Sauna Heaters

Topture's sauna heater collection holds 66 heaters from Harvia, HUUM, Saunum, Amerec and SaunaLife: electric heaters, wood-burning stoves and one propane heater. Their makers rate them by sauna room volume, for example 70–100 cubic feet for the Amerec Junior 2.2 kW and 706–1,766 for the Harvia 50 wood stove.

Sauna heaters by fuel, room size and brand

A sauna heater short list comes from four choices:

Fuel. With the fuel settled, start with the electric sauna heaters, the wood-burning sauna heaters or, for the propane heater here, the gas sauna heaters.
Room size. For a small sauna room, start with the mini sauna heaters; the commercial sauna heaters have a page of their own.
Brand. To shop one maker, go to the Harvia sauna heaters, the HUUM sauna heaters or the Saunum sauna heaters.
Replacing a heater. If you are replacing the heater in a sauna you already have, start with the replacement sauna heaters.

How to choose a sauna heater weighs the makers against one another, and wood and electric sauna heaters compared sets the two fuels side by side.

Sauna heater types compared: electric, wood-burning and propane

Sauna heater types narrow the choice like this:

Electric. Choose an electric heater if you would rather set a temperature than tend a fire, and the supply its maker lists can run to the sauna.
Wood-burning. Rule out a wood-burning stove if the sauna cannot take a chimney and the non-combustible base or floor protection its manual asks for: HUUM's HIVE Wood manual asks for a non-combustible surface with the required carrying capacity, Harvia's M3 manual asks for Harvia protective bedding under the stove on a floor of inflammable material, with nonflammable floor protection in front of the door, and Topture's M3 listing puts the chimney under what you need separately.
Loaded from outside. Choose a stove loaded from another room or from outside if you want to feed the fire without going into the sauna: 10 stove listings here include such a model, among them Harvia's M3 SL, which Harvia designed for heating the sauna from another room or outside the building.
Propane. Choose the SaunaLife Titan SL1 only where SaunaLife's manual allows it: in a sauna room or cabin built to its clearance and ventilation rules, or in SaunaLife's own SaunaTrekker tents, with the exhaust vented directly outdoors and the propane cylinder kept outside.

How much does a sauna heater cost?

Sauna heater prices in this collection run from $886 for the Harvia Vega Compact 3500 to $7,587 for the Harvia 50 wood stove, each listing's lowest current price across its models and options.

Harvia's Vega Compact heaters and its M3 stove sit toward the lower end here. Saunum's Air L heaters and the Harvia 50 stove sit toward the upper end.

A separate-control heater's listed price does not include its control: Harvia's KIP manual, for one, says the control unit for the separate-control KIP must be purchased separately. Harvia's KIP and HUUM's DROP also ship without sauna stones, and their product pages offer stones as an add-on.

Freight within the contiguous United States is included in the price of the Harvia, HUUM, Saunum and Amerec heaters here. Compare sauna heaters on the installed total: the heater, the control a separate-control model needs, its stones, and the electrician's or the chimney installer's work.

Sauna heater size and room volume

A sauna heater is sized to the room's volume: multiply the inside length, width and height in feet, then choose a model whose maker's printed minimum–maximum range covers the result.

Harvia's and Saunum's manuals, and several of HUUM's, add volume to the room for walls without insulation. Harvia adds about 3.9 cubic feet for each square foot of uninsulated wall such as glass, brick, concrete or tile, and multiplies a solid-log sauna's volume by 1.5. HUUM's US manuals for the CLIFF and STEEL heaters add 3.3 cubic feet per square foot of uninsulated brick, tile or glass. Its HIVE and HIVE Flow manuals add the same. Saunum's Air manuals add 3.0 cubic feet per square foot of glass, tile, brick, concrete or stone and multiply the volume by 1.5 for log, plank or stave walls without internal insulation.

For a room of about 250 cubic feet with insulated walls and no glass, start with the 6 kW sauna heaters: Harvia rates the KIP 6 kW for 170–300 cubic feet and HUUM the DROP 6 kW for 177–318 on a 240 V supply. Rule out any heater whose printed range stops short of your room's adjusted volume; where the result falls between two sizes, Saunum's manuals say to choose the larger heater.

Built-in or separate control, Wi-Fi and stones for sauna heaters

Sauna heaters here differ in how they are controlled and in what comes in the box:

Built-in control. Six electric heaters here carry their thermostat and timer on the heater itself, Harvia's KIP with built-in controls among them, and Harvia documents no Wi-Fi control for those six. Choose one of them if you want no app and no separate panel.
Separate control. 30 electric heaters here have no control of their own and need a separate control unit, such as HUUM's UKU, Saunum's Air IQ or Harvia's Xenio; controls bought on their own are under sauna heater controls. Both Amerec Junior heaters are among the 30: Sauna360 wires the Junior through a separate contactor box to its SaunaLogic2 or H3 control, and Topture sells neither control.
Wi-Fi. For control from a phone app, choose a separate-control heater and its maker's Wi-Fi control: HUUM's UKU Wi-Fi runs its electric heaters from the HUUM app, while the UKU Local is run from its wall panel only, with no app; Saunum's Air IQ adds remote control through the Saunum app; and Harvia's Wi-Fi Xenio and Fenix controls connect to the MyHarvia app. Browse the sauna heaters with Wi-Fi control next.
Stones. If you would rather not buy the control and stones separately, start with the sauna heaters with rocks: Topture's HUUM DROP 6kW Electric Heater Package, for one, combines the DROP 6 heater, a HUUM UKU control and HUUM stones as one item.

Sauna heater electrical supply and running cost

A sauna heater's electrical supply is set by its maker, and the supply options here are:

240 V. Choose from the 240 V heaters if a 240 V circuit can run to the sauna: Harvia's KIP manual lists the KIP 6 kW at 25 amps on 240 V single-phase, and HUUM's US manual lists the DROP 6 kW at the same 25 amps on 240 V.
Three-phase. If your building has a 208 V three-phase supply, choose from the five Harvia heaters here with a three-phase version: the stainless KIP with separate control, the Club, the 10.5 kW Virta and Virta Combi, and the Virta Pro 20 kW, which runs on three-phase only.
208 V. If the supply at the sauna is 208 V, the HUUM CLIFF and STEEL are an option too: HUUM's US manuals rate both for 208 V as well as 240 V.
120 V. If the sauna has no 240 V supply, two heaters here also run on 120 V: Harvia lists the Vega Compact 1900 at 15.9 amps on 120 V and Sauna360 the Amerec Junior 2.2 kW at 18.3 amps on 120 V, and both makers require the heater to be permanently wired in by a licensed electrician.
No electricity. If the sauna has no electrical supply at all, look at the wood-burning stoves and the propane heater: HUUM describes its HIVE Wood as a choice for saunas without access to electrical connections, and SaunaLife says the Titan SL1 needs no electricity.

A sauna heater's electricity use depends on its output and how long it runs. Harvia rates the Vega Compact 1900 at 1.9 kW and HUUM the HIVE 18 at 18 kW, and your electricity rate and session length set the running cost. HUUM's UKU manual asks for the control to go on a dedicated circuit and says its electrical work may only be done by a licensed electrician; before you get a quote, read what a sauna heater circuit involves. Your licensed electrician sizes the breaker and wire from the manual that ships with the heater and your local code.
