Heavenly Heat ECO Sauna Review - The most powerful infrared sauna?
Time to read 2 min
“The ECO is perfect for me — compact but powerful. It heats fast and feels so clean inside. I love that there’s no glue smell and the design is sleek. For small spaces, it’s exceeded expectations.”
What Makes the Heavenly Heat ECO Sauna stand out?
The ECO Infrared Sauna from Heavenly Heat is their space-saving, single-user model built for smaller homes, apartments, or tight corners. It’s designed to deliver rapid heat-up and high performance with the same purity standards as their larger models: no plywood, no glues, no stains, full wood construction, and engineered low EMF / ELF systems.
It’s meant to offer a premium, clean sauna experience in a compact footprint — essentially bringing Heavenly Heat’s high-end ethos into smaller form.
Real-World Performance
In use, the ECO model warms up impressively fast — users often report getting into a sweat within 10 minutes. The design includes an all-glass front panel and sliding side window to help with ventilation and an open feel without compromising insulation.
It promises temperatures above 165°F, with peaks going past 185°F under ideal conditions. Its wood is FSC-certified Canadian Hemlock, and the sauna boasts ultra-low EMF / ELF performance (EMF below 2 mG, ELF below 7 V/m) via grounded heater design, shielding, and construction.
Because the model is compact and optimized, it achieves more consistent heat for a single user than many larger saunas struggle to deliver evenly.
Product Highlights
Compact But Powerful: Small design optimized for tight spaces with strong heat output.
Pure Materials: 100% non-resinous Canadian Hemlock, zero plywood, no glues or stains.
Low EMF Design: Built with grounded low EMF / ELF heaters, shielding, and low emissions by design.
Fast Heating Capable: Claims to reach 165°F+, and beyond under ideal conditions.
Open, Airy Feel: Glass front panel + sliding side window keep the space from feeling boxed-in.
Plug-and-Play: Runs on standard 120V, no special wiring or electrician needed
Size & Dimensions:
This sauna is comfortable for anyone shorter than 6'2" or 6'3" and 215 lbs. If you're larger than that you may want to look at the 1 Person model.
Cons of the Heavenly Heat Red Light Sauna
Single-User Design: Not suitable if you want to share a session with someone else.
Red / NIR Output Not Emphasized: The focus is mainly on far infrared — if you’re seeking strong red / near-infrared therapy, this model may not match dedicated multi-spectrum units.
Still Requires Preheat: Though fast, you may still wait several minutes before full sweat.
Small Footprint Trade-Offs: Everything is scaled down — heater size, space, and some features — so you won’t get the same “roomy” feel or multi-person flexibility.
Conclusion:
The ECO Infrared Sauna is a standout choice for someone who wants Heavenly Heat’s purity, build quality, and low-EMF philosophy in a single-user, space-efficient package. It’s powerful for its size, fast to warm, and beautifully constructed with no glues, stains, or toxic materials.
If your priorities are clean materials, safety, and reliable performance in a compact form, ECO delivers. But if you’re chasing full red / NIR therapy, or need a sauna for two, you’d want to step up to the full Red Light or combination models.
