Harvia Cilindro 8 kW Electric Sauna Heater The Harvia Cilindro 8 kW Electric Sauna Heater is a sleek, pillar-style electric heater designed for sauna rooms from 141 to 423 cubic feet (4–12 m³). Its partially open front casing allows heat to radiate efficiently from a large stone surface while keeping a compact footprint — ideal for modern, space-conscious sauna layouts.
With its impressive 198 lb (90 kg) stone capacity, the Cilindro creates soft, consistent heat and lets you tailor your steam experience. Pour water into the center for a gentler, more enveloping steam, or onto the top for an invigorating burst. Its flexible design allows for freestanding installation, mounting against a wall or in a corner, or embedding into a lower bench for a clean, integrated look.
This model is Wi-Fi compatible and requires the Harvia Xenio CX45-U1-U3-XW digital control unit (sold separately) for operation. The external, splash-proof control panel can be mounted inside or outside your sauna and allows you to manage your sauna remotely through the MyHarvia mobile app.
⚠️ Control unit and sauna stones sold separately. To operate this heater, you must purchase the Harvia Xenio CX45-U1-U3-XW controller.
