These published room-volume ranges are starting points, not a final sizing recommendation. Electric models are rated in kW, while the wood-fired heaters require combustion and chimney planning. Room materials, heat loss, local codes, and each model’s installation manual determine the appropriate setup.

| Designer | Electric | 100–425 cu ft | 4.5 / 6 / 8 kW | Wall-mounted |
| Himalaya | Electric | 175–500 cu ft | 6.8 / 9 kW | Floor-standing |
| Laava | Electric | 390–950 cu ft | 10.5 / 12 / 14.4 kW | Floor-standing |

Confirm current specifications, availability, clearances, and exact variant with the manufacturer and our team. Electric kW figures are not comparable to wood-fired heat output. For more details, see Finnleo heater information and our wood-burning sauna heater guide.
Electric controls and wood-fired planning.
For electric models, choose the heater and control as a compatible system. Finnleo offers SaunaLogic controls and app-based operation on supported configurations, while certain Designer variants offer integrated in-room controls.
Wood-burning heaters work differently: there is no equivalent electronic temperature-control selection. Instead, plan safe flue routing, combustion air, clearances, and the manufacturer-approved installation with qualified professionals.
Plan the heater around the entire sauna room.
Share your room dimensions, building conditions, and preferred heat source. We can help you compare suitable models and identify which installation details need professional review.
- Room measurements: finished length, width, ceiling height, and room volume.
- Construction: glass, masonry, insulation, ventilation, and indoor or outdoor location.
- For electric heaters: voltage, phase, circuit capacity, control compatibility, and required clearances.
- For wood-burning heaters: chimney/flue pathway, combustion air, floor and wall protection, clearances, permits, and manufacturer instructions.
- Use case: residential or commercial, bench configuration, and anticipated operating schedule.

Should I choose an electric or wood-burning sauna heater?
Electric heaters offer convenient control and require appropriately designed electrical service. Wood-burning stoves deliver traditional fire-heated sauna warmth but need combustion-air and chimney planning, proper clearances, and qualified installation. Your room, location, preferences, and local requirements should guide the choice.
How do I choose the right heater size?
Start with the finished room volume, then account for glass, masonry, insulation, and ventilation. Use the correct manufacturer guidance for your selected electric or wood-burning model. Final specifications must be reviewed before ordering.
Can I reuse the controls from my old electric heater?
Compatibility depends on the exact electric heater, control, and power unit. Share the existing model information so our team can review replacement options. Wood-burning stoves do not use these electric control systems.
What is included in a sauna heater quote?
Confirm the heater, stones, compatible controls where applicable, delivery, accessories, and installation scope. For a wood-burning unit, also discuss chimney components and required protective measures. Inclusions depend on your project.
Do you assist with heater repairs and replacements?
Our team can discuss sauna heater service and replacement requirements. Electric troubleshooting and wood-fired stove or chimney inspections have different safety considerations, so use qualified professionals. Explore sauna repair services.
