Harvia Cilindro PC90: a 9 kW stone pillar heater with built in controls for saunas up to 494 cubic feet
The Harvia Cilindro PC90 is a 9 kW electric sauna heater shaped like a tall round pillar that stands on the floor, with time and temperature knobs built into its base. It heats saunas from 141 to 494 cubic feet. It goes against a wall or in a corner, shows its stones through the open front half of the casing, and measures 14 inches wide, 13 inches deep, and 40 inches tall. It weighs 37.5 pounds before stones. The grate holds 200 pounds of stones directly against the heating elements for soft heat and lasting steam. Pour water on the side of the pillar for gentle steam, or on top for a sharper burst.
You get the heater and its manual, ready for a 240 volt circuit. The built in knobs mean there is no wall control to buy or wire. Sauna stones are sold separately, so add the 5 boxes it needs on the page. A floor embedding flange, a safety rail, and a bucket and ladle set are optional. Prefer a digital wall control with WiFi? The Harvia Cilindro PC90E sauna heater pairs with the Xenio. The Harvia Cilindro PC90 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What size sauna room does the Cilindro PC90 support?
The 9kW PC90 is rated for sauna rooms from 141 to 494 adjusted cubic feet. Measure your room’s interior volume and confirm it lands inside that range before ordering; the installation and operation manual linked on this page explains how to account for your specific room construction when sizing the heater.
Do I need a separate control unit to run it?
No. This version of the PC90 has built-in controls, so temperature and operation are managed right at the heater – there is no external control panel to buy, mount, or wire. The electrical hookup of the heater itself should still be handled by a licensed electrician following the installation manual and local codes.
Are the sauna stones included, and how many do I need?
The box includes the heater and its installation and operation manual, and the stones ship as their own boxes: this heater requires a minimum of 200 lbs, which is the 5-box option under Required Stones on this page – select it with your order. Harvia also suggests adding one extra box so you can hand-pick the best-fitting stones; additional freight charges apply to the extra box.
Can you pour water on an electric sauna heater like this?
Yes – that is the point of the stone pillar design. With 200 lbs of stones behind the grate-like outer shell, you can throw water on the side of the heater for softer steam or straight onto the top of the stone pillar for a sharper burst. That adjustable steam is a signature of Harvia’s Cilindro pillar heaters.
What are the electrical requirements?
The specification table lists 240V, single-phase service with a nominal draw of 37.5 amps. Have a licensed electrician plan and connect the circuit according to the installation manual on this page and your local electrical codes – breaker and wire sizing depend on your specific installation and are covered there, not here.
Where can it be installed in the sauna?
The PC90 is a floor-standing steel pillar heater designed for side-wall or corner placement in the sauna room. Follow the clearance and mounting details in the Harvia Cilindro installation manual linked on this page, and confirm the layout meets your local building codes before finalizing the heater’s position.
What's included in the box, and what warranty do you get?
You receive the sauna heater and the installation and operation manual, backed by Harvia’s 2-year consumer-use warranty. The heater is designed, engineered, and made in Finland, with stainless steel construction, direct rock-to-heating-element contact, and industrial-grade serviceable elements. Remember to select the required stone boxes with your order on this page to complete the setup.
