📐 Room Sizing Guide

Basic Formula:

1 kW = approximately 1 - 1.5 m³ sauna room volume

Adjustment Factors:

Condition	Adjustment
Glass door/windows	+1.5 m³ per m² of glass
Uninsulated/log walls	+25-50% to volume
Outdoor/barrel sauna	+25-30% to volume
High ceiling (above 2.3m)	Add extra volume

Worked Example:

📍 Example Room: 2m × 1.6m × 2.1m
- Base volume: 6.72 m³
- Glass door (0.7m × 1.9m = 1.33 m²): +2.0 m³
- Total calculated: 8.72 m³
- This 6 kW heater: ✅ Suitable for 5-8 m³ (consider 9kW if glass door is large)

Recommended Room Dimensions for 6kW:

• Minimum room volume: 5 m³
• Maximum room volume: 8 m³ (well-insulated)
• Minimum ceiling height: 1900 mm

💷 Running Costs

Energy Rate Used: £0.28/kWh (Ofgem price cap Q1 2026 average – 27.69p/kWh rounded)

Cost Calculation:

Usage Level	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	2	150	£252
🏠 Regular Use	4	300	£504
🧖 Heavy Use	6	450	£756

Calculation Formula:

Annual Cost = kW × Hours/Year × £0.28

Example (6 kW heater, Regular Use):
6 kW × 300 hours × £0.28 = £504 per year

Per session cost: Approximately £2.52 per 1.5 hour session
(6 kW × 1.5 hours × £0.28 = £2.52)

⚠️ Actual costs depend on usage patterns, session length, insulation quality, and current energy rates. The heater cycles on/off during operation, so actual consumption is typically 60-70% of maximum rated power.

❓ Frequently Asked Questions

Q: What size room will this heater work for? A: This 6 kW heater is suitable for sauna rooms between 5 and 8 m³. For rooms with glass doors, large windows, or uninsulated walls, add 25-50% to your volume calculation. If your adjusted volume exceeds 8 m³, consider the 9 kW Spirit model instead.

Q: How long does it take to heat up? A: Typically 30-45 minutes to reach optimal bathing temperature (70-90°C), depending on room size, insulation quality, and starting temperature. The WiFi control allows you to preheat remotely so your sauna is ready when you arrive.

Q: What electrical supply do I need? A: The heater supports multiple supply options: 400V three-phase, 230V single-phase, or 230V three-phase. Most UK residential installations use 230V single-phase requiring a dedicated 25A circuit. Professional installation by a qualified electrician is required.

Q: Are sauna stones included? A: No, sauna stones are sold separately. This heater requires approximately 60 kg of rounded olivine diabase stones (5-10 cm diameter). We recommend Harvia R-991 stones available from Parts4Tubs.

Q: What is the warranty? A: The heater comes with a 3-year manufacturer warranty. Contact Parts4Tubs for full warranty terms and conditions.

Q: Can I install this outdoors? A: Yes, this heater can be installed in outdoor garden saunas, barrel saunas, and cabin saunas provided the sauna room is properly insulated and protected from direct weather exposure. Add 25-30% to your room volume calculation for outdoor installations.

Q: Is an RCD required? A: No – sauna heaters should NOT be connected through an RCD (residual current device) as the heating elements can cause nuisance tripping. A standard MCB (miniature circuit breaker) of the appropriate rating is required.
