Description

What is the Harvia Virta Combi 9 kW electric sauna heater and steamer (HL90SA)?

The Harvia Virta Combi 9 kW (HL90SA, Harvia item HL9U1SAUL) is a floor-standing electric sauna heater with a built-in 2.1 kW steamer, in a black-painted steel casing, for sauna rooms of 177–494 cu ft. It heats the sauna the usual way or with its steamer, whose 1.3 gal (5 L) tank gives about 2 hours of steam, and liquid fragrances or fragrance bags can be used in the steamer. It runs on 240 V single-phase power on two supply circuits, holds up to 110 lb (50 kg) of 2–4" stones, and needs a separate Harvia Combi control.

Which control does the Harvia Virta Combi 9 kW need?

The Harvia Virta Combi 9 kW needs a Harvia Combi control, which runs the heater and the steamer: a plain Xenio or Fenix cannot run the steamer. Use the Harvia Xenio Combi CX30C-U1-XW or the Harvia Fenix Combi FX30C-U1-XC, both sold separately. The Xenio Combi can be set from 104 to 194°F (40–90°C) and from 20 to 80% humidity; it runs the heater for up to 1 hour per start and can delay a start by up to 12 hours, and the CX30C-U1-XW has Wi-Fi for Harvia's MyHarvia app.

Specifications

Does the Harvia Virta Combi 9 kW fit my sauna?

The Harvia Virta Combi 9 kW heats sauna rooms of 177–494 cu ft (5–14 m³) with 28–79 sq ft of floor, according to Harvia's Virta Combi manual 26092023/Y05-0898. Harvia's sizing rule adds 1.2 m³ for every square meter of uninsulated brick, glass block, glass, concrete or tile wall, about 3.9 cu ft per sq ft, and a glass door counts: Harvia's example is a 10 m³ room with a glass door, which needs the output of a 12 m³ room. The Virta manual multiplies the volume of a log sauna by 1.5.

Installation

How is the Harvia Virta Combi 9 kW installed?

The Harvia Virta Combi 9 kW stands on the sauna floor on adjustable legs, which level it. Harvia's manual asks for a heat-resistant floor covering where the heater stands, because hot pieces of stone can damage floor coverings. Harvia allows one electric heater per sauna room unless several heaters share one control unit. The heater is hardwired: Harvia's manual allows no plug or receptacle in the sauna room, and only an authorized, licensed electrician may connect it. The control's power unit goes on a wall outside the sauna room, in a dry place above 32°F (0°C), and the WX248 temperature sensor that comes with the heater mounts above it. Your licensed electrician sizes the breaker and wire from the manual that ships with the heater and your local code. Harvia's installation manual, under Documents, gives the exact sensor, wiring and vent positions.

Harvia Virta Combi 9 kW safety distances

Keep at least these distances between the Harvia Virta Combi 9 kW and walls, benches and anything that can burn.

Harvia Virta Combi 9 kW minimum distances (Harvia Virta Combi manual 26092023/Y05-0898)
Heater to side walls, back wall and benches	2" (50 mm)
Top of the heater to the ceiling	42" (1,060 mm)
Heater fence (required, not in the box)	Harvia's manual calls a softwood heater fence necessary for safety: at least 2" (50 mm) from the heater on every side and at least 28" (711 mm) high, with its top at least 1" below the top of the heater and never above the rock line
Sauna room height	At least 75" (1,900 mm); ceiling no higher than 7 ft 6 in (2,300 mm)

Does the sauna room need ventilation?

Yes. Harvia's Virta Combi manual calls for adjustable vents that change the air five times an hour: a supply vent low down beside the heater and an exhaust vent on the opposite wall. The manual gives their positions.

Does the Harvia Virta Combi 9 kW need a water line?

Only for automatic filling. The Harvia Virta Combi 9 kW's steamer can fill its 1.3 gal (5 L) tank automatically from a cold-water supply line with a shut-off valve and a vacuum breaker, at 22–58 psi (150–400 kPa), and Harvia recommends a floor drain. Without a water line, the tank is filled by hand, after a jumper in the heater is removed.

Frequently Asked Questions

What comes with the Harvia Virta Combi 9 kW heater, and what else does it need to run?

The Harvia Virta Combi 9 kW ships as the heater, the built-in steamer with its 1.3 gal (5 L) tank, its WX248 temperature sensor, a fastening kit, CAUTION and WARNING signs for the sauna and Harvia's installation manual. It does not run on its own: it needs a Harvia control, the Xenio Combi CX30C-U1-XW or the Fenix Combi FX30C-U1-XC, sold separately. It also needs 2–4 in split-face stones (up to 110 lb; three 44 lb boxes of Harvia AC3000 cover it), a circuit installed by a licensed electrician and the heater fence Harvia's manual requires.

Which control does the Harvia Virta Combi 9 kW need?

The Harvia Virta Combi 9 kW needs a Harvia Combi control, because a plain Xenio or Fenix cannot run its steamer: the Xenio Combi CX30C-U1-XW or the Fenix Combi FX30C-U1-XC. The Xenio Combi can be set from 104 to 194°F (40–90°C) and from 20 to 80% humidity, runs the heater for up to 1 hour per start and can delay a start by up to 12 hours; the CX30C-U1-XW has Wi-Fi for Harvia's MyHarvia app. The control's power unit goes on a wall outside the sauna room.

What size sauna is the Harvia Virta Combi 9 kW for?

The Harvia Virta Combi 9 kW is for sauna rooms of 177–494 cu ft (5–14 m³), with 28–79 sq ft of floor, according to Harvia's Virta Combi manual. Harvia's sizing rule adds about 3.9 cu ft for every sq ft of uninsulated brick, glass, concrete or tile wall, counting a glass door (1.2 m³ per m²), and the Virta manual multiplies a log sauna's volume by 1.5. The room must be at least 75 in tall, with a ceiling no higher than 7 ft 6 in. Larger rooms, up to 635 cu ft, suit the Virta Combi 10.5 kW.

What electrical supply does the Harvia Virta Combi 9 kW need?

The Harvia Virta Combi 9 kW runs on 240 V single-phase power wired as two supply circuits: Harvia's Virta Combi manual lists 25 amps per circuit. The heater is hardwired from the control's power unit, with no plug or receptacle in the sauna room, and Harvia's manual says only an authorized, licensed electrician may connect it. Your licensed electrician sizes the breaker and wire from the manual that ships with the heater and your local code.

How is the Harvia Virta Combi 9 kW installed?

The Harvia Virta Combi 9 kW stands on the sauna floor on adjustable legs, on a heat-resistant floor covering, and Harvia allows one electric heater per sauna room. Keep it at least 2 in from the walls and benches and 42 in below the ceiling, and build the softwood heater fence Harvia's manual requires, at least 2 in from the heater and 28 in high, with its top below the top of the heater. The control's power unit goes outside the sauna room and the WX248 sensor above the heater. A licensed electrician hardwires it, following the exact positions in Harvia's installation manual. Automatic tank filling needs a cold-water line with a shut-off valve and a vacuum breaker; without one, the tank is filled by hand.

How long does the Harvia Virta Combi 9 kW take to heat up, and how is its steamer used?

The Harvia Virta Combi 9 kW takes about an hour to bring a properly insulated sauna to bathing temperature when the room suits its output, according to Harvia's Virta Combi manual; Harvia gives about 149–167°F as a suitable temperature. The steamer's 1.3 gal (5 L) tank runs for about 2 hours; fill it with clean household water while the heater is cold, before every use. Liquid fragrances go in the steamer's stone cups and fragrance bags on its grating. After a steam session, let the sauna dry out fully, with the ventilation open.

How do you maintain the Harvia Virta Combi 9 kW's steamer and stones?

The Harvia Virta Combi 9 kW holds up to 110 lb (50 kg) of 2–4 in angular split-face stones; Harvia names peridotite, olivine-dolerite, olivine and vulcanite, and three 44 lb boxes of Harvia AC3000 cover it. Place the stones sparsely, rearrange them at least once a year and replace crumbled ones, so no heating element shows. Drain the steamer tank after every use, once the water has cooled, descale it with a household descaler, and wash the stone cups. Use only clean household water; chlorinated water and seawater are forbidden.

What problems do Harvia Virta Combi 9 kW owners run into, and how are they avoided?

Most problems Harvia's Virta Combi manual covers for the Harvia Virta Combi 9 kW trace back to the control settings, the stones or the installation. A heater that will not heat needs its breakers, cable, the temperature set on the control and the overheat protectors checked. Slow heating means checking that every element glows and that the output and ventilation suit the room. Panels that darken quickly mean the safety distances are too short or elements show through the stones. A smell during the first uses is normal, and occasional bangs are stones cracking in the heat. On the steamer, fill the tank only when the heater is cold and drain it after use.

Who makes the Harvia Virta Combi 9 kW, and what is it made of?

The Harvia Virta Combi 9 kW is made by Harvia, the Finnish sauna manufacturer. It has a black-painted steel casing on adjustable legs. Its steamer sits inside the same casing, with a 1.3 gal (5 L) water tank. The heater is ETL Listed and conforms to UL 875. Harvia's Virta Combi manual gives it as 16 by 16 by 33 in (width, depth, height), weighing 63.9 lb without stones.

What warranty does the Harvia Virta Combi 9 kW have?

Harvia's manufacturer warranty covers the Harvia Virta Combi 9 kW for 2 years, and Harvia adds a third year when the heater is registered on harvia.com within 30 days of purchase. The control has its own 2-year manufacturer warranty, with no registration year. Sauna stones are not covered, and Harvia's terms require the heater to be installed by a qualified electrician, with proof of the installation. Harvia US Inc. is the warrantor in North America; Topture is an authorized Harvia retailer and assists with troubleshooting and warranty coordination.

How does the Harvia Virta Combi 9 kW compare with the plain Virta 9 kW and the Virta Combi 10.5 kW?

The Harvia Virta Combi 9 kW and the plain Virta 9 kW heat the same rooms, 177–494 cu ft. The Combi adds a 2.1 kW steamer with a 1.3 gal tank for humid, softer sessions, is 16 in deep instead of 13, runs on two 25 amp circuits at 240 V and needs a Combi control. The Virta Combi 10.5 kW covers rooms up to 635 cu ft in a 19 in deep body, with 154 lb of stones and a 208 V three-phase model.

Where can you buy the Harvia Virta Combi 9 kW from an authorized dealer?

Topture is an authorized Harvia retailer and sells the Harvia Virta Combi 9 kW, with the Xenio Combi and Fenix Combi controls, the stones and the HL3M safety rail separately, each one an option chosen for this heater. Topture adds Lifetime Expert Support, help with troubleshooting and warranty coordination, free shipping on orders over $200 within the continental US, financing through Shop Pay Installments at checkout, and a 30-day return window.

What does a Harvia Virta Combi 9 kW cost in total, delivered?

The delivered cost of a Harvia Virta Combi 9 kW from Topture is the heater price plus the parts it needs to run: a Harvia Combi control and three 44 lb boxes of stones. Topture has free shipping on orders over $200 within the continental US, so a Virta Combi 9 kW order ships free there. Budget separately for a licensed electrician and the heater fence. Compare delivered totals, because some listings price the heater without its control or stones. Financing is available through Shop Pay Installments at checkout.

General Topture Questions

Where are you located, and where do you ship from?

Orders ship from manufacturer and distributor warehouses in the U.S. and Canada, and some products ship directly from the manufacturer in Europe. Each product page shows its estimated delivery time.

How much is shipping?

Orders over $200 ship free within the continental United States. Orders under $200 carry a small shipping fee.

Two exceptions: SaunaLife and ThermaSol products carry a freight charge at any order value, and sauna stones ordered without a heater ship at $60 per box because of their weight.

Every charge is shown at checkout before you pay.

Do you provide financing?

Absolutely! To view your financing offer, simply select Shop Pay Installments as your payment method at Step 3 of checkout.

You'll need to enter a debit card to receive your offer, but don’t worry—you can still back out before completing the purchase.

How long will it take for my items to arrive?

If your order is in stock, most orders ship within 2–7 business days of purchase. Transit time then depends on the distance from the warehouse and, for freight, on booking a delivery appointment.

For custom, pre-order or made-to-order items, the estimated delivery time frame is listed on the product page. Delivery dates are estimates, so please don't book installation labor until your order has arrived and been inspected.

What happens after I place my order?

As soon as you place your order, you'll receive a confirmation email with your order details—be sure to keep it for your records. Once your order ships, you'll receive another email with tracking information.

For freight deliveries, the carrier will call or text you to schedule an appointment once the shipment reaches their local terminal. Someone needs to be there to inspect the shipment and sign for it. Smaller parcels arrive by UPS or FedEx without an appointment.

Is there a warranty?

Yes. Products purchased through Topture include the applicable manufacturer’s warranty, subject to the manufacturer’s terms. You’ll find the warranty details for each product under the "Warranty" tab on its product page, and we help with troubleshooting and warranty coordination if an issue comes up.
