HPGS-V14HW/ HPGS-V16HN

Year-Round Comfort

This heavy-duty split system acts as a central climate engine certified for stable heating in extreme winter climates down to -28°C and high-capacity cooling in summer up to +43°C. Operating on a fully reversible cycle, it delivers chilled water for active fan-coil cooling or underfloor cooling during peak summer heat. Managed by SENSEI's advanced DC inverter control, the system regulates water temperature delivery with a precise accuracy of 0.5°C, preventing sudden temperature drops or uncomfortable thermal swings.

Technical Advantages & Features

• Top-Tier Seasonal Efficiency (A+++ Class): Powered by advanced DC inverter technology, the system extracts up to 75% of its total thermal output from the ambient outdoor air, minimizing seasonal utility costs even under demanding winter conditions.

• Freeze-Safe Split Design: All water-carrying hydraulic connections and components are safely housed inside the indoor hydro-module (HPGS-V14HW). This completely eliminates any risk of external pipe bursts or freezing during unexpected winter power grid outages.

• Premium Twin-Rotary DC Compressor: Houses a high-capacity inverter compressor with enhanced acoustic blankets, delivering low-vibration, whisper-quiet performance despite its high output.

• Ozone-Safe R32 Refrigerant: Fully optimized to run on next-generation R32 refrigerant, which increases thermodynamic heat transfer efficiency by 10% and has a lower global warming potential (GWP) compared to older systems.

• Color Touchscreen Controller: Features an integrated wired touchscreen controller to program complex weather-dependent heating curves, vacation modes, and DHW sanitization cycles.

Installation & Operation Insights

• From our engineering teams' experience: For a powerful system like the HPGS-V14HW / HPGS-V16HN, a properly sized buffer tank (typically 80 to 100 liters) is highly recommended to ensure smooth defrost cycles and prevent compressor short-cycling.

• We mount the heavy outdoor unit on reinforced floor-standing platforms with industrial-grade rubber vibration-damping mounts to completely isolate mechanical hum from the building's structural walls. Since the connection between the indoor hydro-module and outdoor unit relies exclusively on copper refrigerant line sets (3/8" liquid and 5/8" gas), no water pipes run outdoors, making the system inherently freeze-proof.

Best Suited For:

• Owners of spacious private houses and cottages (120–150 m²) who want to transition away from traditional gas or solid-fuel boilers to a high-efficiency green energy system.

• Properties with extensive underfloor heating loops and domestic hot water demands, where consistent, high-capacity flow rates are required.

Might Not Be Suited For:

• If your home's total heated area is well under 100 m², the 14.0 kW capacity will be oversized and can lead to inefficient compressor cycling; in this case, the HPGS-V10HW / HPGS-V12HN or HPGS-V8HW / HPGS-V8HN is a much more balanced choice.
