Do I need a dedicated circuit?

No. A standard 10 A power point is enough; the Helsi™ One draws 1,800 W, about 7.5 A.

How much space do I need?

Pulled out, 200 × 80 cm of floor. Stored, it stands upright at 100 × 76.5 × 48 cm.

Does it work in a rental?

Nothing is mounted and nothing is connected except to the socket. When you move, you take it with you.

How long does it take to heat up?

15 to 20 minutes, depending on the level and the room temperature.

Can I use red light without heat?

Yes, the controller has three modes: infrared, red light or both.

How is it different from a sauna blanket?

A blanket lies directly on your body. In the Helsi™ One you lie under two rigid domes, with red-light LEDs.

How is it different from an infrared cabin?

In a cabin you sit, your head is in the heat, and it stays in the room. In the Helsi™ One you lie down, your head stays out, and afterwards you fold it away.

Measured at 0.1 mG, thanks to shielding mesh in the domes.

Let it cool, wipe the mat and pillow with a mild cleaner and dry them with a clean towel.

What is a sauna dome?

A dome sauna you lie in: two domes close over your body, your head stays out. The Helsi™ One Sauna Dome is a portable infrared sauna of this type, with red-light LEDs.

Can I use it outdoors?

No, indoors only, on a level, dry floor near a power point.

Comparison

Cabin, tent, blanket or dome?

There are four ways to get infrared heat at home. They differ in whether you sit or lie, where your head is, and what stays in the room after the session.

Typical manufacturer figures for each build type, October 2026. If you have a fixed spot for a cabin, a cabin serves you well. The Helsi™ One is for rooms where no cabin should stand.

Fits an apartment

Between sessions the Helsi™ One stands upright, 100 × 76.5 × 48 cm, about the footprint of a side table. For a session you roll it out on its rubber wheels and pull both domes over the 200 × 80 cm mat. It takes about two minutes.
No dedicated circuit: a standard 10 A power point is enough, the Helsi™ One draws 1,800 W, about 7.5 A. Use extension cords only if they are rated for the full load.
No water, no steam in the room. Air the room briefly after a session and wipe the mat.
Nothing is fixed to a wall or ceiling or permanently connected. When you move, it moves with you. Indoors only, on a level, dry floor.
