Harvia Virta Combi HL90SA: a 9 kW sauna heater and steamer for rooms up to 494 cubic feet
The Harvia Virta Combi HL90SA combines a 9 kW electric sauna heater with a steamer, giving you a dry sauna, a soft steam bath, or a scented bath with herbs or fragrance in the built-in cups. It heats sauna rooms from 177 to 494 cubic feet. The floor standing black steel column goes against a side wall or in a corner and measures 16 inches wide, 16 inches deep, and 33 inches tall and weighs 64 pounds empty. Its open top holds 100 pounds of stones on serviceable stainless steel heating elements.
You get the heater, the water reservoir, and the manual. The 5 liter reservoir fills by hand or automatically from a water line. It needs the Harvia Xenio Combi wall control to run, and you add that on the page. Sauna stones are sold separately, so add the 3 boxes it needs on the page. A wood safety rail and a bucket and ladle set are optional. Smaller sauna? The Harvia Virta Combi HL80SA is the 8 kW version. The Harvia Virta Combi HL90SA ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
Can this heater turn my sauna into a steam spa?
Yes — the Virta Combi HL90SA is a 9kW electric sauna heater and steamer in one, built for soft, humid steam and spa-style sessions. It has designated places for fragrance liquids and bags, so you can choose between a traditional sauna, a steam sauna, a herbal sauna, or a fragrance sauna in the same room.
What room size is the 9kW Combi rated for?
It is rated for sauna rooms from 177 to 494 adjusted cubic feet, per both the features list and the specifications table. Measure your room and confirm the adjusted-volume figure with the installation and operation manual linked on this page, particularly if the space is near the top of that range.
Is there a safety rail for this heater?
Yes — the Harvia HL3M wood safety rail fits this model, and it is offered right on this page under the Safety Rail option, so you can add it to your order along with the heater. For mounting and the required clearances, follow the installation documentation linked on this page.
How many stones does the heater take, and are they in the box?
The heater needs a minimum of 100 pounds of sauna stones, which you order as the three stone boxes in the Required Stones selector on this page — add them with your order. Harvia recommends an extra box so you can choose the best-fitting stones, since each natural stone is unique in shape and size (additional freight applies).
What are the electrical specs?
The specifications list 240V single-phase power at a nominal 25 amps across two circuits. As with any electric sauna heater, the hookup must be done by a licensed electrician following the installation and operation manual and your local electrical codes, which determine the exact breaker and wiring requirements.
Does the steamer refill itself?
The Combi’s 5-liter water reservoir supports both automatic and manual water filling, so it can be set up for automatic refills or topped up by hand. The reservoir is included with the heater. Setup details for either filling method are in the Harvia Virta Combi Auto manual linked on this page.
What controls does it use?
The heater requires a Xenio digital sauna control — the listed control for this model is a Xenio Combi-series unit with WiFi, available in the Required: Sauna Heater Controls selector on this page so it ships with your order. If you’re comparing steam-capable heaters, the other Harvia Virta Combi models are grouped in the same category.
