Harvia sauna heaters: how the current lines differ
Last reviewed August 15, 2026
Harvia sells several heaters with similar names but very different controls and installation requirements. The useful question is not whether one line is "best." It is which exact item number fits your room, electrical plan, desired controls, and preferred amount of exposed stone.
Use the table for a shortlist. Then have the room calculation and installation plan checked before ordering. Glass, masonry, and other uninsulated surfaces can change the effective sauna volume.
| Example model | Format | Controls | Listed room range | Planning distinction |
|---|---|---|---|---|
| KIP60B | 6 kW wall-mounted electric | Built-in manual switches | Confirm exact item manual | Compact wall format; no remote operation |
| KIP60W | 6 kW wall-mounted electric | Separate control unit | 170-300 ft3 | Control package must be planned separately |
| Cilindro PC90E | 9 kW floor-standing electric | Separate control unit | 141-494 ft3 | Pillar format with 200 lb listed stone capacity |
| M3 | 16.5 kW wood-burning | Fire and air controls | 212-459 ft3 | Needs a compliant flue, shielding, and clearances |
| Legend PO70E | 6.8 kW floor-standing electric | Separate digital control | 212-353 ft3 | Large 220.5 lb listed stone capacity |
KIP60B: simple controls in a compact wall heater
The North American KIP60B item JH60BU1UL is a 6 kW, 240 VAC single-phase heater with manual controls on the unit. Harvia lists a temperature dial, an on/off timer with a delayed-start setting, 23.6 x 16.1 x 11-inch dimensions, and a 44-pound stone capacity.
This is the clearest fit when you want a conventional wall heater without a separate digital controller. It is not a remote-control model. Confirm the exact room range and electrical requirements in the manual tied to the retailer's item number; Harvia has more than one North American KIP60B record.

The KIP60W looks similar to the KIP60B, but Harvia lists item JH60WU1MUL as a separate-control model for rooms from 170 to 300 cubic feet. That single letter changes the control plan. Before ordering, ask which compatible control and power components are included and which are separate.

The North American Cilindro PC90E item HPCS9U1HUL is a 9 kW, 240 VAC pillar heater controlled by a separate unit. Harvia lists a 141-494 cubic-foot room range and 200 pounds of stones. Its open pillar format creates a much larger stone surface than the KIP, but it also changes the purchase list, placement, guard, and control decisions.
Do not treat the full published range as a shortcut around heat-loss calculations. The final heater size still depends on the room construction and the exact manual.

The M3, item WKM3, is a 16.5 kW wood-burning heater listed for 212-459 cubic feet. Harvia lists 66.2 pounds of stones, a glass door, and specific clearances on every side. It does not replace the need for chimney design, hearth protection, permits, and local fire-code review.
Choose wood because it fits the site and the way you want to operate the sauna, not because it appears easier than electrical work. The flue and clearance plan can be the larger part of the installation decision.

"Legend" is a family name, not one heater. Harvia currently lists electric and wood-burning Legend models. The electric PO70E, for example, is a 6.8 kW pillar heater for 212-353 cubic feet with a separate digital control and 220.5 pounds of stones. A Legend 240 SL is a 21 kW wood-burning model for a much larger room. Those are different projects.
Review the official electric Legend PO70E specificationsWhat to verify before paying
- Exact item number: model-family names alone do not establish the controls, certification, or electrical configuration.
- Calculated room volume: include the adjustment required by the manufacturer for glass, masonry, or uninsulated surfaces.
- Control package: confirm whether controls, sensors, contactors, and door devices are built in, included, or sold separately.
- Electrical plan: have a qualified professional confirm voltage, phase, breaker, conductor, disconnect, and local code requirements.
- Clearances and guards: use the current manual for the exact item rather than a reseller summary.
- Stone quantity: verify whether stones are included and buy the size and quantity specified for that heater.

Which Harvia sauna heater should I choose?
Start with calculated room volume and fuel type. Then compare the exact item number, controls, stone capacity, clearances, and complete installation package. A model-family name by itself is not enough.
Does the Harvia KIP60B include controls?
Harvia lists item JH60BU1UL with built-in manual controls. The similarly named KIP60W uses a separate control unit, so confirm the suffix and item number.
Can I install a Harvia electric heater myself?
Harvia says the electrical connection and service must be completed by an authorized electrical professional or another qualified person permitted by local regulations. Use the current manual and local code.
