📐 Room Sizing Guide

Basic Formula:

1 kW = approximately 1 – 1.5 m³ sauna room volume

Adjustment Factors:

Condition	Adjustment
Glass door or windows	Add 1.2 m³ per m² of glass
Uninsulated or log walls	Multiply total volume by 1.5
Outdoor or barrel sauna	Add 25-30% to calculated volume
Ceiling height over 2.3 m	Add extra volume accordingly

Worked Example:

📍 Example Room: 2.0 m × 1.8 m × 2.2 m

• Base volume: 7.92 m³
• Glass door (0.8 m × 2.0 m = 1.6 m²): Add 1.92 m³
• Total calculated volume: 9.84 m³
• This 6.8 kW Cilindro heater: ✅ Suitable (rated for 6-10 m³)

📍 Log Cabin Sauna Example: 2.0 m × 1.5 m × 2.1 m

• Base volume: 6.3 m³
• Log wall multiplier: 6.3 × 1.5 = 9.45 m³
• Adjusted volume: 9.45 m³
• This 6.8 kW Cilindro heater: ✅ Suitable (within 6-10 m³ range)

⚠️ If your calculated volume exceeds 10 m³, consider the larger 9.0 kW Cilindro PC90XE model.

💷 Running Costs

Energy Rate Used: £0.2769/kWh (Ofgem Price Cap Q1 2026 – Direct Debit average)

Cost Calculation:

Usage Level	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	2	150	£282
🏠 Regular Use	4	300	£565
🧖 Heavy Use	6	450	£847

Calculation Formula:

Annual Cost = kW × Hours/Year × £0.2769

Example (6.8 kW heater, Regular Use):
6.8 kW × 300 hours × £0.2769 = £565 per year

Per session cost (1.5 hour session):
6.8 kW × 1.5 hours × £0.2769 = £2.82 per session

💡 Energy Saving Tip: The heater cycles on and off to maintain temperature once heated, so actual consumption is typically 60-70% of the rated power during a session.

⚠️ Actual costs depend on usage patterns, session length, room insulation, and current energy rates. Rates shown are Ofgem Price Cap averages for January-March 2026.

🪨 Sauna Stones

Stone Requirements:

• Recommended Quantity: 80 kg (maximum capacity 90 kg)
• Recommended Stone Size: 5-10 cm diameter
• Stones Included: No – sold separately
• Recommended Types: Olivine diabase, peridotite, or olivine

Important Stone Guidelines:

• Use only stones specifically designed for sauna heaters with broken/angular surfaces
• Do NOT use ceramic “stones” or soft soapstone – these do not absorb sufficient heat and may damage heating elements
• Rinse stones to remove dust before installation
• Stack stones loosely in the centre and tightly against the outer grate to prevent direct heat radiation
• Inspect and re-stack stones at least once per year; replace crumbled or damaged stones
• Stones settle most rapidly during the first two months of use

⚠️ Using stones not recommended by Harvia will void the warranty.
