Samsung EHS Mono R32 5kW Monobloc Heat Pump | AE050RXYDEG/EU | Single Phase

Description

The Samsung EHS Mono R32 5kW Air Source Heat Pump is a compact, single-phase monobloc unit built for small and mid-sized UK homes. The complete refrigeration circuit is sealed inside the outdoor unit, so there is no indoor hydro box to plumb in and no F-Gas handling on site - just a water flow and return connection into the property.

Running on low-GWP R32 refrigerant, this 5kW unit delivers a genuine COP of 4.85 at standard A7/W35 conditions and remains fully operational down to -25°C outdoor air temperature, making it a dependable choice through a UK winter. Leaving water temperatures of up to 65°C mean it can serve both underfloor heating and standard radiator circuits without a secondary heat source.

MCS Installation & Control Kit Required

This is an outdoor unit only. A Samsung control kit (MIM-E03EN or equivalent) or a pre-plumbed cylinder solution such as a Samsung ClimateHub is required to complete a working heating and hot water system. Installation must be carried out by an MCS-certified installer to qualify for BUS grant funding and the extended manufacturer warranty.

Compatible Control Kits & Wi-Fi

This unit is completed with either the MIM-E03EN or MIM-E03FN control kit (sold separately) - both provide full heating, hot water, and mixing valve control, with the MIM-E03FN adding a 7" touchscreen display over the standard wired controller. Add the MIM-H04EN Wi-Fi Controller Kit to either control kit for remote monitoring and control via the Samsung SmartThings app. Alternatively, pair this heat pump with a pre-plumbed Samsung ClimateHub or Telford cylinder, which include the necessary controls built in.

Up to 7-Year Warranty

Samsung backs this unit with a standard warranty extendable to 7 years when installed and registered by a Samsung-trained EHS installer, giving long-term cover on one of the most established heat pump platforms sold in the UK.

True Monobloc Design

The entire refrigerant circuit is factory-sealed in the outdoor unit, removing the need for on-site refrigerant handling, F-Gas certification, or an indoor hydro box.

Reliable Cold-Climate Output

Rated to operate continuously down to -25°C outdoor air temperature, with stable heating performance maintained well below 0°C UK winter conditions.

High COP Efficiency

Delivers a COP of 4.85 at standard A7/W35 test conditions, translating into low running costs relative to the heat delivered.

Low-GWP R32 Refrigerant

Uses R32 refrigerant (GWP 675), requiring a smaller refrigerant charge than older R410A systems for a reduced environmental footprint.

Quiet BLDC Twin Rotary Compressor

The BLDC Twin Rotary compressor keeps sound pressure to just 45 dBA, suiting installation close to bedrooms or neighbouring properties.

SmartThings Compatible

Compatible with the Samsung SmartThings app (via optional Wi-Fi kit) for remote monitoring and control of heating and hot water.

Does this heat pump include an indoor control unit or cylinder?

No. This listing is for the outdoor monobloc unit only. To complete a working system you will need a compatible Samsung control kit or a pre-plumbed cylinder solution such as a ClimateHub, sold separately.

What size property is the 5kW model suitable for?

The 5kW Mono is generally sized for smaller, well-insulated homes such as 1-2 bedroom flats or small terraced properties. An accurate heat loss calculation should always confirm the correct capacity for a specific property.

How cold can it get before this heat pump stops working?

The unit is rated to operate down to -25°C outdoor air temperature in heating mode, making it suitable for the coldest parts of the UK without needing a backup heat source for most applications.

Is MCS certification required for installation?

Yes. Installation should be carried out by an MCS-certified installer to ensure compliance with UK regulations, to qualify for available government funding schemes, and to validate the manufacturer's extended warranty.

Can this heat pump run underfloor heating and radiators together?

Yes. With a maximum leaving water temperature of 65°C, the unit can supply both low-temperature underfloor heating and standard radiator circuits, subject to correct system design and zoning.
