Getting your sauna heater installed

Home sauna heaters

Most home sauna heaters aren’t plug-and-play. They must be hardwired by a qualified electrician on a dedicated circuit like a shower or oven.

What to tell your electrician:

“I’m installing a [X kW] sauna heater. It needs connecting to a dedicated circuit, local isolator, RCD/MCB protection, and testing/certification.”

Commercial sauna heaters

Larger commercial heaters often require a 3-phase supply. Contact us and we’ll provide the exact technical specifications for your electrician.

Calculate the heater kW needed for your sauna

Enter the details of your sauna size below to output the recommended sauna heater kW. Cold areas such as full glass front or door should be added for a better match.

Rule of thumb: Allow around 1kW per 1m³ of effective sauna volume. Extra glass, tile, stone, and log construction can push the requirement higher.

Description

The Harvia Qube sauna heater is a sleek, high-performance choice for medium to large saunas, combining strong heat output with a clean, minimalist look. Its black and brushed stainless-steel finish gives it a refined presence, ensuring it sits comfortably in any modern sauna or design-conscious wellness space. If you want a heater that feels substantial without looking clunky, the Harvia Qube is a fine choice.

What makes the Harvia Qube especially appealing is the way it balances power, safety and practicality. The multi-layer structure helps keep the outer body safer to touch while supporting good air circulation and efficient heat retention around the stones. Inside, the separated stone chamber and heating elements are designed to make servicing easier and help support long-term reliability.

For saunas where dependable performance matters, the Harvia Qube is a strong fit. It heats quickly, delivers a satisfying löyly, and offers the kind of durable, easy-clean construction that makes ownership feel straightforward rather than fussy.

Controls

  • None: Choose this option if you are buying the heater only.
  • Harvia Xenio CX170: A standard digital control available for the 9kW and 10.5kW versions. A good choice if you want straightforward, non-app control.
  • Harvia Xenio CX170XW WiFi: A Wi-Fi and app-enabled control available for 9kW and 10.5kW versions, and for 12kW and 15kW versions with the required LTY17 power extension box included.

Important: 12kW and 15kW controlled versions include the required LTY17 power extension box. 9kW and 10.5kW versions do not need it.
