📐 Compatible Heater Sizing Guide

The Harvia Xenio CX110 is designed to control sauna heaters up to 11 kW. Use the following guidelines to determine which heaters are compatible:

Basic Formula:

1 kW heater power ≈ 1 - 1.5 m³ sauna room volume

Compatible Heater Power Range:

Heater Power	Typical Room Size	Suitable For
2.3 – 4.5 kW	2 – 6 m³	Small home saunas, 1-2 people
4.5 – 6 kW	5 – 8 m³	Medium home saunas, 2-3 people
6 – 8 kW	7 – 12 m³	Family saunas, 3-4 people
8 – 11 kW	10 – 16 m³	Large family/small commercial, 4-6 people

Adjustment Factors:

Condition	Adjustment
Glass door/windows	+1.5 m³ per m² of glass
Uninsulated/log walls	+25-50% to calculated volume
Outdoor/barrel sauna	+25-30% to calculated volume
High ceiling (>2.3m)	Add extra volume proportionally

Worked Example:

📍 Room: 2m × 2m × 2.2m = 8.8 m³ base volume
📍 Glass door (0.8m × 2m = 1.6 m²): +2.4 m³
📍 Total effective volume: 11.2 m³
📍 Recommended heater: 8-9 kW
📍 CX110 compatible: ✅ Yes (within 11 kW limit)

💡 Note: For heaters above 11 kW (up to 17 kW), the optional LTY17 Power Extension Unit can be added to the system.

💷 Running Cost Considerations

While the CX110 is a control panel rather than a heater, understanding running costs helps you plan your sauna installation.

Current UK Energy Rate: £0.245/kWh (Ofgem Price Cap, October 2024 – Direct Debit customers)

Estimated Annual Running Costs by Heater Size:

Heater Power	Light Use (2×/week)	Regular Use (4×/week)	Heavy Use (6×/week)
6 kW	£220	£441	£661
8 kW	£294	£588	£882
9 kW	£331	£661	£992
11 kW	£404	£809	£1,213

Calculation basis: 1.5 hour sessions, 150/300/450 hours annually

Per Session Cost Examples:

• 6 kW heater × 1.5 hours × £0.245 = £2.21 per session
• 9 kW heater × 1.5 hours × £0.245 = £3.31 per session
• 11 kW heater × 1.5 hours × £0.245 = £4.04 per session

⚠️ Actual costs depend on heater efficiency, insulation quality, session length, and current energy tariffs.
