The Harvia Cilindro PC90 is a 9 kW floor- or wall-mounted electric sauna heater for rooms of 141–494 adjusted cubic feet running on 240VAC 1PH. It takes 200 lb of 5-10cm sauna stones (sold separately). Controls are built into the heater, so no separate control unit is required.
The Harvia Cilindro is a vertical pillar heater built around an unusually large stone mass held in an open, grate-like stainless steel cage. Because the stones are exposed on every side, the bather controls the steam: water thrown against the side of the column produces a soft, rolling löyly, while water poured straight down onto the top of the pillar produces the sharp, immediate burst that Finnish bathers call a hard steam.

- Direct rock-to-heating element contact
- Industrial grade, serviceable heating elements
- Grate-style open stone cage lets you tune steam character by where you pour
- Direct rock-to-element contact for a softer, longer-lasting löyly

Hardwired on a dedicated circuit. Not a plug-in appliance. Who Installs It
A licensed electrician sizes the breaker and conductors from the nameplate and installation manual under the current NEC. Circuits
Fused as 2x30A, so this model needs two circuits, not one.
The Harvia Cilindro PC90 is rated for 141–494 adjusted cubic feet.
Adjusted cubic feet = width × depth × height in feet, plus 45 cu ft for every square foot of glass, tile, concrete or stone, plus 15 cu ft for every square foot of exposed log wall. A 6 × 7 ft room with a 7 ft ceiling is 294 raw cu ft — add a full-glass door and it becomes 834. Always size to the adjusted number.

- Mount to the clearances given in the installation manual. The temperature sensor goes on the wall above the heater, at the height the manual specifies.
- Load the stones loosely by hand, largest at the bottom, so air moves freely between them. Never run the heater with an empty or tightly packed stone space.
- Pour small ladlefuls of clean water onto the hot stones only — never onto the body, elements or controls. Mix any scented oil into the bucket first.
- Re-stack the stones once a year and replace any that have cracked or crumbled.
- Stones ship separately on their own freight because of the weight.
Does the Harvia Cilindro PC90 include a control unit?
Yes. The thermostat and timer are built into the heater body, so there is nothing else to buy to run it. The trade-off is that you cannot start it from outside the room or from a phone.
Can the Harvia Cilindro PC90 be plugged into a normal outlet?
No. It is a hardwired appliance on its own dedicated circuit, rated at 37.5 A. A licensed electrician sizes the breaker and conductors from the nameplate and installation manual.
How long does the Harvia Cilindro PC90 take to heat up?
Harvia does not publish a figure. A correctly sized, well-insulated room is usually ready in 30 to 60 minutes. Consistently longer than an hour normally means the heater is undersized for the room's adjusted cubic feet.
