EOS Sauna Heaters

Yes. We confirm that EOS remains one of the few brands that manufactures 100 percent of its components in Germany. In the US market, they are recognized as a premier luxury brand due to their industrial-grade tolerances, heavy-duty stainless steel, and long-term durability.

The Invisio series is a hidden heater designed for installation behind a partition or under the benches. We find this is a preferred solution for minimalist modern designs or commercial spas where the owner wants to maximize space and prevent users from touching the hot stones.

The price reflects the superior build quality. EOS uses reinforced stainless steel and heating elements that do not come into direct contact with the stones in several models. We note that this indirect heating prevents thermal shock to the elements, extending the unit’s lifespan significantly.

Yes. Almost all professional EOS units sold in the US do not have on-unit controls. They must be paired with an external digital controller like the Emotec or EmoTouch series, which are renowned for their high-resolution color screens and exceptional precision.

Yes. When integrated with the SBM-App module and a compatible digital hub, you can operate your sauna via WiFi. We find this is a high-demand feature for US homeowners who wish to initiate the heating process from their office or while traveling back from the gym.

The Bi-O series features an integrated water evaporator, allowing you to toggle between a traditional dry Finnish sauna and a soft sauna with higher humidity. We suggest this hybrid solution for users who want a versatile experience without the cost of a separate steam generator.

Yes. We offer a specific line of EOS heaters that are fully UL and CSA certified for North America. It is critical to ensure you are purchasing a US version engineered for 240V/60Hz rather than a European 400V model, as the electrical internal components are vastly different.

In the US market, EOS typically provides a 2-year warranty for residential applications. We emphasize that this warranty is strictly contingent upon installation by a licensed electrician and adherence to all factory-specified mounting clearances.

A safety lockout usually occurs if the temperature sensor is mounted improperly. Because EOS heaters are high-output units, the sensor must be mounted precisely as directed in the manual—typically directly above the unit on the ceiling—to prevent the safety limiter from tripping prematurely.

Hidden Invisio systems utilize a specialized Water Infusion Set. This consists of a stainless steel funnel and a silicone hose that mounts to the interior wall. You simply pour water into the funnel, and it is guided directly onto the hidden rock chamber beneath the bench.

Yes. We find that hidden heaters are often considered the safest option because the hot stones and heating elements are completely inaccessible to the bather. This makes them the definitive standard for high-end US commercial spas and families with young children.

No. By utilizing optimized air convection baffles, the Invisio series pulls cool air from the floor and pushes heat out through a partition. We have verified that these units reach therapeutic temperatures as efficiently as standard floor-standing models.

Error E100 indicates a Temperature Sensor Fault, meaning the control hub has lost communication with the probe. We suggest checking the sensor cable for pinches sustained during installation or verifying the terminal connections on the main circuit board.

The red triangle is a general fault indicator. You must touch the cabin icon on the screen to view the specific error code. Common issues include a tripped safety temperature limiter or a door sensor timeout if the sauna door has been left open during preheating.

After a power flicker, the unit may enter a standby or safety mode. We recommend turning the main breaker off for 60 seconds to reset the computer. Once power is restored, you may need to re-verify the time and date on the panel before the system permits a new session.

Yes. Because of the high-speed convection design, the intake at the floor level can accumulate lint and dust. We recommend vacuuming the underside of the heater every six months to ensure the intake reflectors remain clear and the unit operates within its cooling parameters.

German engineering protocols are specific about stone reheat times. We suggest waiting approximately 10 minutes after adding water to allow the stones to return to their peak thermal temperature. This ensures the next application creates dry steam rather than cooling the stones.

EOS heaters and digital controls are not rated for direct exposure to the elements. They must be installed inside a weather-proof, insulated sauna cabin or a climate-controlled room, as the sensitive electronics are susceptible to freezing temperatures and high humidity.

We emphasize that the sensor must be mounted horizontally on the ceiling, usually 12 to 18 inches away from the wall. If it is mounted too low or too close to a vent, the high-precision German logic will detect an imbalance and prevent the heater from firing.

We require the use of high-density EOS Cubius stones. These stones are specifically cut to fit the vertical fin design of the Mythos and Cubo series, ensuring optimal airflow and preventing elements from being choked by irregular rock shapes.

Yes. The Emotec and EmoTouch power units require a 120V neutral wire to power the internal logic boards and the color display. We suggest verifying that your 240V run includes this third conductor before finalizing the electrical installation.

We recommend the 9kW EOS models for sauna rooms up to 495 cubic feet. If your sauna features significant glass walls or stone masonry, we suggest moving to a 12kW or 15kW unit to ensure the heat remains consistent at the bench level.

Because the heater is hidden beneath the bench, the funnel set allows you to pour water from a comfortable standing position. The stainless steel funnel and silicone tubing guide the water safely onto the hidden stones without splashing wood surfaces.

Yes. Per US safety standards, residential sessions are capped at 60 minutes. However, we note that professional commercial modes can be enabled for up to 12 or 24 hours of operation if the unit is installed in a monitored spa or gym environment.

Yes. EOS maintains a stable supply of replacement parts for all US-certified models. We find that replacing individual incoloy elements is a straightforward process for a licensed electrician, preserving the high-value stainless steel chassis of your heater.
