Shipping & Delivery
Shipping & Delivery
Every Harvia heater and stove ships free to the contiguous 48. What changes across the range is not the cost to you but how it arrives: electric heaters come by parcel and need nobody home, while wood-burning stoves come palletized by freight, by appointment, to the curb. Call (888) 500-5675 if you want the delivery method for your exact model confirmed before you order.
Electric heaters ship by parcel. Wall-mounted and pillar heaters run roughly 29 to 55 pounds, so they travel as insured ground parcel. No delivery appointment, no liftgate, no waiting in. These are the models that ship free to the lower 48.
Wood-burning stoves ship by freight. A wood stove can weigh several hundred pounds before you add stone, so it moves palletized on an LTL carrier. Freight is included to the contiguous 48. What a pallet changes is the handling: a delivery appointment, a signature, and curbside drop rather than a carrier leaving it at the door.
Sauna stones ship separately and they are heavy. A heater takes anywhere from one box to thirteen at roughly 44 pounds a box. That weight is why stones are quoted with your order rather than folded into a headline price.
Scheduling your delivery. Parcel shipments need nobody home. For freight, the carrier calls to arrange an appointment window and someone must be there to sign. Curbside is the standard: the driver will not bring a pallet inside or up steps, so arrange help for a heavy stove.
Where we ship. The contiguous 48 states. Alaska, Hawaii, Puerto Rico and Canada are quoted case by case, so contact us before ordering.
Inspect before you sign. Check the carton or pallet for damage while the driver is still there, and note any damage on the delivery receipt at the time of signing. Then contact us the same day. A clean signature with no damage noted makes a freight claim much harder to win, and this one habit is what decides most claims.
Lead times. Harvia stock for this market moves through a US distributor, so most orders ship promptly. Some part numbers are supplied from Finland and take longer. We confirm the position for your specific model when you order rather than publishing an average that would be wrong for half the range.
Questions before you order? Ten minutes on the phone confirming freight, lead time and what else has to be on the same pallet is cheaper than a surprise after you have paid.
Warranty
Warranty
Harvia covers its sauna heaters and wood-burning stoves against defects in materials and workmanship under normal use. Coverage runs from your date of purchase, so keep your receipt. Harvia US Inc. is the warrantor for North America.
Coverage periods. Residential family use: 2 years on electric heaters, controls and steam generators including the heating elements, and 2 years on wood-burning stoves. Commercial use: 2 years on electric heaters, controls and electronics but 6 months on heating elements, and 6 months on wood-burning stoves.
Register within 30 days and Harvia adds a third year. Registration is free and needs the model, serial number and purchase date. We send you the link and your serial number with your order, so you do not have to go looking for it. Electric heaters in residential use only. Almost no retailer mentions it, and it is worth a full extra year.
What is covered. Defects in manufacture and materials. Harvia will repair the product or supply replacement parts through the importer. Replacing a part does not extend the original period.
What is not. Normal wear, improper installation, poor maintenance, failure to follow the instructions, alterations and improper use. Sauna stones are a consumable and are not covered, and stones Harvia does not specify for your model can void cover.
Professional installation is a condition. Harvia requires that the unit is installed and wired by a licensed electrician and that proof of professional installation can be presented with a claim. Keep your installer's invoice with your receipt. A heater wired by the owner is outside the warranty.
Transport damage has a seven day limit. Harvia requires that you check the product for transport or storage damage on receipt, and that any damage found is reported to the seller or the carrier immediately and no later than seven days after delivery. We ask you to call us the same day because a claim is far easier to win with the damage noted on the delivery receipt, but seven days is the outside limit in Harvia’s own terms.
Changing how you use it ends the cover. Harvia states that the warranty period expires immediately if the primary intended use changes during the period, in either direction. Moving a heater from a family sauna into a gym, a rental or any other commercial setting ends the residential cover rather than converting it. Tell us before you order if the room will be used commercially, so we can quote it on the right terms from the start.
A callout for a fault that is not covered can be charged. If the defect turns out to fall outside the warranty, Harvia is entitled to charge for the work of finding it, including labour, travel and shipping at actual cost. Call us first and we will work through the symptoms with you before anything is booked, which is usually enough to tell whether it is a warranty fault, an installation issue or a stone problem.
How to make a claim. Call (888) 500-5675 or email sales@recoveryroomdirect.com with your order number, model and serial number, and a description of the fault. Photographs help. We open the claim with Harvia US on your behalf.
Return Policy
Return Policy
If a Harvia heater or stove is not right, you have 30 days from the date of purchase to return it. All return communication is handled by our team at Recovery Room Direct. You do not need to contact the manufacturer or the distributor yourself.
Condition required. The unit must be new, uninstalled and in resalable condition with its original packaging and all included parts. A heater that has been wired in, fired, or loaded with stones counts as installed and cannot be returned.
How to start a return. Call (888) 500-5675 or email sales@recoveryroomdirect.com with your order number. A Return Authorization number is required before anything goes back, and product returned without one can be refused. We will give you the RA number and the return address.
What a return costs. You get full credit for the product, less a repackaging fee that typically runs about 20 to 50 dollars depending on the item. There is no percentage restocking fee on a standard customer return, which is better than most of what we carry, where 15 to 20 percent is normal.
Who pays the return freight. You do on a change of mind. We do, and the distributor does, when the cause is shipping damage or an error on our side. Nothing is deducted for freight in those cases.
Damaged on arrival is a different process, and it is time sensitive. Note the damage on the delivery receipt before you sign, photograph the carton and the contents, and call us the same day. Concealed damage found after signing is much harder to claim, so open the box on delivery day even if you are not installing for weeks.
Sauna stones. Stone is sold by weight and is not returnable once a box is opened. Order the quantity your model takes and ask us if you are unsure, because the amount is set by the heater rather than by the room.
Control units and accessories. Same 30 day window and the same condition requirement. A control unit that has been wired in cannot be returned.

PRODUCT DESCRIPTION

Harvia Virta Combi Series
Harvia Virta Combi HL110SA 10.5kW Electric Sauna Heater
The Virta Combi is a Harvia Virta with a steam generator built into the same cabinet. You get 154 lbs of stone for dry heat and loyly, plus a 2.1 kW steamer for the humid end of the range, on one control unit and one footprint.
At 10.5kW Harvia rates it for rooms up to 635 cubic feet, or 28 to 102 square feet of floor at a minimum ceiling height of 75 inches. The Combi runs from a Harvia CX30C control unit, bought separately and mounted outside the hot room. It has to be the C version, because the steamer needs a humidity sensor as well as a temperature sensor. A plain CX30 will not run this heater.
Affirm financing available at checkout. Speak with a recovery specialist on (888) 500-5675.
Harvia Virta Combi HL110SA Features
What you are buying at 10.5kW
154 lbs of stone
Stone capacity is what separates two heaters of the same output. More stone holds more heat, which means softer steam, a room that recovers faster between ladles, and less swing on the thermostat. Harvia rates this cabinet at 154 lbs of angular split-face stone between 2 and 4 inches.
2.1 kW steamer and a 1.3 gal reservoir
The Combi is two appliances in one cabinet. The stone heater gives you the dry heat and the loyly you get from throwing water on stone. Underneath it sits a 2.1 kW steamer with its own 1.3 gallon (5 litre) reservoir, which runs for roughly two hours on a fill and lets you hold a humid room at a lower air temperature. Fill the reservoir while the heater is cold, before every use, and drain it after. That is the part people forget, and a reservoir left standing is what shortens a steamer's life.
Steel body, ETL Listed
Steel construction rated IPX4 against splashing, floor mounted, with a maximum thermostat setting of 194°F. Harvia publishes an ETL listing for this heater covering the United States and Canada. ETL is the mark of Intertek, an OSHA-accredited Nationally Recognized Testing Laboratory. Installation follows the National Electrical Code and your local code.
Sizing the HL110SA
Is 10.5kW the right output for your room?
Measure length × width × height in feet. Harvia also publishes a floor area for this model, 28 to 102 square feet, at a minimum room height of 75 inches (1900 mm). The floor figure is the more useful check, because Harvia prints the same 177 cubic foot minimum against every heater in this range, which makes it a formatting artifact rather than a real lower limit.
Cold surfaces change the answer, and a glass door counts. Harvia's manuals treat brick, glass, tile and concrete as non-insulated surface and say to add 1.2 cubic meters of volume for every square meter of it, which works out near 3.9 cubic feet for every square foot. Harvia's own worked examples: a 10 cubic meter room with a glass door behaves like a 12 cubic meter room, and the same room with a 2 by 2 meter brick wall behaves like 15. If you are close to the limit, size up rather than down.
Log walls without insulation heat slowly. Harvia advises multiplying the room volume by 1.5 before choosing output in that case.
Electrical requirements
29.2 amps at 208 volts three phase
Worth settling before you price the electrical work. Harvia's US manual gives the HL110SA a rated amperage of 29.2 A at 208 volts three phase, with a minimum 10 AWG 90°C copper supply wire. Unlike the 240 volt Combi models, Harvia's table gives this three-phase version as a single connection at 29.2 A with no group split.
Harvia publishes rated amperage rather than a breaker size. Fixed electric heating counts as a continuous load, so your electrician sizes the conductor and the overcurrent device with headroom above that figure, to the National Electrical Code and to whatever edition your local authority has adopted.
The heater is hardwired. The US manual calls for copper wire rated to 194°F (90°C) within the sauna walls, run in seal tight conduit between the heater and the wall, and it is explicit that pigtails and plugs are not allowed in the sauna room.
Installation must be carried out by a licensed electrician. Harvia's warranty terms require that proof of professional installation is presented, so keep the invoice.

What's in the box
Included with your Virta Combi HL110SA
- Virta Combi HL110SA sauna heater
- Temperature sensor
- Installation and operation manual
- Heater only. A Harvia CX30C control unit is required and sold separately.
- Harvia manufacturer warranty, 2 years residential and 3 years when registered within 30 days, subject to professional installation
Sauna stones are required and are not included. Harvia rates the HL110SA to hold up to 154 lbs of stone. Order about 4 boxes at 44 lbs a box, which over-supplies a little on purpose: stone is natural and varies in shape, so you want enough to choose from and a few spares as they break down. Harvia specifies angular split-face stone 2 to 4 inches across for this range. Harvia's manual for this heater and the distributor's stone chart currently disagree on which Harvia stone code suits it, so we confirm the exact code with your order rather than have you guess. It matters, because unsuitable stone packs too tightly, restricts airflow through the heater and can void the warranty. Call (888) 500-5675 and we will add stones to your order.

Compare the Virta range
The HL110SA against the rest of the Virta range
Three families share the Virta name. The standard Virta is a dry stone heater. The Virta Combi adds a 2.1 kW steamer and a water reservoir in the same cabinet. The Virta Pro is the commercial tier and the only one that needs separate supply circuits; the single-phase Combi runs on one circuit split into two groups, because the steamer is fed alongside the heater elements. Room volumes are Harvia's published maximums.

Harvia Virta Combi HL110SA FAQ
Questions buyers ask about the HL110SA
What size sauna room does the Harvia Virta Combi HL110SA heat?
Harvia rates the HL110SA for rooms up to 635 cubic feet, or 28 to 102 square feet of floor at a minimum ceiling height of 75 inches. Multiply your room length, width and height in feet to get the volume. Non-insulated surface counts, and so does a glass door: Harvia adds 1.2 cubic meters of volume for every square meter of brick, glass, tile or concrete, which is near 3.9 cubic feet for every square foot. Add that before you compare against the range.
Does the HL110SA need a separate control unit?
Yes, and it has to be a Combi control. The HL110SA runs from a Harvia CX30C unit, which carries a humidity sensor as well as a temperature sensor because it is managing the steamer as well as the heater. A plain CX30 will not run this heater. The control unit is bought separately and mounts outside the hot room.
How many circuits does the HL110SA require?
One. Harvia's US manual gives the HL110SA a rated amperage of 29.2 A at 208 volts three phase, with a minimum 10 AWG 90 degree Celsius copper supply wire. Harvia specifies this as a two-group connection, so the feed is split between the heater elements and the steamer. Harvia publishes rated amperage rather than breaker size, so your electrician sizes the overcurrent device above that figure, because fixed electric heating counts as a continuous load.
How long does the steamer run on one fill?
About two hours. The HL110SA carries a 1.3 gallon (5 litre) reservoir feeding a 2.1 kW steamer. Fill it with clean household water while the heater is cold, before every use, and drain it afterwards. Leaving water standing in the reservoir is the single most common reason a steamer fails early. Some Combi models can be plumbed for automatic filling instead, which is worth asking about if the sauna is in commercial use.
What is the difference between the Virta Combi and the standard Virta?
Output and stone capacity are the same. The Combi adds a 2.1 kW steam generator and a water reservoir inside the same cabinet, so you can run the room humid at a lower air temperature instead of only dry and hot. It is a deeper cabinet, it draws more current, and it needs the Combi version of the control unit. If you only want traditional dry heat and loyly, the standard Virta at the same output costs less to buy and to wire.
Are sauna stones included with the Virta Combi HL110SA?
No. Stones are required for operation and are sold separately. Harvia rates the HL110SA to hold up to 154 lbs of stone, and the practical order is about 4 boxes at 44 lbs a box, which over-supplies a little on purpose: stone is natural and varies in shape, so you want enough to choose from and a few spares as they break down. Harvia's manual for this heater and the distributor's stone chart currently disagree on which Harvia stone code suits it, so we confirm the exact code with your order rather than have you guess. Harvia specifies angular split-face stone 2 to 4 inches across for this range. Stone that is too small, too flat or the wrong shape packs tightly and restricts the airflow the heater depends on, and Harvia's terms exclude damage caused by stone it does not recommend.
Can I install the Harvia Virta Combi HL110SA myself?
No. The HL110SA is hardwired and must be installed by a licensed electrician to the National Electrical Code and local requirements. Harvia's published warranty terms require that proof of professional installation is presented, so keep the invoice. The US manual specifies copper wire rated to 194 degrees Fahrenheit within the sauna walls, run in seal tight conduit, and states that pigtails and plugs are not allowed in the sauna room.
What warranty comes with this heater?
Harvia covers this heater for 2 years in residential family use, including the heating elements, under the Limited Warranty for Harvia Products dated 18 November 2025. Register the heater with Harvia within 30 days of purchase and Harvia adds a third year, for 3 years in total. Registration is free and takes a couple of minutes. We send you the link and your serial number with your order, so you do not have to go looking for it. In commercial or other non-consumer use the period is 2 years on the heater, controls and electronics, and 6 months on the heating elements. Cover runs from your date of purchase, so keep your receipt. Harvia also requires that the unit is installed and wired by a licensed electrician and that you can show proof of professional installation, so keep your installer's paperwork with it. Transport or storage damage is separate and must be reported no later than seven days after delivery. Harvia US Inc. is the warrantor and handles claims directly, and we open the claim on your behalf. Full terms are on our Harvia warranty policy page.
Is the Virta Combi HL110SA listed for use in the United States?
Harvia publishes an ETL listing for this heater covering the United States and Canada. ETL is the mark of Intertek, an OSHA-accredited Nationally Recognized Testing Laboratory. Installation follows the National Electrical Code and your local code.
Does the HL110SA need a GFCI breaker?
Harvia's manual is explicit that the power feed should not be connected through a GFI or residual current device. Local code may require GFCI protection anyway, particularly outdoors or in a wet location, and where the two conflict your inspector decides. Settle it with your electrician before the rough-in rather than at final inspection.
