The electrical supply required will depend on the kW rating of your chosen sauna heater. We strongly recommend consulting with a qualified electrician prior to any installation.
Typically, a dedicated supply is required—similar to those used for electric showers or cookers. Most domestic sauna heaters in the UK are connected to a single-phase 230V supply, and the Amps can be calculated using:
Watts ÷ Volts = Amps
For example: a 6kW (6000W) heater ÷ 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).
