🔥 Harvia Cilindro 9kW Stainless Steel Floor-Standing Sauna Heater – 8-14 m³ Capacity

A towering pillar of Finnish craftsmanship holding 80kg of stones for the ultimate löyly experience

♨️ Product Overview

The Harvia Cilindro 9kW is a striking floor-standing pillar heater that redefines sauna aesthetics whilst delivering exceptional performance. Manufactured by Harvia, Finland’s foremost sauna specialist, this iconic cylindrical design houses an extraordinary 80kg of sauna stones – creating a thermal mass that produces wonderfully soft yet powerful heat for an authentic Nordic bathing experience.

What truly sets the Cilindro apart is its innovative grate-like stainless steel outer shell, which allows bathers to customise their steam experience. Splash water onto the side of the heater for gentle, enveloping steam, or pour directly onto the top of the stone pillar for a sharper, more intense löyly. This model requires a separate control unit, giving you the flexibility to choose your preferred Harvia controller – from basic panels to advanced WiFi-enabled Xenio systems with smartphone app control.

Finished in premium stainless steel and certified to CE and EAC standards, the Harvia Cilindro transforms any sauna into a contemporary wellness sanctuary. Its pillar form factor also offers exceptional installation flexibility, working beautifully as a freestanding feature or embedded within bench structures.

📏 Room Sizing Guide

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: 2.2m × 2.0m × 2.1m
- Base volume: 9.24 m³
- Glass door (0.8m × 2m = 1.6 m²): +2.4 m³
- Total calculated: 11.64 m³
- This 9 kW heater: ✅ Suitable for 8-14 m³ - Ideal match

💡 Tip: The Cilindro’s massive 80kg stone capacity provides excellent heat retention, making it particularly forgiving in rooms with moderate heat loss from glass or ventilation.

💰 Running Costs

Energy Rate Used: £0.2635/kWh (Ofgem Price Cap, October-December 2025)

Cost Calculation:

Usage Level	Sessions/Week	Hours/Year	Annual Cost
🏠 Light Use	2	150	£356
🏠 Regular Use	4	300	£712
🧖 Heavy Use	6	450	£1,067

Calculation Formula:

Annual Cost = kW × Hours/Year × £0.2635

Example (9 kW heater, Regular Use):
9 kW × 300 hours × £0.2635 = £711.45

Per session cost: Approximately £3.56 per 1.5-hour session

⚠️ Actual costs depend on usage patterns, session length, room insulation, and current energy rates. The Cilindro’s large stone mass provides excellent heat retention, potentially reducing overall energy consumption for extended sessions.

Especially Suited For:

• Contemporary sauna designs requiring a visual statement piece
• Installations where adjustable steam character is valued
• Saunas where extended bathing sessions are preferred (exceptional heat retention)
• Bench-embedded installations for seamless integration
• Glass-fronted saunas where the heater becomes a display feature
• Projects requiring advanced digital or WiFi control options

🪨 Sauna Stones

• Stone Capacity: 80 kg (exceptional – approximately 4× typical wall heaters)
• Recommended Stone Size: Ø 5-10 cm
• Stones Included: No – sold separately (80kg required)
• Recommended Types: Peridotite, olivine diabase, olivine, or vulcanite

💡 Why 80kg Matters: The Cilindro’s massive stone capacity creates exceptional thermal mass. This means softer, more consistent heat, abundant steam production, and excellent heat retention even during extended bathing sessions. The large stone volume also allows for the unique soft/sharp steam adjustment the Cilindro is renowned for.

💬 Frequently Asked Questions

Q: What size room will this heater work for? A: The Harvia Cilindro 9kW is designed for sauna rooms between 8 and 14 m³. For rooms with glass doors, windows, or uninsulated walls, add 25-50% to your room volume calculation.

Q: Does this heater come with controls? A: No, this is the “no controls” model. You will need to purchase a separate Harvia control unit. This gives you the flexibility to choose from basic mechanical controllers to advanced WiFi-enabled digital panels.

Q: What makes the Cilindro different from wall-mounted heaters? A: The Cilindro’s pillar design holds 80kg of stones – approximately four times more than typical wall heaters. This creates exceptional thermal mass for softer, more sustained heat and allows for adjustable steam character (soft from the sides, sharp from the top).

Q: How long does it take to heat up? A: A well-insulated sauna room of appropriate size will typically reach bathing temperature (65-80°C) in approximately 45-60 minutes. The large stone mass means slightly longer initial heat-up but superior heat retention thereafter.

Q: Are sauna stones included? A: No, sauna stones are sold separately. You will need 80 kg of suitable sauna stones with diameters between 5-10 cm. We recommend peridotite, olivine diabase, olivine, or vulcanite stones.

Q: Can I control the nature of the steam? A: Yes – this is a unique feature of the Cilindro. Splash water onto the side of the heater through the grate for gentle, soft steam. Pour water directly onto the top of the stone pillar for sharper, more intense löyly.

Q: Which control unit do I need? A: Any compatible Harvia control unit rated for heaters up to 9kW or higher will work. Popular choices include the Harvia C150 for basic control or the Xenio CX110W for WiFi/app functionality. Contact Parts4Tubs for advice on the best option for your needs.

Q: What is the warranty? A: Harvia provides warranty coverage for heaters and control equipment. Family/domestic use typically includes 2 years coverage. Contact Parts4Tubs for full warranty terms applicable to your installation.

Q: Can this heater be embedded in a bench? A: Yes, the Cilindro’s pillar form factor and external control design make it ideal for embedding within bench structures, creating a seamless, integrated appearance. Ensure all minimum clearances are maintained.
