📐 Heater Sizing Guide

The Harvia Xenio CX170 is compatible with electric sauna heaters from 2.3 kW to 17 kW. When selecting a compatible heater, use the standard sizing formula:

Basic Formula:

1 kW = 1 - 1.5 m³ sauna room volume

Adjustment Factors:

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

Worked Example:

📍 Example Room: 2.5m × 2m × 2.2m
- Base volume: 11 m³
- Glass door (0.8m × 2m = 1.6 m²): +2.4 m³
- Total calculated: 13.4 m³
- Recommended heater: 10-14 kW
- CX170 capacity: ✅ Suitable (controls up to 17 kW)

💷 Running Costs (Indicative)

Energy Rate Used: £0.245/kWh (UK average based on Ofgem price cap)

The running costs below are for typical sauna heaters controlled by the CX170. Actual costs depend on your heater’s power rating, usage patterns, and current energy rates.

Example: 9 kW Heater Controlled by CX170

Usage Level	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	2	150	£331
🏠 Regular Use	4	300	£662
🧖 Heavy Use	6	450	£993

Calculation Formula:

Annual Cost = Heater kW × Hours/Year × £0.245

Example (9 kW heater, Regular Use):
9 kW × 300 hours × £0.245 = £661.50

Per session cost: Approximately £3.31 per 1.5 hour session

⚠️ Actual costs depend on your heater’s power rating, usage patterns, session length, and current energy rates.
