Samsung EHS 12 kW Monobloc Air Source Heat Pump R290 - Three Phase

The Samsung EHS Mono R290 12 kW Three-Phase is a monobloc air source heat pump designed to meet medium-high thermal demands in single-family homes and small commercial spaces, providing heating, cooling, and domestic hot water with a single outdoor unit.

It features R290 refrigerant (GWP = 3), which has a very low climate impact and complies with current European F-gas regulations. Its monobloc architecture houses the refrigeration circuit in the outdoor unit, simplifying the indoor hydraulic installation.

High temperature for boiler replacement

Especially suitable for renovation projects with conventional radiators or systems requiring high supply temperatures.

• Heating outlet temperature: 15–75 ºC.
• Domestic hot water: up to 70 ºC with outdoor temperatures as low as -10 ºC without electric backup (depending on conditions).
• Enlarged heat exchanger (up to +39.6% surface area) for improved thermal transfer.
• Reinforced compressor with higher compression ratio for reliable operation at high pressures.

Power and operational stability

• Heating capacity (A7/W35): 12.0 kW.
• Cooling capacity (A35/W18): 12.0 kW.
• Heating operating range: -25~35 ºC.
• Cooling operating range: 10~46 ºC.

Quiet operation

• Sound pressure (normal mode): 47 dB(A).
• 4-step silent mode: down to 35 dB(A).
• Double-layer acoustic insulation and optimized grille design to reduce compressor vibrations and noise.

Design and dimensions

The 12 and 16 kW versions feature a larger chassis to optimize heat exchange and structural stability, while maintaining a discreet dark gray finish.

• Net dimensions (W x H x D): 1270 x 1018 x 530 mm.

Specific safety for R290

• Optimized piping layout to minimize leak risk.
• Pressure sensor for refrigerant detection in the water circuit.
• Forced fan mode and air separator at water outlet in case of incident.
• Potential ignition sources sealed and located at the top of the unit.

Professional installation and maintenance

Quick access to internal components via a removable side panel with three screws, reducing installation and maintenance time. Installation intended for qualified professionals with three-phase power supply.

Connectivity and energy control

• SmartThings Energy: real-time consumption monitoring and activation of energy-saving modes.
• EHS Cloud Service: remote diagnostics with access to error reports, equipment status, and technical data for professionals.

Indicative coverage by thermal load

The climate-controlled area depends on the building’s insulation and conditions. Indicative reference (requires load calculation):

• 30–40 W/m²: approx. 300–400 m² (well insulated)
• 50–60 W/m²: approx. 200–240 m² (average insulation)
• 80–100 W/m²: approx. 120–150 m² (poor insulation)

Note: Indicative values; always confirm with a thermal study of the project.
