Helo Vienna LED 4.5 kW, 6 kW & 8 kW Electric Sauna Heaters with Built-in Controls

Helo Vienna LED 4.5 kW, 6 kW & 8 kW Electric Sauna Heaters with Built-in Controls

Ever thought of combining an electric sauna heater and sauna lighting into one invention? That’s what Helo, the world’s oldest sauna heater brand, decided to do: wall-mounted Helo Vienna LED with built-in controls brings you a warm 2700K glow through its honeycomb-patterned front and side panels.

The light turns on automatically when the heater is switched on (and can’t be operated separately), staying on as your sauna heats and as you enjoy your sauna session(s); for 3 continuous hours as the maximum time.

The light illuminates the entire heater body. Stone arrangement won’t affect how the light glows, as it lives between the inner frame and outer casing, ensuring even and consistent light every time. The light isn’t static, but instead, rises from the bottom to the top, making the sauna feel calmer and more inviting.

Vienna LED’s innovativeness doesn’t stop there, since the 6 kW model has an adjustable stone capacity thanks to two different levels. If you use the shallower one, allowing for 26 lbs of stones, the sauna heats even faster, while the deeper level allows for 44 lbs of stones and brings you more löyly (steam) that’s also more long-lasting.

The control knobs are reversible, which means they can be positioned either on the left or right side of the heater during installation to fit your sauna layout perfectly.

Unlike all other electric sauna heaters in our selection, these Helo models don’t include a delay timer.

Vienna LED sauna heaters are designed to turn heads, made in Finland, and built to last.
