📏 Room Sizing Guide

General Sizing Principle: Allow 1 kW per 1 to 1.5 m³ of sauna room volume.

The Tylö Sense Combi Pure 10.5kW is designed for sauna rooms between 10 and 18 m³ under standard conditions.

Adjustment Factors:

Condition	Adjustment
Glass door or windows	Add 1.5 m³ per m² of glass
Uninsulated or log walls	Add 25-50% to calculated volume
Concrete, brick or plastered surfaces	Add 1.2-2 m³ per m² of uninsulated surface
High ceiling (above 2.3m)	Calculate additional volume accordingly
Outdoor or barrel sauna	Add 25-30% to base volume

Worked Example:

📍 Example Room: 2.5m × 2.5m × 2.2m

• Base volume: 13.75 m³
• Glass door (0.8m × 2m = 1.6 m²): +2.4 m³
• Total calculated: 16.15 m³
• This 10.5kW heater: ✅ Suitable (rated for 10-18 m³)

📍 Borderline Example: 3m × 2.5m × 2.1m

• Base volume: 15.75 m³
• Glass window (0.5 m²): +0.75 m³
• Log walls: +25% = 4.13 m³
• Total calculated: 20.63 m³
• This 10.5kW heater: ⚠️ May be undersized – consider next model up or improve insulation

💷 Running Costs

Energy Rate Used: £0.27/kWh (Ofgem Price Cap, December 2025)

Usage Level	Sessions/Week	Hours/Year	Annual Cost	Per Session
🏠 Light Use	2	150	£425	£2.84
🏠 Regular Use	4	300	£851	£2.84
🧖 Heavy Use	6	450	£1,276	£2.84

Calculation Formula:

Annual Cost = kW × Hours/Year × £0.27

Example (Regular Use – 4 sessions per week):
10.5 kW × 300 hours × £0.27 = £850.50 per year

Per session cost (1.5 hour session):
10.5 kW × 1.5 hours × £0.27 = £4.25 at full power
With Split Output (30% saving): approximately £2.98 per session

💡 Energy Saving Note: The Split Output technology significantly reduces actual consumption. Once your sauna reaches target temperature, the heater automatically reduces power, meaning real-world costs are typically 20-30% lower than maximum calculations suggest.

⚠️ Actual costs depend on usage patterns, session length, room insulation, and current energy rates. Rates updated quarterly – check Ofgem for latest pricing.

❓ Frequently Asked Questions

Q: What size room will this heater work for? A: The Tylö Sense Combi Pure 10.5kW is designed for sauna rooms between 10 and 18 m³. For rooms with glass doors, uninsulated walls, or outdoor installations, add 25-50% to your calculated volume when sizing.

Q: How long does it take to heat up? A: Typically 25 minutes to reach 80°C operating temperature, depending on room size, insulation quality, and ambient temperature. The twin side air chamber design ensures exceptionally fast, even heat distribution.

Q: What electrical supply do I need? A: This 10.5kW model requires a three-phase supply – either 400-415V 3N~ (16A, 2.5mm² cable) or 230V 3~ (28A, 10mm² cable). Single-phase installation is not approved for this power rating in Europe. Professional installation by a qualified electrician is required.

Q: Are sauna stones included? A: No, stones are sold separately. You will need approximately 20kg of suitable sauna stones, sized 30-60mm diameter. We recommend genuine Tylö diabase stones for optimal performance and longevity.

Q: Can I use this for both dry sauna and steam? A: Yes – this is a combi heater offering both traditional dry sauna and steam functionality. The integrated water reservoir produces steam when filled, whilst dry sauna mode operates without water. You can adjust the balance between temperature and humidity using the Pure control panel.

Q: What is the Split Output feature? A: Split Output is Tylö’s intelligent energy-saving technology. During heat-up, all three heating elements operate at full power. Once your target temperature is reached, the heater automatically reduces to economy mode, maintaining temperature with lower energy consumption – typically saving up to 30%.

Q: Can I install this outdoors? A: The heater is designed for installation inside a properly constructed sauna cabin. For outdoor/garden saunas, the heater must be installed within the insulated cabin structure with appropriate ventilation. The heater itself should not be exposed to weather.

Q: What warranty is provided? A: Full manufacturer’s warranty applies. Contact Parts4Tubs for detailed warranty terms and conditions.

Q: How do I maintain the steam function? A: Empty and drain the water reservoir after each use to prevent limescale build-up. Descale periodically using Tylö Solvent descaling agent. Clean electrodes with a soft cloth if deposits form. Never use salt water.
