Electric vs wood-fired
This cabin can be heated two ways. Pick the ritual that suits you:
- Electric (Harvia Cilindro). One-touch convenience with precise temperature control and optional Wi-Fi scheduling. Ready to bathe in 30-45 minutes, with no fuel or flue to manage.
- Wood-fired (Harvia Linear 18). The traditional experience, with the crackle and aroma of a real fire and a deep, enveloping heat. Needs no power supply, so it's ideal for off-grid gardens.
Both reach full löyly temperature. The choice comes down to convenience versus authenticity.
