The Harvia KIP45W is a 4.5 kW wall-mounted electric sauna heater for rooms of 100–210 adjusted cubic feet running on 208VAC 3PH or 240VAC 1PH. It takes 44 lb of 5-10cm sauna stones (sold separately). It requires a separate Harvia control unit, sold separately.
The Harvia KIP is the heater most home saunas end up with, and for good reason: it is a compact, wall-hung stainless steel unit that clears the floor completely, holds 44 lb of stones, and is available in the exact power steps that residential rooms need. It is also the only Harvia residential line offered both with built-in controls and as a bare heater for use with a separate wall-mounted controller.
- Requires wall-mounted time/temperature control
- Industrial grade, serviceable heating elements
- Exceptionally large rock capacity
- Direct rock-to-heating element contact
- Wall-mounted — keeps the floor clear for cleaning and drainage

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.
The Harvia KIP45W is rated for 100–210 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.

|---|---|---|---|---|
| KIP45W | 4.5 kW | 100–210 cu ft | 44 lbs | 18.8 |
| KIP60W | 6 kW | 170–300 cu ft | 44 lbs | 25 |
| KIP80W | 8 kW | 250–425 cu ft | 44 lbs | 33.3 |
- 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 KIP45W include a control unit?
No, and it cannot run without one. It needs a separate Harvia control unit, sold separately: Harvia Xenio CX170 (15 ft sensor cable, 240V 1PH) or Harvia Xenio CX170 (15 ft sensor cable, 208V 3PH). The control mounts outside the hot room, which is what lets you preheat the sauna before you walk in.
Can the Harvia KIP45W be plugged into a normal outlet?
No. It is a hardwired appliance on its own dedicated circuit, rated at 18.8 A. A licensed electrician sizes the breaker and conductors from the nameplate and installation manual.
How long does the Harvia KIP45W 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.
