📐 Room Sizing Guide

The HGX110XW covers steam rooms from 6 to 21 m³, making it ideal for larger residential installations and medium-sized commercial facilities. Your actual capacity depends on wall construction and ventilation.

Room Volume by Wall Type

Wall Construction	Not Ventilated	Ventilated
Light wall (acrylic, glass, etc.)	15.0–21.0 m³	10.0–14.5 m³
Tiled light wall	12.0–17.0 m³	8.0–12.0 m³
Tiled stone wall	10.0–14.0 m³	6.0–10.0 m³

Understanding Capacity Variables

• Light walls (acrylic panels, glass enclosures, composite materials) retain heat efficiently for maximum room coverage
• Tiled light walls (ceramic or porcelain on standard substrates) absorb moderate heat during the warm-up phase
• Tiled stone walls (marble, granite, slate, natural stone) absorb significant thermal energy—expect reduced capacity
• Ventilated rooms lose heat continuously through extraction systems, requiring more steam output per cubic metre

Sizing Worked Examples

📍 Example 1: Luxury home spa 3.5m × 3.0m × 2.4m with ceramic tiles

• Base volume: 3.5 × 3.0 × 2.4 = 25.2 m³
• Wall type: Tiled light wall, not ventilated
• HGX110XW capacity: 12.0–17.0 m³
• Result: ❌ Too large – requires HGX150XW or multidrive configuration

📍 Example 2: Hotel wellness suite 3.0m × 2.5m × 2.3m with glass panels

• Base volume: 3.0 × 2.5 × 2.3 = 17.25 m³
• Wall type: Light wall (glass), not ventilated
• HGX110XW capacity: 15.0–21.0 m³
• Result: ✅ Excellent match – comfortably within optimal range

📍 Example 3: Boutique gym steam room 3.0m × 2.0m × 2.4m with tiles and extraction

• Base volume: 3.0 × 2.0 × 2.4 = 14.4 m³
• Wall type: Tiled light wall, ventilated
• HGX110XW capacity: 8.0–12.0 m³
• Result: ⚠️ At upper limit – consider HGX150XW for better performance

📍 Example 4: Residential hammam 2.8m × 2.5m × 2.3m with marble finishes

• Base volume: 2.8 × 2.5 × 2.3 = 16.1 m³
• Wall type: Tiled stone wall, not ventilated
• HGX110XW capacity: 10.0–14.0 m³
• Result: ⚠️ Borderline – HGX150XW recommended for marble installations this size

📍 Example 5: Premium home steam room 3.2m × 2.2m × 2.2m with porcelain tiles

• Base volume: 3.2 × 2.2 × 2.2 = 15.5 m³
• Wall type: Tiled light wall, not ventilated
• HGX110XW capacity: 12.0–17.0 m³
• Result: ✅ Good fit – within comfortable range

💡 Tip: The HGX110XW excels in larger residential projects and commercial applications requiring substantial steam output without the footprint of industrial equipment. For rooms at the upper capacity limits or those with heavy stone finishes, consider the HGX150XW for optimal performance.

💰 Running Costs

Energy Rate Used: £0.245/kWh (UK average – verify current rates at ofgem.gov.uk)

Estimated Running Costs

Usage Pattern	Sessions/Week	Annual Hours	Annual Cost	Cost Per Session
🏠 Light Use	2	~50	£132	£2.65
🏠 Regular Use	4	~100	£265	£2.65
🧖 Heavy Use	6	~150	£397	£2.65

Cost Calculation

Per 30-minute session at full power:
10.8 kW × 0.5 hours × £0.245 = £1.32

Per 60-minute session at full power:
10.8 kW × 1.0 hours × £0.245 = £2.65

⚠️ Actual consumption varies based on room size, insulation quality, ambient temperature, and energy tariff. The generator cycles on and off to maintain set temperature, so real-world usage typically runs 60-80% of rated power once the room reaches operating temperature.

Commercial Value Perspective

For wellness businesses, the HGX110XW delivers exceptional value. At approximately £1.32–£2.65 per session in energy costs, operators can offer premium steam experiences while maintaining healthy margins. The robust construction and commercial-grade warranty provide confidence for intensive daily use.

🛠️ Installation Requirements

Electrical Requirements

Requirement	Specification
Voltage	400V 3N~ (three-phase only)
Fuse Rating	3 × 16 A
Supply Cable	5 × 2.5 mm²
Dedicated Circuit	Required
RCD Protection	Required

Important: The HGX110XW requires a three-phase 400V electrical supply. This is commonly available in UK commercial premises and many residential properties, particularly newer builds, properties with workshops, or those with electric vehicle charging infrastructure. If your property only has single-phase supply, consult a qualified electrician about upgrade options.

Location Requirements

Requirement	Specification
Mounting	Wall mounted (horizontal)
Maximum steam pipe length	10 metres (properly insulated)
Steam pipe specification	15 mm internal diameter copper
Temperature sensor position	Ceiling or wall, 1700–3000 mm above floor
Sensor cable length	5.0 m (supplied)
Control panel cable length	5.0 m (supplied)
Ventilation	Adequate airflow around unit required
Access	Front panel removable for servicing

⚠️ IMPORTANT: Installation must be carried out by a qualified electrician 
and plumber in accordance with BS 7671 (IET Wiring Regulations), 
Water Supply Regulations, and local building codes. Three-phase supply 
with dedicated circuit and RCD protection is mandatory.

💧 Water Requirements

Water Supply

Requirement	Specification
Water pressure	1.5 – 4.0 bar
Connection	G¾” male
Water type	Cold mains supply
Water quality	Soft water recommended

Drainage

Requirement	Specification
Drain connection	G½” female
Drain type	Gravity drain to floor waste
Manual discharge valve	Included as standard
Automatic drain valve	Optional accessory

Water Hardness Guidance

Water Hardness	Recommendation
Soft (below 100 ppm)	Standard operation
Moderately hard (100–200 ppm)	Monitor descaling frequency
Hard (200–300 ppm)	Water softener strongly recommended
Very hard (above 300 ppm)	Water softener essential

At 10.8kW output with high steam production rates, water quality becomes critical. Hard water accelerates limescale formation on heating elements, reducing efficiency and shortening service life. For commercial installations, inline water treatment is considered best practice. A service indicator illuminates after 200 hours of operation, prompting routine maintenance.

🤔 Frequently Asked Questions

Q: What size steam room suits the HGX110XW? A: The HGX110XW covers rooms from 6 to 21 m³, depending on wall materials and ventilation. With glass or acrylic walls and no ventilation, capacity reaches 21 m³. With tiled stone walls, maximum reduces to approximately 14 m³. Refer to the sizing tables for your specific configuration.

Q: Does this model require three-phase power? A: Yes, the HGX110XW operates exclusively on 400V three-phase supply with 3 × 16A fuses. Three-phase is standard in most commercial premises and available in many UK residential properties. Consult a qualified electrician if you’re unsure about your supply.

Q: Is this suitable for commercial use? A: Absolutely. The HGX110XW is designed for both premium residential and commercial applications. Harvia provides a 1-year warranty for commercial installations, and the robust construction handles intensive daily use. Many spas, hotels, and fitness centres specify this model.

Q: How does it compare to the HGX90XW? A: The HGX110XW produces 14.6 kg/h steam versus 12 kg/h from the HGX90XW—approximately 22% more output. This translates to faster warm-up, better temperature stability with door traffic, and suitability for rooms up to 21 m³ versus 17 m³.

Q: Can I control it remotely? A: Yes, all HGX WiFi models include MyHarvia app connectivity. Start sessions remotely, monitor temperature, schedule delay starts, and receive notifications—all from your smartphone.

Q: How long does warm-up take? A: Warm-up time depends on room size and insulation. A typical 12-15 m³ well-insulated room reaches bathing temperature in approximately 15-25 minutes. Larger rooms or those with heavy stone finishes may take slightly longer.

Q: Is a water softener necessary? A: In hard water areas (above 200 ppm), a water softener is strongly recommended. At this power level, scale buildup significantly impacts performance and element longevity. For commercial installations, inline water treatment is considered essential.

Q: What’s included in the delivery? A: The HGX110XW includes the generator unit, Xenio WiFi control panel, temperature sensor (5m cable), steam nozzle, manual discharge valve, and sediment cup. Copper steam pipe (15mm ID) must be sourced separately.

Q: Can multiple generators be linked? A: Yes, up to four Harvia HGX or HGP generators can be connected via multidrive and controlled from a single Xenio panel—ideal for large commercial facilities requiring substantial steam output.

Q: What warranty applies? A: Harvia provides a 2-year warranty for domestic use and 1-year for commercial installations. Warranty requires proper installation and adherence to maintenance schedules per the manual.
