Energy saving

Warms you, not the room

Stoov warms your body directly with infrared heat, using a fraction of the energy it takes to heat a whole room, so you feel warm faster and save on energy bills.

Good for body and mind

The wellbeing benefits of infrared

Infrared warmth helps soothe tense muscles, making it easier to unwind, so every Stoov moment feels as good as it feels warm.

One battery, two jobs

Doubles as a power bank

The Smartlabel in your Stoov doubles as a power bank, letting you charge your phone on the go, so you stay warm and connected wherever you are.

FAQ's

How does Stoov heating work?

Stoov uses in house designed far infrared technology that warms you directly instead of heating the air around you. It’s efficient, safe, and gives you a cosy warmth that feels natural.

How long does the battery last?

Depending on the product, the battery type and heat setting, a Stoov keeps you warm for up to 14 hours on a single charge. Perfect for a full workday, a long evening on the couch or a night of camping.

Can I wash the cover?

Absolutely. All Stoov covers are removable and machine-washable. Just take out the heating element and battery, and wash the fabric according to the care label.

Where can I use my Stoov?

Anywhere you want. Stoov products are cordless and portable, so you can enjoy warmth at home, in your garden, in the office, on the terrace or even while camping. Warmth, your way.
