Leil® Black Cube Comfort 6-8 Person Outdoor Sauna

Electrical Installation – Important Information

If you hire our installation team to build your sauna, please note that internal electrical wiring is not included and must be completed by a certified electrician.

Our installation team will:

• Mount the sauna heater to the wall (where applicable)
  
• Attach the LED light strips to the benches

However, the following must be completed by a qualified electrician:

• Final wiring and connection of the heater
  
• Final wiring of the LED lighting
  
• Installation and wiring of external control panels, door sensor, thermostat, and any other electrical components (not applicable for manually controlled heaters such as the Harvia Vega BC60).

Electrical Supply Requirements

A sauna heater typically requires a dedicated electrical supply, similar to those used for electric showers or cookers.

Most domestic sauna heaters in the UK operate on a single-phase 230V supply. The current draw can be calculated using the following formula:

Watts ÷ Volts = Amps

Example:

6kW (6000W) ÷ 230V = approximately 26 Amps

Below is a general guide for domestic sauna heaters:

Heater Power - Current Draw - Suggested Cable Size (Single-Phase)

2.3 kW - 10 Amps - 1.5 mm²

3.0 kW - 13 Amps - 2.5 mm²

3.6 kW - 15 Amps - 2.5 mm²

4.5 kW - 19 Amps - 2.5–4.0 mm²

6.0 kW - 26 Amps - 4.0 mm²

8.0 kW - 35 Amps - 6.0 mm²

9.0 kW - 40 Amps - 6.0 mm² (or higher, depending on cable run)
Cable size depends on cable length, installation method, and other on-site factors. Always defer to your electrician’s judgment.

We strongly advise that installation is carried out by a fully qualified electrician, and that all work complies with current Government regulations and wiring standards (e.g., BS 7671 in the UK).
