Polytropic
HRS heat pump | Elite R290-Inverter XS | 9.20 ~ 6.90 kW | 230 V - Polytropic
€2.899,00
Sustainable and future-proof pool heating
The Polytropic HRS Elite R290-Inverter XS is a modern pool heat pump that combines powerful performance with maximum energy efficiency. Thanks to full-inverter technology and the natural refrigerant R290 (propane), this heat pump delivers high efficiency with minimal environmental impact.
The use of R290 ensures a very high COP and also makes the heat pump future-proof for F-Gas regulations.
Exceptional energy efficiency
The combination of inverter technology and natural refrigerant ensures particularly low energy consumption.
Benefits:
• Very high COP for maximum energy savings
• Full-inverter power control
• Environmentally friendly R290 refrigerant
• Housing made from recycled materials
• Compatible with solar panels via PolySolar Energy System
Ideal for use with solar panels
The heat pump can be integrated with the PolySolar Energy System, allowing the energy consumption to be partially or fully covered by solar energy.
Benefits:
• Up to 100% energy supply via solar panels possible
• Less dependent on the electricity grid
• Maximum energy savings
Whisper-quiet and intelligently controlled
The Elite R290-Inverter XS is designed for stable and quiet operation under all conditions.
Technology:
• 2D inverter technology for precise power control
• DC brushless fan with variable speed
• PolySmart Control for automatic power control
• Sound insulation for extremely quiet operation
Reliable operation at low temperatures
Thanks to the advanced low-temperature system, the heat pump continues to operate efficiently, even in cold weather.
Features:
• Smart defrost system via cycle reversal
• Compressor preheating
• Antifreeze condensate system
• Fully automatic control of all functions
Smart operation and connectivity
The heat pump is equipped with modern controls and monitoring.
Features:
• Colour touchscreen
• 3 operating modes: heating, cooling and automatic
• PolyConnect WiFi + 4G connectivity
• Smartphone control
• Real-time monitoring and diagnostics
Power Boost mode
With the Power Boost mode, the pool reaches the desired temperature faster.
Benefits:
• Up to 20% faster heating
• Shorter start-up time
• Immediate comfortable swimming water
Refrigerant pressure monitoring
An integrated sensor continuously monitors the refrigerant pressure for optimal performance and maintenance.
Benefits:
• Optimisation of water flow and COP
• Precise control of the heat pump and filtration
• Faster diagnostics during maintenance
Included
• Winter cover
• Hydraulic connections Ø 50 mm
• 4 vibration dampers (silent blocks)
• Condensate drain set
