📏 Room Sizing Guide

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

Tylö Sense Sport Combi 4 Coverage: With 4.5 kW output, this heater is specifically designed for compact sauna rooms between 2-4 m³.

Adjustment Factors:

Condition	Adjustment
Glass door or windows	Add 1.2-2 m³ per m² of glass
Uninsulated log walls	Add 25-50% to calculated volume
Stone, tile or glass walls	Add 1.2-2 m³ per m² of hard surface
Outdoor/barrel sauna	Add 25-30% to calculated volume
High ceiling (above 2.1m)	Add proportional extra volume

Worked Example: 📍 Small En-Suite Sauna: 1.5m × 1.2m × 1.9m

• Base volume: 3.42 m³
• Glass door (0.6m × 1.8m = 1.08 m²): +1.6 m³
• Total calculated: 5.02 m³
• With 4.5 kW Sense Sport Combi 4: ✅ Suitable with good insulation

⚠️ Note: Minimum ceiling height of 1900 mm and maximum of 2100 mm required for proper installation.

💷 Running Costs

Energy Rate Used: 26.35p/kWh (Ofgem Price Cap Q4 2025)

Annual Cost Estimates:

Usage Level	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	2	150	£178
🏠 Regular Use	4	300	£356
🧖 Heavy Use	6	450	£533

Calculation Formula:

Annual Cost = kW × Hours/Year × £0.2635

Example (Regular Use):
4.5 kW × 300 hours × £0.2635 = £355.73

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

💡 The Split Output technology can reduce actual consumption by up to 30%, potentially lowering these costs further. Actual costs depend on usage patterns, session length, and current energy rates.

❓ Frequently Asked Questions

Q: What size room will this heater work for? A: The Tylö Sense Sport Combi 4 is specifically designed for compact sauna rooms between 2 and 4 m³. For rooms with glass doors, uninsulated walls, or hard surfaces like tile, add 1.2-2 m³ per square metre of these materials to your calculation.

Q: How long does it take to heat up? A: Typically 30-45 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: You have two options: 400-415V 2N~ supply with 10A circuit and 1.5mm² cable, or 200-240V 1N~/2~ supply with 20A circuit and 4mm² cable. A dedicated circuit with multi-pole isolation is required. Professional installation by a qualified electrician is mandatory.

Q: Are sauna stones included? A: No, stones are sold separately. You will need approximately 7 kg of dolerite/diabase sauna stones (30-50mm diameter). We recommend Tylö brand sauna stones for optimal performance and warranty compliance.

Q: Can I use this for steam only? A: Yes, the Sense Sport Combi 4 offers full steam bath functionality via the built-in steam generator. Fill the water reservoir through the herb grille and activate the steam function. One heating element operates during steam mode to prevent excessive current draw.

Q: How do I maintain the steam function? A: Empty the water reservoir after each use to prevent limescale buildup. Descale periodically using Tylö Solvent descaling agent. After steam sessions, raise temperature to 80°C for 20 minutes to dry the cabin.

Q: What is the warranty? A: Contact Parts4Tubs for full warranty terms and conditions.

Q: Can I install this outdoors? A: This heater is designed for indoor installation only. The sauna cabin must provide proper insulation and protection from the elements.
