Samsung EHS Gen6 Mono R32 16kW 1-Phase Air-to-Water Outdoor Heat Pump AE160RXYDEG/EU

• F-Gas regulations apply. R32 is a fluorinated greenhouse gas (GWP 675). All installation, commissioning, and decommissioning work must be carried out by an F-Gas certified engineer. Refrigerant site records must be maintained.
• No integral pressure relief valve. The outdoor unit does not include a PRV. A compliant pressure relief valve must be installed in the hydraulic circuit in accordance with BS EN 12828 and Building Regulations Part G.
• MCS registration required for BUS grant. The unit and installation must be registered by an MCS-certified installer before the Boiler Upgrade Scheme grant is submitted.
• Minimum system water volume: 50 litres. The installer must calculate total hydraulic circuit volume and add a buffer vessel if the minimum cannot be met from pipework and cylinder coil volume alone.

• Control module not included. The outdoor unit requires the Samsung MIM-E03CN control module (which includes Touch Controller MWR-WW10N) to operate. Order separately or as part of a ClimateHub package.
• Wi-Fi not embedded. SmartThings App connectivity requires the optional MIM-H04N Wi-Fi Kit (sold separately).
• Dedicated electrical circuit required: 40 A MCB. This unit draws MCA 32.0 A / MFA 40.0 A. Confirm available supply capacity and cable sizing to MCA before specifying. Note: a 3-phase variant (AE160RXYDGG/EU, 380–415 V) is also available for commercial properties or where a 3-phase supply exists.
• Filter/strainer mandatory on the return water pipe to protect the outdoor unit heat exchanger from system debris. Clean regularly to maintain minimum flow rate.

• MCS Listed — qualifies for the UK Boiler Upgrade Scheme (BUS) £7,500 grant when installed by an MCS-certified contractor.
• Compatible with the Samsung ClimateHub tank-integrated hydro unit (200 L or 260 L) or third-party cylinders and control kits from various manufacturers.
• 2-Zone Control supported — optimise a high-temperature radiator zone and a low-temperature underfloor heating zone independently from a single outdoor unit.
• PV-Enabled & Smart Grid Ready — shifts electrical demand to periods of solar surplus or off-peak grid tariffs to minimise running costs.

True Monoblock Architecture

Unlike a split heat pump, the EHS Mono houses the complete refrigerant circuit outdoors. No refrigerant pipework penetrates the building envelope — only insulated water pipes connect the outdoor unit to the indoor hydraulic system. This eliminates F-Gas work on the indoor side, broadens compatibility with third-party cylinders and control kits, and simplifies compliance with Building Regulations Part F.

SCOP 4.48 — ErP A+++ at LWT 35°C

Tested across a full seasonal load profile per EN 14825, this unit achieves SCOP 4.48 at a 35°C leaving water temperature — the ideal operating point for underfloor heating systems. At 55°C flow (for legacy radiator retrofits) the SCOP is 3.53 (A++), still considerably better than a condensing boiler. The inverter-driven compressor modulates continuously to match heat demand, avoiding on/off cycling losses and reducing wear.

−25°C Cold-Climate Performance

The unit maintains full rated output down to −7°C ambient (A−7/W35 peak condition: 14.6 kW) and continues to operate down to −25°C through compressor modulation and supplementary backup heating. Domestic hot water mode remains available down to −25°C, covering the entire range of UK winter conditions with confidence.

Up to 65°C Flow Temperature

A maximum leaving water temperature of 65°C allows this unit to serve legacy radiator systems without mandatory full system re-sizing, provided heat-loss calculations confirm adequate emitter output at the specified flow temperature. For maximum efficiency, the system is best designed to run at 45–55°C or lower, where the SCOP improvement over boiler operation is most significant.

Anti-Salt Heat Exchanger & Robust Casing

The louvred-fin heat exchanger uses G-Fin geometry with an Anti-Salt coating on fins and tubes to resist corrosion in coastal or industrially polluted environments. The powder-coated electro-galvanised steel casing in Samsung's Earth Brown finish provides additional weathering protection. Two axial-flow fans with BLDC motors (2 × 125 W) deliver 118 m³/min airflow at 750 rpm for high throughput with low electrical draw.

Smart Connectivity & Energy Management

Via the optional MIM-H04N Wi-Fi Kit, the unit integrates with the Samsung SmartThings ecosystem for remote on/off, scheduling, and energy monitoring from iOS or Android. The Touch Controller MWR-WW10N (included with MIM-E03CN) supports 2-Zone temperature scheduling, error monitoring, and summer-mode cooling. Smart Grid Ready and PV-Enabled logic allow demand shifting toward off-peak tariffs or surplus solar generation.
