📏 Room Sizing Guide

Basic Formula: 1 kW = approximately 1–1.5 m³ sauna room volume

Adjustment Factors

Condition	Adjustment
Glass door/windows	Add 1.2 m³ per m² of glass surface
Uninsulated surfaces (brick, concrete, tile)	Add 1.2 m³ per m²
Log/timber walls	Multiply total volume by 1.5
Outdoor/barrel sauna	Add 25–30% to calculated volume

Worked Example

📍 Example Room: 2.5m × 2.0m × 2.2m

• Base volume: 11.0 m³
• Glass door (0.8m × 2.0m = 1.6 m²): +1.92 m³
• Total calculated: 12.92 m³
• This 9.0 kW heater: ✅ Suitable for 8–14 m³ rooms

📍 Log Cabin Sauna: 2.0m × 1.8m × 2.1m

• Base volume: 7.56 m³
• Log wall multiplier: × 1.5 = 11.34 m³
• This 9.0 kW heater: ✅ Suitable

💰 Running Costs

Energy Rate Used: £0.277/kWh (Ofgem Price Cap Q1 2026)

Annual Cost Estimates

Usage Level	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	2	150	£374.85
🏠 Regular Use	4	300	£749.70
🧖 Heavy Use	6	450	£1,124.55

Calculation Formula

Annual Cost = Power (kW) × Hours/Year × £0.277

Example (9.0 kW heater, Regular Use):
9.0 kW × 300 hours × £0.277 = £749.70 per year

Per Session Cost (1.5 hour session):
9.0 kW × 1.5 hours × £0.277 = £3.74 per session

⚠️ Actual costs depend on usage patterns, session length, insulation quality, and current energy tariffs. The heater cycles on/off to maintain temperature, so actual consumption may be lower than rated power.
