The Harvia Spirit SP80E is an 8 kW wall-mounted electric sauna heater for rooms of 177–431 adjusted cubic feet running on 240VAC 1PH. It takes 110 lb of 5-10cm sauna stones (sold separately). It requires a separate Harvia control unit, sold separately.
The Harvia Spirit takes the wall-mounted format and wraps it in a rounded Graphite Black stone cage that holds 110 lb of rounded Olivine diabase — more than double the stone mass of a conventional wall heater like the KIP. More stone means a slower, softer, more forgiving steam and a heater that holds temperature between pours instead of spiking and crashing.
- Stylish and high-quality heater
- Heats up the sauna quickly and safely
- Integrated safety functions ensure safe use
- 110 lb rounded stone mass — roughly 2.5× a standard wall heater
- Graphite Black powder-coated cage

Hardwired on a dedicated circuit. Not a plug-in appliance. Who Installs It
A licensed electrician sizes the breaker and conductors from the nameplate and installation manual under the current NEC. Line Fuse
Harvia's published line-fuse value for this model does not agree with its own rated amperage, so we have not printed it. Size from the nameplate.
The Harvia Spirit SP80E is rated for 177–431 adjusted cubic feet.
Adjusted cubic feet = width × depth × height in feet, plus 45 cu ft for every square foot of glass, tile, concrete or stone, plus 15 cu ft for every square foot of exposed log wall. A 6 × 7 ft room with a 7 ft ceiling is 294 raw cu ft — add a full-glass door and it becomes 834. Always size to the adjusted number.
| Model | Output | Room Volume | Stones | Rated Amps |
|---|---|---|---|---|
| Spirit SP60E | 6 kW | 177–294 cu ft | 110 lbs | 25 |
| Spirit SP80E | 8 kW | 177–431 cu ft | 110 lbs | 33.3 |
| Spirit SP90E | 9 kW | 177–494 cu ft | 110 lbs | 37.5 |
- Mount to the clearances given in the installation manual. The temperature sensor goes on the wall above the heater, at the height the manual specifies.
- Load the stones loosely by hand, largest at the bottom, so air moves freely between them. Never run the heater with an empty or tightly packed stone space.
- Pour small ladlefuls of clean water onto the hot stones only — never onto the body, elements or controls. Mix any scented oil into the bucket first.
- Re-stack the stones once a year and replace any that have cracked or crumbled.
- Stones ship separately on their own freight because of the weight.
Does the Harvia Spirit SP80E include a control unit?
No, and it cannot run without one. It needs a separate Harvia control unit, sold separately: Harvia Xenio CX45. The control mounts outside the hot room, which is what lets you preheat the sauna before you walk in.
Can the Harvia Spirit SP80E be plugged into a normal outlet?
No. It is a hardwired appliance on its own dedicated circuit, rated at 33.3 A. A licensed electrician sizes the breaker and conductors from the nameplate and installation manual.
How long does the Harvia Spirit SP80E take to heat up?
Harvia does not publish a figure. A correctly sized, well-insulated room is usually ready in 30 to 60 minutes. Consistently longer than an hour normally means the heater is undersized for the room's adjusted cubic feet.
