Frequently asked questions
What is the difference between the Harvia KIP and the Harvia Spirit?
Both are traditional electric heaters that heat rocks for löyly. The KIP comes with built-in dial controls or with the Harvia Xenio WiFi controller, in 4.5, 6, or 8 kW. The Spirit comes with the Xenio WiFi controller, in 6, 8, or 9 kW, and has a curved shape designed to maximize airflow through the stones.
Can I start my sauna from my phone?
Yes, with a WiFi package. The KIP WiFi and Spirit WiFi packages include the Harvia Xenio WiFi controller, and the MyHarvia app lets you adjust the temperature, check heater status, and schedule sessions. The KIP dial uses built-in controls on the heater.
Which heater comes with my Blazin sauna?
Heater choices are listed on each sauna's product page. For example, the 2 Person Pod offers the Harvia KIP 6kW (dial or WiFi), the Harvia Spirit 6kW WiFi, or the Huum Drop 6kW WiFi. Our barrel vs pod vs cube guide lists the heater options for every model.
What size heater do I need?
Ask us which heater fits your model. Each product page offers heaters sized for that model, so the sizes listed there are the ones we recommend. Our heater sizing guide explains how it works, and we're happy to match a heater to your model.
Do I need an electrician?
Yes. A licensed electrician handles the hardwired hookup for an electric heater. Plan that early so the sauna is not waiting on power. See our foundation and electrical guide.
Do the heater packages include stones?
Yes. The Harvia KIP dial, KIP WiFi, and Spirit WiFi packages on our site each include sauna stones.
