MONOBLOC R32 DC INVERTER · Air-to-Water Heat Pump

HPGM-14BP (380 V)

Name: HPGM-14BP (380 V)
SKU: HPGM-14BP (380 V)

Cooling: 13.5 kW

Heating: 14,0 kW

The HPGM-14BP (380V) is a heavy-duty, high-output air-to-water monobloc heat pump with a nominal capacity of 14.0 kW, specifically engineered to run on a stable three-phase 380V electrical supply. We recommend this model for spacious modern homes, multi-level townhouses, and light commercial spaces ranging from 120 to 150 m². If your property has three-phase power available and demands robust, consistent heating and domestic hot water (DHW)—but falls just short of requiring a massive 16 kW climate engine—this model is the perfect, highly efficient choice. Because it is a monobloc, all hydraulic components are housed outdoors, saving valuable indoor utility space.

Year-Round Comfort

This three-phase system is designed for reliable year-round performance, certified for stable heating in outdoor temperatures down to -25°C, and highly effective cooling in summer up to +43°C (via underfloor/wall cooling loops or active fan coils). SENSEI's advanced DC inverter control ensures the system maintains target water temperatures with an accuracy of 0.5°C, preventing draft sensations and ensuring stable indoor comfort.

Technical Advantages & Features

Top-Tier Seasonal Efficiency (A+++ Class): The full DC inverter system extracts up to 75% of its thermal energy directly from the ambient air, significantly lowering your seasonal utility bills.
Balanced Three-Phase (380V) Operation: Spreading the electrical load evenly across three phases prevents voltage drops and phase imbalances on local grids, ensuring stable operation during the coldest winter days.
All-in-One Outdoor Concept: The outdoor unit integrates all essential components (high-efficiency plate heat exchanger, DC water pump, expansion vessel, flow switch, and safety valves), delivering a pre-assembled, ready-to-use water heating circuit.
Premium Twin-Rotary DC Compressor: Features a highly reliable inverter compressor with advanced acoustic blankets for whisper-quiet outdoor performance.
Eco-Friendly R32 Refrigerant: Optimized for low-GWP R32 refrigerant, which improves heat transfer efficiency by 10% and reduces the overall refrigerant charge volume.
Wired Touchscreen Controller: Includes an intuitive wired controller to manage complex weather-dependent heating curves, DHW sanitization (Anti-Legionella) cycles, and active scheduling.

Installation & Operation Insights

From our engineering teams' experience: For the three-phase 14 kW model, we highly recommend installing a buffer tank (typically 80 to 100 liters) to guarantee smooth defrost cycles and prevent compressor short-cycling.
Since the monobloc is filled with water and sits entirely outdoors, safeguarding against power grid outages in freezing weather is critical. We strongly advise filling the system with a certified propylene glycol-based thermal fluid or installing specialized mechanical freeze-protection valves (such as Ice-Stop valves).
Installation is straightforward and clean—no on-site refrigerant piping, brazing, or flaring is required. The installer only connects insulated water lines from the outdoor unit to the building's manifold.

Comparison: HPGM-14BP (380V) vs. HPGM-16BP (380V)

While both models share the same heavy-duty three-phase outdoor chassis, choosing between the HPGM-14BP (380V) and the flagship HPGM-16BP (380V) depends on your property's specific size and thermal load.

Feature / Metric	HPGM-14BP (380V)	HPGM-16BP (380V)
Nominal Thermal Capacity	14.0 kW	16.0 kW
Recommended Heating Area	120 – 150 m²	150 – 200 m²
Compressor Power Draw	Lower peak current consumption	Higher peak current consumption
Sub-Zero Output Reserve	Ideal balance for mid-large homes	Maximum thermal output reserve in deep frosts
DHW Recovery Time	Rapid recovery	Maximum speed for very large-volume tanks

Key Takeaways from the Comparison:

Preventing Short-Cycling (Tac-ing): If your home is under 150 m², selecting the HPGM-14BP (380V) is the technically correct decision. Running the 16 kW model in a space that is too small forces the compressor to constantly turn on and off (short-cycle), which reduces seasonal efficiency (COP) and shortens the compressor's operational lifespan.
Electrical Load Optimization: The 14 kW model draws less starting and running current per phase than the 16 kW flagship. If your local grid has strict power limitations, the 14 kW version provides a safer electrical margin while still delivering massive heating capacity.
Efficiency at Partial Loads: For homes in the 120–150 m² range, the HPGM-14BP operates closer to its optimal partial-load efficiency during mild winter days, ensuring a higher overall seasonal performance coefficient than an under-loaded 16 kW unit.

Best Suited For:

Owners of medium-to-large residences (120–150 m²) with three-phase power who want a highly efficient, space-saving heating and cooling system.
Properties with extensive underfloor heating networks where a balanced, stable grid load is essential.

Might Not Be Suited For:

If your home's heated area exceeds 150–160 m² or has high heat losses, the HPGM-16BP (380V) is required to handle the load without relying on backup electrical heaters.
If your property is under 100 m², both models are oversized; you should look at the single-phase HPGM-10BP or HPGM-8BP instead.
