Good to know

Why choose inup Frameless?

Inup emphasizes a particularly high share of A-radiation – for deep-reaching warmth that penetrates far beneath the skin. At the same time, the frameless design enables aesthetic integration into any refined sauna environment.

What makes full spectrum heaters different from other infrared heaters?

Full-spectrum heaters cover all three infrared ranges (IR-A, IR-B, and IR-C), generating deeply effective warmth. Compared to conventional ceramic heaters, they offer a noticeably faster and more intense heat sensation.

Do I need a special control system?

For maximum comfort, we recommend our inup touch control , which allows you to individually adjust the temperature and runtime. Alternatively, the heater can also be operated using a simple switch.

How are the Frameless infrared heaters installed?

The heaters are installed flush into the sauna wall without any visible screws. Thanks to their frameless design, they align perfectly with the wood and blend seamlessly into any interior.

Can I use an infrared heater and sauna stove at the same time?

Yes, both systems can be used in a combo sauna – depending on your mood and preferences. The infrared and conventional heating systems operate independently, giving you maximum flexibility for every sauna session.
