Frequently Asked Questions
What size sauna room is this heater designed for?
The Harvia KIP80W is rated for sauna rooms between 250 and 425 cubic feet. To calculate your room volume, multiply the interior length × width × height in feet. If your room falls outside this range, a different heater model may be more appropriate.
Is the Harvia Xenio control included?
No. The Harvia Xenio WiFi control is required for operation but is sold separately. The KIP80W is not compatible with other control systems—you must use the Harvia Xenio to operate this heater.
Are sauna rocks included?
No. Sauna rocks (45 lbs required) are sold separately. Do not operate the heater without the stones properly loaded, as this can damage the heating elements.
What voltage does this heater require?
The KIP80W is available in two electrical configurations: 240V 1-Phase and 208V 3-Phase. Select the correct variant for your electrical service at checkout. Confirm your available voltage and phase with a licensed electrician before ordering.
What wire size is required for installation?
Installation requires 8 Gauge Copper wire. Use of undersized or aluminum wiring is not recommended and may create a safety hazard. All wiring must be installed by a licensed electrician per local code requirements.
How does the WiFi control work?
The KIP80W connects to the Harvia Xenio WiFi control unit (sold separately). Once installed and paired, you can adjust temperature, set schedules, and turn the heater on or off remotely using the Harvia app on your smartphone. WiFi connectivity requires a standard home network.
What is the difference between the Stainless Steel and Black finishes?
Both finishes offer the same performance and specifications. The Stainless Steel finish has a brushed metallic appearance, while the Black finish provides a matte dark look. The choice is purely aesthetic—select the finish that best complements your sauna interior.
Can I install this heater myself?
The mechanical mounting of the heater can be completed by a capable DIYer following the installation manual. However, all electrical connections must be made by a licensed electrician. Improper electrical installation is a safety hazard and may void the product warranty.
