📏 Room Sizing Guide

Basic Formula:

1 kW ≈ 1 – 1.5 m³ sauna room volume

Adjustment Factors:

Condition	Adjustment
Glass door/windows	+1.2 – 2 m³ per m² of glass
Uninsulated/log walls	+25 – 50% to volume
Stone/tile/glass walls without insulation	+1.2 – 2 m³ per m²
Outdoor installation	+25 – 30% to volume
High ceiling (above 2.1m)	Additional volume calculation required

Worked Example:

📍 Example Room: 1.5m × 1.2m × 2.0m
   Base volume: 3.6 m³

   Glass door (0.7m × 1.9m = 1.33 m²): +2.0 m³
   Total calculated: 5.6 m³

   This 4.5 kW heater at maximum output: Suitable for 2-4 m³
   Result: Consider next size up for rooms with extensive glass

Power Selection Guide:

Power Setting	Ideal Room Size	Best For
2.2 kW	2 – 2.5 m³	Very compact saunas, single-person cabins
4.5 kW	2 – 4 m³	Small family saunas, bathroom conversions

⚠️ Important: The minimum room volume must not be exceeded, and the maximum volume must not be exceeded. Undersized heaters struggle to reach temperature; oversized heaters can cause uncomfortable hot spots.

💷 Running Costs

Energy Rate Used: £0.2635/kWh (UK average Direct Debit rate – Ofgem Q4 2025)

Cost Calculation at 4.5 kW (maximum power):

Usage Level	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	1	75	£89
🏠 Regular Use	2	150	£178
🧖 Moderate Use	3	225	£267
🧖 Heavy Use	5	375	£445

Calculation Formula:

Annual Cost = kW × Hours/Year × £0.2635

Example (4.5 kW heater, Regular Use – 2 sessions weekly):
4.5 kW × 150 hours × £0.2635 = £178/year

Per session cost (1.5-hour session at 4.5 kW):
4.5 kW × 1.5 hours × £0.2635 = £1.78 per session

Cost Savings with Split Output Technology: The Sense Sport 2/4’s intelligent Split Output system can reduce consumption by up to 30% once your sauna reaches the desired temperature, potentially lowering annual costs to approximately £125 for regular use.

Usage at 2.2 kW Setting	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	1	75	£43
🏠 Regular Use	2	150	£87

⚠️ Actual costs depend on usage patterns, session length, room insulation, and current energy rates. Rates verified against Ofgem Price Cap for October-December 2025.

❓ Frequently Asked Questions

Q: What size room will this heater work for? A: The Sense Sport 2/4 operates at two power levels. At 2.2 kW, it suits rooms of 2-2.5 m³. At 4.5 kW, it heats rooms between 2-4 m³. For rooms with glass doors or uninsulated walls, add 1.2-2 m³ per square metre of these surfaces to your calculation.

Q: How long does it take to heat up? A: Typically 20-30 minutes to reach optimal temperature of 60-90°C, depending on room size, insulation quality, and ambient temperature.

Q: What electrical supply do I need? A: This depends on your power setting. The 2.2 kW setting requires 200-240V with a 10A circuit. The 4.5 kW setting can use either 400V 2-phase with 10A, or 230V single-phase with a 20A circuit. Professional installation by a qualified electrician is mandatory.

Q: Are sauna stones included? A: No, stones are sold separately. The heater requires 7 kg of dolerite/diabase sauna stones (30-50 mm diameter). We recommend TylöHelo branded stones for optimal performance and warranty compliance.

Q: What is the warranty? A: TylöHelo products carry a manufacturer warranty. Contact Parts4Tubs for specific warranty terms and conditions applicable to your purchase.

Q: Can I install this outdoors? A: The heater is designed for indoor sauna cabins. For outdoor pod or cabin saunas, ensure the sauna structure itself provides full weather protection. The exhaust vent must never lead directly outdoors.

Q: Is this a replacement for the Tylö Compact 2/4? A: Yes, the Sense Sport 2/4 is the direct replacement for the discontinued Tylö Compact 2/4, offering enhanced features including Split Output technology and improved efficiency.

Q: How often should I check the stones? A: Check the stone compartment at least once annually, or as many times per year as you use the heater per week. For example, using the sauna 3 times weekly means checking stones 3 times yearly.
