The Hele Nano can be installed in many outdoor environments depending on your preference and available space. Popular locations include:

• Backyard or garden
• Terrace or rooftop
• Balcony
• Poolside area
• Beach or lakeside property
• Forest or natural retreat settings

The sauna must be placed on a stable, level foundation according to the installation guidelines.

Yes. The sauna can be installed on hard, level surfaces such as terraces, rooftops, decks, or paved areas.

The surface must be load-bearing, stable, and capable of supporting the full weight of the sauna and its users. The sauna’s skid base provides the necessary clearance for airflow and should not be altered or blocked.

If installing directly on soil, the ground should first be prepared with a stable, well-draining base.

Typically, the topsoil is removed and replaced with compacted gravel, sand, or similar load-bearing material. Concrete tiles or pads should then be placed and leveled beneath the sauna legs to provide proper support.

Adequate airflow beneath the sauna should always be maintained to prevent moisture buildup.

The Haljas Hele Nano is delivered fully assembled for easy setup. Installation typically involves placing the sauna in its final location, adding sauna stones to the heater, and attaching the door handle.

The heater requires a 6 kW, 400V electrical connection, so a licensed electrician is typically needed to complete the electrical hookup. Once connected, the sauna is ready to enjoy.

The sauna can be positioned using a forklift from below or lifting straps during placement. Because the Hele Nano does not have roof lifting mounts, straps are used when lifting from above.

Professional freight carriers or installers typically handle the positioning.

Yes. Haljas saunas are designed for year-round outdoor use, even in extremely cold climates. The structure has been tested in temperatures as low as -13°F.

The sauna features durable tempered glass and insulated construction to maintain heat and ensure reliable performance in winter conditions.

The ideal sauna temperature varies by personal preference, but Haljas saunas typically feel most comfortable between 149–158°F.

Because the sauna features a large glass surface that gently radiates heat, many users find that slightly lower temperatures still feel pleasantly warm and relaxing. We recommend experimenting within this range to find the temperature that feels best for you.

No. The sauna uses high-quality double-glazed mirror glass approximately 30 mm (1.18 in) thick, designed to retain heat effectively.

The insulating performance of this glass is comparable to roughly 6 cm (2.36 in) of solid wood, helping the sauna maintain a comfortable temperature even in colder climates.

During daylight, the mirror glass reflects the surroundings, making it very difficult to see inside the sauna from the outside. At night, when the interior lights are on, the inside may become partially visible.

The Hele Nano’s lighting is positioned beneath the benches and along the exterior eaves, which reduces interior visibility and enhances the reflective effect of the glass for added privacy.

The Haljas Hele Nano is designed to work with an electric sauna heater requiring 6 kW, 400V 3/N~, 10A power supply.

A compatible electric heater and professional electrical connection are required for operation.

The Hele Nano uses a natural ventilation system designed to maintain comfortable airflow during sauna sessions.

Proper ventilation helps regulate temperature, improves air quality, and removes excess humidity after use.

Yes. The sauna floor includes integrated water channels that direct water toward a drainage outlet with an odor trap.

For proper drainage, the sauna should be installed on a level base using the adjustable legs, and a slight slope (about 1%) should be maintained toward the designated drainage direction.
