What is special about the Heavenly Heat ECO Sauna?
The Heavenly Heat ECO is the most compact sauna in the company’s lineup, designed specifically for apartments, townhomes, and small indoor spaces where a traditional full-size sauna simply won’t fit.
Heavenly Heat Saunas are built with natural wood, zero adhesives, and ultra-low EMFs, and they claim to be the cleanest, safest infrared saunas available today. But does their smallest model the ECO still live up to those claims? And more importantly… does it still perform well despite its compact size? Let's find out.
What are infrared saunas?
An infrared sauna is a type of sauna that uses light, specifically infrared wavelengths, to heat your body directly rather than heating the air around you. Instead of relying on intense, ambient heat like a traditional sauna, infrared panels emit a gentle, penetrating warmth that raises your core temperature from the inside out.
This allows you to sweat more deeply at lower temperatures, making the experience more comfortable while still delivering powerful benefits like detoxification, improved circulation, muscle recovery, and relaxation.
What are the benefits of infrared saunas?
Infrared saunas offer a range of benefits for both physical and mental well-being:
- Detoxification - Infrared saunas heat the body from the inside out, helping you sweat at a lower temperature than traditional saunas. This deep, penetrating heat supports the release of stored toxins from the body through the skin pores, promoting detoxification and cleansing. Because infrared works more gently, you can often sweat more efficiently and comfortably, which makes detox sessions easier on the nervous system.
- Relaxation and Stress Relief - Infrared light stimulates the parasympathetic nervous system, helping the body shift out of a stressed state. The gentle warmth relaxes muscles, releases tension, and promotes a deep sense of relaxation.
- Improved Circulation - Infrared wavelengths penetrate deep into tissues, warming muscles and dilating blood vessels. This leads to increased circulation and can help to improve cardiovascular health, reduce blood pressure, and enhance blood flow to muscles and organs.
- Skin Health - Steam saunas open up pores and increase blood flow to the skin, which can improve skin tone, texture, and elasticity and collagen production. Sweating may also help to clear out pores and reduce breakouts. Many people notice brighter, clearner skin with consistent infrared sauna use.
- Respiratory Friendly - Unlike steam saunas, infrared saunas don’t add humidity to the air. This makes them ideal for people who struggle with: Asthma, sesonal allergies, respiratory sensitivity and mold-related breathing issues.
- Pain Relief: Infrared heat penetrates deeper than traditional saunas, reaching muscles, joints, and connective tissues. This deeper heat can reduce muscle soreness, ease joint stiffness, speed up reovery after workouts and support chronic pain conditions like arthirits.
- Mental Clarity: Infrared sauna sessions often feel grounding and meditative. The combination of warmth, quiet and increased circulation can help promote mental clarity, reduce anxiety and improve mood.
Setup
The ECO is super easy to build, largely because of its smaller size and lightweight wall panels.
- Can be assembled solo, though two people makes it faster
- Most users can assemble it in 30–45 minutes
- Panels connect with Heavenly Heat’s signature latch system (think Legos for adults)
- Optional white-glove delivery is available for those who prefer full installation (for an additional price)
- No electrician required, you can simply plug into a standard 110V outlet
Build Quality
Here’s where Heavenly Heat separates itself from 99% of the sauna industry:
✔ 100% pure Canadian hemlock wood
✔ No stains
✔ No glues
✔ No plywood
✔ Low VOCs and EMFs
This is a game changer as most sauna companies use adhesives, composite boards, or “non-toxic” coatings that still off-gas under heat. Heavenly Heat completely avoids that. Their units are independently tested for VOCs.
For anyone with mold sensitivity, chemical sensitivity, autoimmune issues, or on a detox protocol this is a massive deal. When you’re investing in a home sauna, especially for detox, mold recovery, or long-term health, the last thing you want is a unit that exposes you to more toxins or high EMFs.
Because the sauna is super compact it's ideal for smaller homes or apartments
Dimensions:
- Width: 31.1 inches
- Depth: 35.8 inches
- Height: 68.1 inches
Features
Because of its compact cubic volume, this sauna heats up fast. Inside the sauna, you’ll find a simple, intuitive control panel with the essentials:
Heating & Controls
- Adjustable temperature up to 185°F
- Adjustable session timer up to 60mins
- Heater on/off button
- Soft-touch interface
- 8mm tempered glass door (excellent heat retention)
Lighting
- Light on/off
- Color-changing LED settings
- Choose between 9 different light settings. Glass cover (no plastic).
Audio
- Built-in Bluetooth speakers mounted behind the ceiling
Ventilation
- A manual adjustable vent on the ceiling for increased airflow
Low EMF Panels
Every infrared panel is positioned behind wooden slats, ensuring your body never sits directly against the heat source to improve comfort and reduce EMF exposure. Heavenly heat uses grounded low EMF/ELF heaters, faraday shielding, and no RF. EMF below 2 mg and ELF below 7 v/m.
This sauna doesn’t include red light therapy, but Heavenly Heat does offer models that integrate red light panels for those who want that option.
Ease of Use & Experience
Before stepping inside, I grabbed my Trifield EMF meter to confirm whether the sauna lives up to its “lowest EMF on the market” claim. An EMF typical safe range is between 3-5mG and most readings landed around 0.3-1.0 mG. This is genuinely one of the lowest-EMF saunas I’ve ever tested. One hot spot was detected near the top corner (common in all saunas, near wiring), but where your head and torso sit, levels remained extremely low.
I started my session at at 140°F and hit the timer. 7 minutes in I began to lighly sweat, 10 minutes full river sweat and by 13 minutes i was drenched. Infrared heat in this sauna feels different, because its so compact. As you sit close to all the panels and the volume is smaller, the heat intensity is noticeably higher than in the 2-person or 4-person Heavenly Heat saunas and allows for very efficient sessions. The sauna has wooden slats to prevent you touching the heaters but you still may need to be careful not to lean too far backwards.
The experience itself was suprisingly cosy and not claustrophic due to the glass door, however I wouldn't recommend it if you're super tall (6'5"+). There's also a small window on the side of the sauna that lets move things in and out of the sauna super easily. For more info watch my full review video here.
Maintenance, Pricing and Warranty
Because the wood is light, you’ll want to lay a towel on the floor to prevent dirt stains, especially if you walk around barefoot like me. A towel also protects the wood from sweat, moisture buildup, and potential mold issues. Other than that, maintenance is minimal.
The 1 person ECO infrared sauna costs $5, 600 at retail, so is definitely a premium model. However you can get 6% off if you use code 'WELLNESSDADDY' at checkout.
Heavenly Heat provides an impressive 10-year warranty on the wood/carpentry and 6 years for electrical components including heater, which speaks volumes about the quality and durability of the materials. This is extremely rare in the sauna industry and shows the comoany expects this sauna to last a very long time.
Who Is It For (and Not For)?
✅ People sensitive to toxins, VOCs, chemicals, or EMFs
✅ Individuals detoxing from mold, heavy metals, or chronic illness
✅ Anyone who wants a premium, ultra-clean infrared sauna
✅ People who want a compact sauna that fits indoors
✅ People with small spaces (Apartments, townhomes, offices etc)
✅ Renters or movers who may relocate the sauna in the future
✅ Solo sauna users (Perfect if you sauna alone and prefer fast heat-up times)
✅ Those on a tighter budget (more affordable than the 2-person or red-light models)
❌ Budget-conscious buyers as this is still a premium-priced model
❌ Those wanting a large social sauna or 2 person sauna
❌ Users who want built-in red light therapy (available in different Heavenly Heat models)
❌ Users who get claustrophic very easily
Final Thoughts
The Heavenly Heat ECO is one of the most impressive compact infrared saunas I've seen. It delivers ultra low EMF's, zero toxins or adhesives, fast heat up times, a compact and easy set up, high durability and a rare 10-year warranty
If you're serious about detoxing, reducing EMF exposure, and getting a deep sweat without dedicating a whole room to a sauna, the ECO is one of the best options on the market.
It’s not the cheapest option, but you’re paying for craftsmanship, safety, and a premium experience that genuinely supports long-term healing.
After a thorough reivew it is Wellness Daddy Certified, and I’d feel confident recommending it to my own family. Use code WELLNESS DADDY to save 6% if you decide to purchase.
