HPGS-V5HW/HPGS-V8HN

Year-Round Comfort

Despite its compact capacity, this system is a robust air-to-air thermodynamic engine certified to deliver stable heating in outdoor temperatures down to -25°C...-28°C and effective cooling up to +43°C. During hot summer days, the system reverses its cycle to supply chilled water for underfloor cooling or fan coils. Managed by a high-precision inverter controller, it keeps water temperature fluctuations within a strict 0.5°C range, eliminating draft sensations and maintaining a perfectly stable microclimate.

Technical Advantages & Features

• Outstanding Seasonal Efficiency (A+++ Class): Utilizing full DC inverter technology, the system maximizes heat transfer from ambient outdoor air (up to 75% free energy extraction), drastically dropping your winter heating costs compared to traditional gas or electric boilers.

• Freeze-Safe Split Design: All water-carrying hydraulic connections and components are safely housed inside the indoor hydro-module (HPGS-V5HW). Even during emergency winter power outages, there is zero risk of external pipe bursts or freezing.

• Premium DC Inverter Compressor: Houses a high-reliability inverter compressor optimized for low-vibration, whisper-quiet operation, keeping the outdoor acoustic footprint to a minimum.

• Eco-Friendly R32 Refrigerant: Fully optimized to run on low-GWP R32 refrigerant, enhancing thermodynamic heat transfer efficiency by 10% and reducing overall system charge requirements.

• Integrated Wired Touch Controller: Comes with an intuitive wired touchscreen panel to program customized weather-dependent heating curves, vacation modes, and DHW sanitization cycles.

Installation & Operation Insights

• From our engineering teams' experience: For the HPGS-V5HW / HPGS-V8HN, installing a buffer tank (typically 30 to 40 liters) is essential to ensure smooth defrost cycles without dropping the indoor system's temperature.

• Because this system relies on standard 1/4" liquid and 1/2" gas copper refrigerant lines connecting the outdoor unit to the indoor hydro-module, installers don't have to worry about routing thick, heavily insulated water mains outdoors. We mount the outdoor unit on reinforced floor stands using industrial-grade rubber vibration dampers to completely isolate any mechanical hum from the living quarters.

Best Suited For:

• Owners of small, highly insulated modern houses or apartments (50–70 m²) who want to run highly economical underfloor heating without the high installation costs of gas pipelines.

• Energy-efficient renovations where low-temperature emitters (underfloor loops or low-temp radiators) are already present.

Might Not Be Suited For:

• If your property exceeds 80–90 m² or suffers from moderate heat losses, the 5.0 kW capacity will be insufficient during peak winter frosts; in this case, upgrading to the HPGS-V8HW / HPGS-V8HN (8.0 kW) or HPGS-V12HW / HPGS-V12HN (12.0 kW) is necessary.
