The Samsung EHS Mono R32 16kW Three-Phase Air Source Heat Pump is the largest capacity unit in Samsung's Gen 6 monobloc range, built for large UK homes and small commercial buildings with substantial heat loss. At this output, a three-phase electrical supply is the standard specification, spreading the load across three lines rather than placing it all on a single circuit.
The 16kW unit delivers a COP of 4.42 at standard A7/W35 conditions and continues to operate down to -25°C outdoor air temperature, with leaving water temperatures of up to 65°C for compatibility with underfloor heating and radiator systems. As with the rest of the range, the complete refrigeration circuit is factory-sealed in the outdoor unit, removing the need for F-Gas handling on site.

Lead Time - Please Check Before Ordering
This three-phase unit typically carries a lead time of up to 15 business days. Please contact us to confirm current stock and lead time before placing an order, particularly where installation is scheduled against a fixed date.
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.
Highest Capacity in the Mono Range
At 16kW heating output, this is the largest domestic-scale unit in Samsung's Gen 6 monobloc line-up, suited to larger properties or higher-demand applications.
Cold-Climate Performance at Scale
Rated to operate continuously down to -25°C outdoor air temperature, maintaining full heating output through the coldest UK winters even at this higher capacity.
Three-Phase Electrical Design
Runs on a three-phase 380-415V supply as standard at this output, distributing the higher electrical draw across three lines for a more manageable per-phase current.
Low-GWP R32 Refrigerant
Uses R32 refrigerant (GWP 675), requiring a smaller charge than older R410A systems for a reduced environmental footprint.
Quiet BLDC Twin Rotary Compressor
The BLDC Twin Rotary compressor keeps sound pressure to 54 dBA despite delivering the highest capacity in the range.

Confirm Exact Circuit Rating With Your Installer
Per-phase MCA/MFA figures for this three-phase model should be confirmed against Samsung's current installation manual for the exact site voltage, as they are not published on the standard specification sheet used for this listing. Your installer will size the circuit protection based on the nameplate rating of the unit supplied.
What size property needs a 16kW heat pump?
The 16kW model is typically specified for large detached homes or small commercial buildings with substantial heat loss. An accurate heat loss calculation should always confirm the correct capacity for a specific property rather than sizing on floor area alone.
What is the typical lead time on this product?
This three-phase unit typically has a lead time of up to 15 business days. Please contact us to confirm current stock and lead time before ordering, especially for time-sensitive installations.
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.
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.
