Harvia Club Sauna Heaters

The Club: Harvia's Commercial Floor Heater

The Club is the heater you buy when a home heater isn't enough. It's Harvia's commercial-grade stainless steel floor unit, built for big rooms and the kind of use a residential heater isn't designed for — back-to-back sessions all day, every day, in a gym, spa, condo amenity room, or oversized residential build. Stainless body, floor-standing, and rated from 388 all the way up to 989 cubic feet. If your room is genuinely large or your sauna runs hard, this is the line.

It comes in three wattages — 10.5kW, 12.5kW, and 15kW — holds 132 lbs of stones, and tops out at 194°F like the rest of the Harvia electric range. The stainless construction matters in a commercial setting: it stands up to constant heat cycling and the humidity of a heavily-used room better than painted steel. This collection covers all three Club wattages plus the package versions at 10kW and 12kW that bundle the digital controller, WiFi, and stones.

How to Size and Spec a Club

Match the wattage to a large room

The Club starts where the residential lines tap out. The 10.5kW handles the smaller end of its range, the 12.5kW the middle, and the 15kW reaches up to 989 cu ft — large commercial rooms or oversized cabins. Because commercial rooms see constant door traffic and bodies coming and going, lean toward sizing up rather than down; a heater that has to recover from a dozen door openings an hour needs headroom a home unit doesn't. If your room is actually under about 400 cu ft, you may not need a Club at all — the residential lines cover that range at lower cost. The 12.5kW also appears in our 12kW sauna heater collection if you want to compare it against other heaters at that wattage.

Plan the electrical — and consider three-phase

Club heaters run on 208V or 240V, and at these wattages three-phase power is often available and frequently the better choice for a commercial install. A 10.5kW single-phase heater pulls about 43.75 amps and lands on a 50A breaker; the 12.5kW and 15kW climb from there and are common candidates for three-phase wiring to balance the load. These are not casual hookups — they need a dedicated circuit and, in a commercial building, often a panel that's spec'd for the draw. Always consult a licensed electrician before any electrical work; requirements vary by local code and jurisdiction and the figures here are general reference only. Our sauna electrical requirements guide covers the rough-in, and for a commercial job your electrician should confirm phase, breaker, and wire gauge for the specific install.

Controls and WiFi for a busy room

The Club pairs with a Harvia digital controller, and the package versions include WiFi. For a commercial room, remote control earns its keep — staff can preheat before opening, set schedules around peak hours, and monitor the room without standing at the door. You'll find the WiFi-capable Harvia heaters grouped in our WiFi sauna heater collection. In a high-use setting, scheduled preheats also cut the dead time customers spend waiting for the room to come up to temperature.

Stones and What to Order Alongside

A Club holds 132 lbs of stones, and Harvia specs olivine diabase. In a commercial room that's running constantly, proper sauna stones matter even more than at home — generic landscape rock cracks under relentless heat cycling and you'll be picking shards out of the basket. Fill to the rated weight and plan to inspect and refresh the stones periodically in a high-use install, since stones do break down faster under the constant cycling a commercial room puts them through. Stock up in our sauna rocks collection. The simplest way to order a Club is the bundled route: our Harvia electric heater packages include 10kW and 12kW Club configurations with the digital controller, WiFi, and stones already matched, so the electrician and the installer both get parts that are spec'd to work together.

One more sizing note worth flagging for commercial buyers: the 12.5kW and 15kW Club units pull serious current, so the breaker, wire gauge, and panel capacity all need to be confirmed for the room before you commit. It's the kind of detail that's cheap to get right up front and expensive to fix after the walls are closed.

Club vs. the Residential Harvia Lines

The Club's nearest sibling on paper is the Virta, and people mix them up because both are floor-standing. The difference is what they're built for. The Harvia Virta is the premium residential floor heater — 6 to 10.5kW, 150 lbs of stones, classic Finnish feel for a home sauna. The Club is the commercial unit: stainless, higher wattages, built for the abuse of an all-day install. If your room is a home sauna, even a large one, the Virta is usually the right call and costs less. If it's a gym, spa, hotel, or condo amenity room, you want the Club's stainless body and commercial wattages. For a vertical look with even more stone mass, the Harvia Cilindro column is another option in larger residential rooms, and the entry-level Harvia KIP covers small home rooms at the opposite end of the range. The full lineup is laid out on the Harvia electric heater hub.

When the Club Is the Right Heater

Buy a Club when the room is large, the use is heavy, or both. Commercial operators need a heater that survives constant cycling and recovers fast between guests, and the Club is Harvia's answer to that — the same reliability that makes us recommend Harvia generally, built into a stainless commercial body. We're an authorized Harvia dealer, so the warranty applies and our team can help spec the right wattage and phase for your room. For a commercial job especially, message us before you order — getting the sizing and electrical right up front saves a far more expensive correction later. And if you're weighing the whole field, the full sauna heater catalog puts the Club next to every other commercial-capable heater we carry.
