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

HPGM-12BP (380 V)

Name: HPGM-12BP (380 V)
SKU: HPGM-12BP (380 V)

Cooling: 11,0 kW

Heating: 12,0 kW

The HPGM-12BP (380V) is a high-performance air-to-water monobloc heat pump with a nominal capacity of 12.0 kW, engineered to run on a stable three-phase 380V electrical supply. We recommend this model for medium-to-large private homes, spacious townhouses, and cottages ranging from 100 to 120 m² (up to 130 m² in highly insulated modern builds). If your property has access to three-phase power and requires a highly reliable, space-saving heating, cooling, and domestic hot water (DHW) solution, this 12 kW setup offers the perfect balance. By choosing a monobloc, you save valuable indoor living space, as all key hydraulic components are housed entirely in the outdoor chassis.

Year-Round Comfort

This three-phase system is designed for stable, year-round operation, certified for heating at 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 technology monitors and adjusts water temperatures with an accuracy of 0.5°C, ensuring excellent microclimatic stability and preventing draft sensations.

Technical Advantages & Features

Top-Tier Seasonal Efficiency (A+++ Class): The system extracts up to 75% of its required thermal energy directly from the ambient air, significantly lowering your seasonal utility bills compared to traditional gas or electric boilers.
Balanced Three-Phase (380V) Operation: Utilizing three phases distributes the electrical load evenly across your electrical panel. This prevents phase overload and voltage drops, which is especially important during peak winter heating demands when auxiliary heaters might activate.
All-in-One Outdoor Concept: The outdoor unit integrates a high-efficiency plate heat exchanger, a DC water pump, an expansion vessel, a flow switch, and safety valves, delivering a pre-assembled, ready-to-use water heating loop.
Premium DC Inverter Compressor: Powered by a highly reliable inverter compressor with advanced acoustic blankets to keep outdoor noise and vibration to an absolute minimum.
Eco-Friendly R32 Refrigerant: Fully optimized for low-GWP R32 refrigerant, which improves thermodynamic heat transfer efficiency by 10% and operates with a smaller refrigerant charge volume.
Wired Touchscreen Controller: Includes an intuitive wired controller to program complex weather-dependent heating curves, vacation modes, weekly schedules, and DHW priority cycles.

Installation & Operation Insights

From our engineering teams' experience: For the 12 kW three-phase model, we highly recommend installing a buffer tank of 60 to 80 liters to ensure smooth defrost cycles and prevent compressor short-cycling.
Since the monobloc contains water and sits entirely outdoors, safeguarding against freezing during power outages is critical. We strongly advise filling the heating 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 rapid: because the refrigerant loop is hermetically sealed at the factory, there is zero need for copper line brazing or flaring on site. The installer only connects insulated water lines from the outdoor unit to the building's manifold.

Comparison: HPGM-12BP (380V) vs. HPGM-14BP (380V)

While both models share the same heavy-duty three-phase configuration, choosing between the HPGM-12BP (380V) and the larger HPGM-14BP (380V) depends on your property's precise thermal demands.

Feature / Metric	HPGM-12BP (380V)	HPGM-14BP (380V)
Nominal Thermal Capacity	12.0 kW	14.0 kW
Recommended Heating Area	100 – 120 m²	120 – 150 m²
Electrical Load	Lower current draw per phase	Slightly higher current draw per phase
Sub-Zero Output Reserve	Highly efficient for mid-sized homes	Larger absolute reserve for larger loads
DHW Recovery Time	Rapid recovery	Even faster recovery for high-use homes

Key Takeaways from the Comparison:

Preventing Compressor Short-Cycling: If your home's heated area is around 100–120 m², the HPGM-12BP (380V) is the technically correct choice. Installing the larger 14 kW model in a smaller space forces the compressor to cycle on and off too frequently (short-cycling), which increases energy consumption and accelerates compressor wear.
Optimized Power Limits: The 12 kW model has a lower peak current draw per phase compared to the 14 kW version. If your home's total allocated power limit from the utility company is restricted, the 12 kW unit provides a safer operating margin.
High Efficiency at Partial Loads: For homes in the 100–120 m² range, the HPGM-12BP operates closer to its sweet spot of partial-load efficiency during mild winter days, ensuring a higher overall seasonal performance coefficient (COP).

Best Suited For:

Owners of medium-to-large residences (100–120 m²) with three-phase power who want a highly efficient, space-saving heating and cooling system.
Properties with limited indoor space where allocating room for an indoor hydro-module is not practical.

Might Not Be Suited For:

If your home's heated area exceeds 130–140 m² or has high heat losses, the HPGM-14BP (380V) is recommended to handle the load without relying heavily on backup electrical heaters.
If your property is under 80 m², the 12.0 kW capacity is oversized; you should look at the single-phase HPGM-8BP or HPGM-6BP instead.
