| 6.9 – 11 kW | ✅ Yes | Three-phase recommended |
| 11 – 17 kW | ✅ Yes | Three-phase required |

- Harvia Topclass Series
- Harvia Vega Series
- Most other Harvia electric heaters without integrated controls
⚠️ Note: This control unit is NOT compatible with heaters that have built-in control panels.
💷 Energy Considerations
Unlike a sauna heater, the control panel itself consumes minimal power. However, here’s what to consider for your overall sauna running costs:
Control Panel Power Consumption:
- Standby mode: Less than 5W
- Active operation: Minimal (control circuits only)
Sauna Heater Running Cost Example:
Based on current UK electricity rates (Ofgem Price Cap Q4 2025: £0.2635/kWh):
| Heater Size | 1-Hour Session | 1.5-Hour Session | Weekly (4 sessions) |
|---|---|---|---|
| 6 kW | £1.58 | £2.37 | £9.48 |
| 9 kW | £2.37 | £3.56 | £14.22 |
| 12 kW | £3.16 | £4.74 | £18.96 |
| 17 kW | £4.48 | £6.72 | £26.88 |
Calculation Formula:
Session Cost = Heater kW × Hours × £0.2635
Example (9 kW heater, 1.5-hour session):
9 kW × 1.5 hours × £0.2635 = £3.56 per session
⚠️ Actual costs depend on your heater size, session duration, insulation quality, and current energy rates.
