Overview
Harvia KIP45B PKG 4.5 kW Sauna Heater Package – Built-In Controls, Stainless Steel
The Harvia KIP 4.5 kW is the compact choice in the KIP family, designed for smaller traditional sauna rooms. Harvia rates this output for sauna rooms from approximately 100 to 210 cubic feet, making it a practical fit for compact home saunas where wall space and heater clearance matter.
Is 4.5 kW the right size for your sauna?
Start with the interior room volume: width × depth × height. Then account for glass, tile, stone, masonry, or other uninsulated surfaces, because they can increase the effective heated volume. A room near the top of the 4.5 kW range may need the next heater size once those surfaces are considered.
Recommended room volume: 100–210 cu. ft.
Why choose the Harvia KIP 4.5 kW?
- Compact wall-mounted design: preserves floor space in smaller sauna rooms.
- Built-in controls: temperature and timer controls are located on the heater, so a separate wall controller is not required for normal operation.
- Traditional stone heat: the stone basket supports the classic sauna experience, including water on approved sauna stones when used according to the manufacturer instructions.
- Delay timer: the KIP built-in control system supports delayed start as described in the Harvia manual.
Installation planning
This is a hardwired electric sauna heater. Have a qualified electrician confirm voltage, circuit size, wiring, clearances, ventilation, and local code requirements before installation. Heater sizing should also be confirmed against the current Harvia manual for your exact room.
