🏠 Real World Applications

🛁 Heated Whirlpool Bath Systems

The G70-2HN-S excels in whirlpool bath installations where cold air injection would compromise bathing comfort. The 250W heater warms incoming air during start-up, ensuring a pleasant bubble experience from the first moment. Ideal for bathroom installations where ambient temperatures may be cool.

♨️ Medium-Sized Hot Tub Installation

With 700W motor power delivering robust airflow, this blower suits medium-sized hot tubs requiring heated air massage. The electronic control integration allows seamless operation through existing spa panels, while the heater maintains comfortable air temperatures even in cooler installation environments.

🔄 Heated Blower Replacement

A direct replacement for worn or failed heated blowers in existing spa systems. The standard 1½” BSP union and 32mm connection ensure compatibility with most plumbing configurations. Electronic PCB control allows integration with modern spa control systems.

💆 Enhanced Hydrotherapy Systems

The combination of powerful airflow and heated air delivery creates superior hydrotherapy conditions. Variable speed compatibility allows users to adjust bubble intensity while maintaining warm, comfortable air injection for muscle relaxation and therapeutic benefit.

🏢 Professional Wellness Installations

Suitable for professional whirlpool bath installations in hotels, wellness centres, and day spas where client comfort is paramount. The heated airflow eliminates the cold-air complaints common with non-heated blowers, improving the overall guest experience.

🔧 Installation Considerations

⚠️ Professional Installation Required – All electrical work must be carried out by a qualified electrician according to national wiring regulations.

Electrical Requirements:

• Supply: 230–240V / 50Hz
• Current draw: 4.1A (total for motor and heater)
• 1m cable with bare-end termination
• Requires fixed wiring switch with minimum 3mm contact separation in each pole
• Class I (earthed) or Class II wiring configurations available
• Integrated PCB for connection to spa control panels or Genesis touchpads

Mounting & Positioning:

• Suitable for mounting below whirlpool baths and spas
• Secure using three screws through the rubber feet
• Must not be accessible to bathers without use of a tool
• Requires well-ventilated location for optimal heater performance
• Position in warmer areas where possible to maximise heating efficiency
• Ensure accessibility for future inspection and maintenance

Backflow Prevention (Critical):

• Install either a double air loop with one check valve, OR two check valves, above maximum water level
• Recommended: 32mm check valve to prevent backflow and reduce noise
• Pipe/hose system must be securely fixed to the blower outlet

Connection Details:

• Outlet: Rotatable 1½” BSP threaded union included
• 32mm tail-piece for flexible hose connection
• Union must be securely fitted to prevent air leaks

Heater Safety Information:

• Heating element automatically cuts out when air temperature exceeds approximately 50°C
• Per EN60335-2-60: Water temperature at bath inlet must not exceed 50°C when heater is active
• Heater designed to reduce cold air during start-up, not to continuously heat water

Thermal Protection Note: If the thermal protection activates, the blower will not restart until power is disconnected and reconnected AFTER the blower has cooled to room temperature.
