaters. One heater is in the side wall at the end of the seat so a sole bather can stretch out along the 4’ interior & retain FIR at their back. FIR exposure upon the back is critical to its therapeutic effects. This model is larger than most 2-person FIR saunas and must be used on a 20-amp, 110V circuit. Stereo speakers are included.
The FIR2 has 6 heaters and the same interior dimensions as the DX. There are two rear wall heaters; two front wall heaters; and two underseat heaters. Stereo speakers are optional.
Many companies promote their saunas as if they are built like ours – “non-toxic”, “medical grade”, “hypoallergenic”. They typically aren’t built like ours at all but their clever marketing can fool folks into thinking they are! By using non-aromatic wood, it may seem as if their saunas are also made in a safest manner. The wood selection is only a first step in creating safer saunas, but it can be used as a marketing tool to create the illusion of greater safety.
Most FIR sauna construction is adhesive-based as it’s faster to secure wood to a glue-coated frame with nail guns than by inserting screws, and it allows for the use of thin paneling. Very thin, cheaper wood is typically glued-on like a veneer. They are designed for mass production, economy, and appearance – not for the “purity” required of a real medical-quality sauna.
FIR sellers often downplay the use of glue by claiming to use small amounts of “safe glue”. In every FIR sauna we’ve seen, thick gobs of adhesives secured all of the visible boards – walls, bench, floor, and ceiling to the frames.
Some USA-made carpenter’s glues are labeled “non-toxic” but they are not chemical-free. Most are water-emulsified plastic with a long list of allowed chemical additives (biocides, thinners, preservatives, coloring agents, etc.). Most FIR saunas sold in America today are Chinese or Vietnamese. What is in these glues? While detoxifying, the last thing you want to do is sweat out one toxin and inhale the fumes of another!
Heavenly Heat saunas are built in Arizona and shipped crated. Components are sized smaller than is typical (wall widths are limited to 32” max) to assure the ability to carry each part through any door or stairway. Assembly is simple – mostly by closing stainless steel latches, and they may be disassembled and relocated.
Each sauna is built with counter-sunk non-corrosive steel screws rather than glue, and with much thicker paneling to assure that each sauna is a clean-air environment that is essential for detox. This also yields strong, highly durable saunas with a lifetime warranty on construction, the electrical, and the heaters.
