Harvia Cilindro 20 Wood-Fired Sauna Heater

The Harvia Cilindro 20 Classic Wood-Fired Sauna Heater is a contemporary pillar-style heater designed to deliver authentic Finnish sauna warmth in medium-sized sauna rooms ranging from 8–20 m³ (282–706 cu. ft.). Its tall, sculptural form and stainless-steel exterior bring a modern look to the sauna while preserving the character of a traditional wood-fired experience.

With a generous 120 kg (265 lb) stone capacity, the Cilindro 20 produces soft, plentiful steam that lingers, creating a comfortable and immersive sauna environment. A dedicated ventilation duct system accelerates heat-up times and supports efficient combustion, helping the stove reach optimal temperatures quickly and evenly.

A cast-iron framed glass door allows the natural glow of the fire to remain visible, adding warmth and ambiance to the sauna. For installation flexibility, the door’s opening direction can be adjusted to suit different layouts.

Built for long-term reliability, the Cilindro 20 incorporates advanced air control channels and replaceable firebox plates, which help protect key components and extend the stove’s service life. The heater is CE certified, ensuring compliance with European safety and quality standards, and is proudly manufactured in Finland.

Please note: Chimney pipe not included. Sauna stones sold separately.
