📐 Room Sizing Guide

Basic Sizing Principle: As a general guideline, allow 1 kW of heating power for every 1-1.5 m³ of sauna room volume.

The Tylö Sense Commercial 6 with its 6.6kW output is optimised for sauna rooms between 4 and 8 m³ under standard conditions. However, various factors can affect heating requirements:

Adjustment Factors:

Condition	Adjustment
Glass door or windows	Add 1.5 m³ per m² of glass
Uninsulated or log walls	Add 25-50% to base volume
Plastered ceiling or walls	Add 1.2-2.0 m³ per m²
Brick walls without insulation	Increases heat-up time significantly
High ceiling (above 2.3m)	Add extra volume allowance

Worked Example:

📍 Example Commercial Sauna Room: 2.0m × 1.5m × 2.2m

• Base volume: 6.6 m³
• Glass door panel (0.8m × 2m = 1.6 m²): Add 2.4 m³
• Total calculated volume: 9.0 m³
• Recommendation: At 9 m³, consider the Sense Commercial 8 (8kW) for optimal performance, or ensure excellent insulation if using the 6.6kW model

📍 Ideal Room for Sense Commercial 6: 1.8m × 1.4m × 2.1m

• Base volume: 5.3 m³
• Standard insulated construction with no glass
• ✅ Perfect match for 6.6kW heater (4-8 m³ range)

💷 Running Costs

Energy Rate Used: £0.2635/kWh (Ofgem Price Cap October-December 2025)

The Tylö Sense Commercial 6 features Split Output technology, which can reduce energy consumption by up to 30% once the desired temperature is reached. The calculations below show costs based on full power operation; actual costs may be lower.

Annual Cost Estimates:

Usage Level	Sessions/Week	Hours/Year	Annual Cost (Est.)
🏠 Light Commercial Use	3	225	£391
🧖 Regular Commercial Use	5	375	£652
🏋️ Heavy Commercial Use	7	525	£913

Calculation Formula:

Annual Cost = kW × Hours/Year × £0.2635

Example (Regular Use):
6.6 kW × 375 hours × £0.2635 = £652 per year

Per Session Cost (1.5 hour session):
6.6 kW × 1.5 hours × £0.2635 = £2.61 per session

💡 Energy Saving Tip: With Split Output technology actively reducing power once temperature is achieved, real-world costs are typically 20-30% lower than these maximum estimates.

⚠️ Actual costs depend on usage patterns, session length, room insulation, and current energy tariffs. Costs calculated using Ofgem-verified rates as of Q4 2025.

⚡ Installation Requirements

⚠️ IMPORTANT: This is a commercial heater unit ONLY. It requires a separate relay power unit (RB Commercial or RB Commercial Lite) and control panel (Pure or Elite) to function. This separation of electronics from the heating unit is mandatory for commercial installations. Installation must be carried out by a qualified electrician in accordance with BS 7671 (IET Wiring Regulations) and local building codes.

Electrical Requirements

Supply Type	Voltage	Amperage	Fuse Size	Cable Size
Single Phase	200-208V~	33 A	40 A	10 mm²
Single Phase	230-240V~	29 A	32 A	10 mm²
Three Phase	200-208V 3~	19 A	20 A	4 mm²
Three Phase	230V 3~	17 A	20 A	4 mm²
Three Phase	400-440V 3~	10 A	16 A	1.5 mm²
Three Phase	400-415V 3N~	10 A	16 A	1.5 mm²

Minimum Clearances

Position	Distance
Side walls	110 mm minimum
Back wall (with optional legs)	95 mm minimum
Ceiling	1030 mm minimum
Benches/Interior fittings (front)	100 mm minimum
Interior fittings (sides)	30 mm minimum
Floor (wall-mounted)	270 mm
Floor (with optional legs)	100 mm
Minimum ceiling height	1900 mm

Ventilation Requirements

• Fresh air intake: Position directly below the heater centreline, through the wall. Minimum size 125 cm² for standard installations
• Exhaust vent: Position at maximum distance from intake (diagonally opposite), high on the wall or in the ceiling. Must have equal area to intake vent
• Critical: Exhaust must NOT vent directly outdoors (reverses airflow direction affecting temperature protection)

Sensor Positioning

• Position 1: 300 mm from the heater body
• Position 2: 300 mm from the heater front
• Height: 150 mm from ceiling
• Note: For walls of highly heat-absorbing materials (concrete, brick, hardened glass), the sensor may be ceiling-mounted 300 mm from the heater centreline

❓ Frequently Asked Questions

Q: What size room will this heater work for? A: The Tylö Sense Commercial 6 (6.6kW) is designed for sauna rooms between 4 and 8 m³. For rooms with glass doors, uninsulated walls, or plastered surfaces, add 25-50% to your base volume calculation. Rooms larger than 8 m³ should consider the Sense Commercial 8 (8kW) model.

Q: Why is this called a “Commercial” heater? A: Commercial sauna regulations typically require that electronic controls are housed separately from the heating unit. The Sense Commercial range is designed specifically for this requirement, with the control panel and relay box installed outside the sauna cabin. This is not suitable as a standalone purchase for new installations without the complete control system.

Q: Can I use this for a home sauna? A: While technically possible if you purchase the full control system (relay box and control panel), for most domestic installations the Tylö Sense Sport or Sense Elite ranges offer a more cost-effective solution with integrated controls. The Commercial range is primarily designed for public and commercial facilities.

Q: How long does it take to heat up? A: Heat-up times vary depending on room size, insulation quality, and outside temperature. For a well-insulated 6 m³ sauna room, expect approximately 30-45 minutes to reach optimal bathing temperature (80-90°C).

Q: What electrical supply do I need? A: Multiple options are available. For UK installations, 230-240V single-phase (29A, 10mm² cable) or 400V three-phase (10A, 1.5mm² cable) are most common. A dedicated circuit with appropriate fuse protection is required. Professional installation by a qualified electrician is mandatory.

Q: Are sauna stones included? A: No, stones are sold separately. The Sense Commercial 6 accepts up to 20 kg of sauna stones. We recommend Tylö genuine black diabase or vulcanite stones, available from Parts4Tubs.

Q: What is the warranty? A: Contact Parts4Tubs for full warranty terms and conditions. Warranty requires professional installation by a qualified electrician and adherence to all installation guidelines.

Q: Can I install this outdoors? A: The Sense Commercial 6 is designed for indoor sauna cabin installation only. The heater and all control components must be protected from direct weather exposure.

Q: What control panel should I choose? A: For maximum features including WiFi remote control and smartphone app connectivity, choose Elite Cloud. For reliable digital control without WiFi, choose Pure. For simple mechanical operation and replacement of existing installations, the TS 30-012 or TS 30-6 panels are suitable.
