How does delivery work?
How does delivery work?
Free to the contiguous 48. What changes across the range is not the cost to you but how it arrives.
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 and nobody needs to be home.
Wood burning stoves ship by freight. A stove moves palletized on an LTL carrier. The carrier calls to arrange an appointment window, someone must be there to sign, and it is a curbside drop rather than a carrier leaving it at the door.
Stones ship separately. A heater takes anywhere from one box to thirteen at roughly 44 pounds a box, so stone shipping is charged per box at checkout, including when the stones are ordered with a heater.
When it ships, and how you will know. Most orders ship promptly, though some part numbers are supplied from Finland and take longer, so we confirm the position for your specific model when you order. You get a tracking notification by email once it ships.
Where we ship. The contiguous 48 states. Alaska, Hawaii, Puerto Rico and Canada are quoted case by case, so contact us before ordering.
If it arrives damaged. 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.
What does the warranty cover?
What does the warranty cover?
Residential coverage. Two years on electric heaters, controls and steam generators including the heating elements, and two years on wood burning stoves, running from your date of purchase.
A free third year. Register within 30 days and Harvia adds a third year on electric heaters in residential use. We send you the link and your serial number with your order.
Commercial coverage. Two years on electric heaters, controls and electronics, but six months on heating elements and six months on wood burning stoves.
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. A heater wired by the owner is outside the warranty, so keep your installer's invoice with your receipt.
Not covered. 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.
Transport damage has a seven day limit. Harvia requires damage found on receipt to be reported no later than seven days after delivery. Call us the same day, because a claim is far easier to win with the damage noted on the delivery receipt.
Changing how you use it ends the cover. 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.
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.
Who handles it. Harvia US Inc. is the warrantor for North America and we open the claim with them on your behalf. Call (888) 500-5675.
What if I need to return it?
What if I need to return it?
30 days from purchase. 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.
What a return costs. There is no percentage restocking fee on a standard customer return. You get full credit for the product, less a repackaging fee that typically runs about 20 to 50 dollars depending on the item.
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, and nothing is deducted for freight in those cases.
Damaged on arrival. 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.
Controls and accessories. Same 30 day window and the same condition requirement. A control unit that has been wired in cannot be returned.
To start a return. Call (888) 500-5675. A Return Authorization number is required before anything goes back, and product returned without one can be refused.
PRODUCT DESCRIPTION
Harvia The Wall Series
Harvia The Wall SW80 8kW Electric Sauna Heater
The Wall is exactly what the name says. At 10.2 inches deep it hangs flat against the sauna wall and gives you the bench space back, with the timer and thermostat built into the base so there is no controller to buy.
At 8kW Harvia rates it for rooms up to 431 cubic feet, or 28 to 69 square feet of floor at a minimum ceiling height of 75 inches. Time and temperature are set with dials on the heater itself, so there is no separate wall control unit to buy, wire or find space for.

Harvia The Wall SW80 Features
What you are buying at 8kW
10.2 inches deep, wall hung
The whole cabinet is 17 by 10.2 by 27.6 inches and it mounts on the wall, so it takes no floor and no bench. In a small room that is often the difference between a two-person bench and a one-person bench. The trade is stone: 44 lbs against 110 in a floor heater at the same output, so it recovers a little slower after each ladle and the steam is thinner.
Timer and thermostat on board
Dials on the heater itself set the temperature and the run time, so there is no wall controller to buy, no second cable run and no extra hole in the sauna wall. That keeps the install simple and the total cost down. The trade is that you set it inside the room rather than preheating from your phone.
Steel body, ETL Listed
Steel construction, wall 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 SW80
Is 8kW the right output for your room?
Measure length × width × height in feet. Harvia also publishes a floor area for this model, 28 to 69 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.
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
33.4 amps at 240 volts single phase
Worth settling before you price the electrical work. Harvia's US manual gives the SW80 a rated amperage of 33.4 A at 240 volts single phase, with a minimum 8 AWG 90°C copper supply wire. A two-circuit option is offered at 22.3 A and 10 AWG per circuit, but it is an alternative rather than a requirement.
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 The Wall SW80
- Harvia The Wall SW80 sauna heater
- Wall mounting hardware
- Installation and operation manual
- Timer and thermostat built into the heater
- 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 SW80 to hold up to 44 lbs of stone. Order 1 box of Harvia AC3000 at 44 lbs a box, which fills the rated capacity almost exactly, so order a spare box if you want extra to choose from as stone varies in shape and breaks down over time. Harvia specifies angular split-face stone 2 to 4 inches across for this heater. 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. Call (888) 500-5675 and we will add stones to your order. Want it in one order? The Harvia The Wall SW80 package pairs it with a box of AC3000 stone.

Harvia The Wall SW80 FAQ
Questions buyers ask about the SW80
What size sauna room does the Harvia The Wall SW80 heat?
Harvia rates the SW80 for rooms up to 431 cubic feet, or 28 to 69 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.
What is the difference between the SW and SWS versions?
Finish only. SW is Harvia's BlackSteel finish and SWS is stainless steel. Same output, same dimensions, same stone capacity, same wiring and the same manual covers both. Choose on how it will look against your sauna wall.
Does a wall-mounted heater perform as well as a floor heater?
For heat output, yes: 8 kW is 8 kW and the room reaches temperature the same way. The difference is stone. The Wall holds 44 lbs, where Harvia's Virta floor heater of the same output holds 110 lbs, and stone is the thermal buffer. Less of it means the room swings a little more on the thermostat, recovers slightly slower after each ladle, and gives a thinner burst of steam. In a small room used by one or two people that is a fair trade for the floor space and the bench you get back.
Does the SW80 need a separate control unit?
No. The timer and thermostat are built into the heater itself, so there is no wall controller to buy, no second cable run and no extra penetration in the sauna wall. You set the temperature and the run time on the heater itself. The trade is that you cannot start it remotely, so if preheating from your phone matters, look at a model that takes a Harvia Xenio control instead.
How many circuits does the SW80 require?
One. Harvia's US manual gives the SW80 a rated amperage of 33.4 A at 240 volts single phase, with a minimum 8 AWG 90 degree Celsius copper supply wire. A two-circuit option is offered at 22.3 A and 10 AWG per circuit, but it is an alternative rather than a requirement. Harvia publishes rated amperage rather than breaker size, so your electrician sizes the overcurrent device above that figure.
Are sauna stones included with The Wall SW80?
No. Stones are required for operation and are sold separately. Harvia rates the SW80 to hold up to 44 lbs of stone, and the practical order is 1 box of Harvia AC3000 at 44 lbs a box, which fills the rated capacity almost exactly, so order a spare box if you want extra to choose from as stone varies in shape and breaks down over time. Harvia specifies angular split-face stone 2 to 4 inches across for this heater. 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 The Wall SW80 myself?
No. The SW80 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 Wall SW80 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 SW80 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.
