📏 Room Sizing Guide

Basic Sizing Formula: 1 kW = approximately 1-1.5 m³ of well-insulated sauna room volume

Adjustment Factors:

Condition	Adjustment
Glass door or windows	Add 1.2-1.5 m³ per m² of glass
Uninsulated/log walls	Multiply volume by 1.5
Outdoor/garden sauna	Add 25-30% to calculated volume
High ceiling (above 2.3m)	Add additional volume allowance
Tile or concrete surfaces	Add 1.2 m³ per m² of exposed surface

Worked Example:

📍 Example Room: 2.0m × 1.5m × 2.1m (length × width × height)

• Base volume: 6.3 m³
• Glass door (0.7m × 1.9m = 1.33 m²): +1.6 m³
• Total calculated volume: 7.9 m³
• This 6.0kW heater rated for 5-8 m³: ✅ Ideal match

The Harvia Wall SW60E is perfect for this configuration, providing efficient heating with capacity to spare for steam production.

💷 Running Costs

Energy Rate Used: £0.245/kWh (UK Ofgem Price Cap rate, January-March 2026)

Estimated Annual Running Costs:

Usage Level	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	2	150	£220.50
🏠 Regular Use	4	300	£441.00
🧖 Heavy Use	6+	450	£661.50

Cost Calculation Formula:

Annual Cost = Power (kW) × Hours/Year × £0.245/kWh

Example (6.0kW heater, Regular Use - 4 sessions weekly):
6.0 kW × 300 hours × £0.245 = £441.00 per year

Per Session Cost (1.5 hour session):
6.0 kW × 1.5 hours × £0.245 = £2.21 per session

⚠️ Actual costs depend on your energy tariff, session duration, room insulation quality, and ambient temperature. The heater cycles on/off to maintain temperature, so actual consumption may be lower than rated power suggests.

❓ Frequently Asked Questions

Q: What size room will this heater work for? A: The Harvia Wall SW60E is rated for sauna rooms between 5.0 and 8.0 cubic metres. For rooms with glass doors, uninsulated surfaces, or outdoor installations, add 25-50% to your base volume calculation when selecting heater size.

Q: How long does it take to heat up? A: A well-insulated sauna room of appropriate size typically reaches bathing temperature (65-80°C) within 45-60 minutes, depending on ambient temperature and insulation quality.

Q: What electrical supply do I need? A: This heater can operate on 230V single-phase (requiring 35A fuse and 3 × 10mm² cable) or 400V three-phase (requiring 3 × 10A fuses and 5 × 1.5mm² cable). A dedicated circuit and professional installation by a qualified electrician are mandatory.

Q: Are sauna stones included? A: No, sauna stones are sold separately. This heater requires up to 20kg of suitable sauna stones with 5-10cm diameter. Olivine diabase or peridotite stones are recommended.

Q: What is the warranty? A: Harvia provides a 2-year warranty for domestic/family use and 1-year warranty for communal residential use. Registering your heater with Harvia within 3 months of purchase extends the domestic warranty by an additional year (Finland only; check local terms).

Q: Can I install this heater myself? A: No. UK regulations require all fixed electrical installations to be carried out by a qualified electrician. The heater must be connected in accordance with BS 7671 and local building regulations.

Q: Is this heater suitable for outdoor use? A: The heater itself is designed for interior wet-area use. It can be installed in an outdoor sauna cabin provided the cabin provides adequate weather protection and maintains minimum operating temperatures. Storage below -5°C may trip the overheat protector.

Q: Why does this model require a separate control unit? A: The “E” designation indicates External control. This design allows greater flexibility—you can position the control panel conveniently outside the sauna, and the heater can be installed under benches or in locations where built-in controls would be impractical.
