Samsung EHS Model Guide

A complete reference covering Samsung EHS heat pump generations, model numbers, specifications, and refrigerant options. From the Gen 5 R410A units through to the latest Gen 7 R290 range.

Generation Comparison

Samsung has released three major generations of EHS heat pump. Each generation brought significant improvements in refrigerant sustainability, maximum flow temperature, and controls.

Gen 6 (R32)

Released around November 2020, the Gen 6 range moved from R410A to R32 refrigerant — cutting GWP from 2,088 to 675. Maximum flow temperature increased to 65°C, the LCD controller was upgraded, and all models gained MCS accreditation. The Gen 6 remains the most widely installed Samsung EHS generation in the UK.

Gen 7 (R290)

The Gen 7 range, released around 2023, makes the leap to R290 (propane) — a natural refrigerant with a GWP of just 3. This future-proofs the units against EU F-Gas regulations and enables flow temperatures up to 75°C, making them suitable for existing radiator systems without upsizing.

Key Highlights

  • R290 refrigerant — GWP of 3 (vs 675 for R32), fully exempt from EU F-Gas phase-down restrictions.
  • 75°C max flow temp — 10°C higher than Gen 6, reducing the need to upsize radiators in retrofit installations.
  • 7" detachable touchscreen — replaces the basic LCD controller from previous generations, with a much more intuitive interface.
  • AI optimisation — learns usage patterns to optimise energy consumption automatically.
  • Emergency mode — maintains basic heating even when the outdoor unit encounters a fault, using the backup heater.
  • Compact 850mm height — the 5 kW and 8 kW models have a significantly reduced footprint compared to Gen 6.

Available capacities: 5 kW, 8 kW, 12 kW, and 16 kW monobloc models. Capacity codes and model number structure follow the same convention as Gen 6 but with updated generation and refrigerant identifiers.

HT Quiet

The HT Quiet variant is designed for installations where noise is a primary concern — particularly in terraced housing, dense neighbourhoods, or where planning permission restricts noise levels at the property boundary.

Minimum noise level

35 dB(A)

Context

Quieter than a typical library

  • Standard Samsung EHS units typically produce 48–54 dB(A) at source, depending on model and operating conditions.
  • Planning regulations in England typically require no more than 42 dB(A) at 1 metre from a neighbour's window.
  • The HT Quiet's 35 dB(A) rating makes it suitable for constrained sites where standard units would fail MCS noise assessments.

Model Number Decoder

Samsung model numbers follow a structured naming convention. Each segment encodes information about the product family, capacity, configuration, and region.

AE 080 R X Y D EG

SegmentMeaningExample
AEProduct family (Air-to-water EHS)AE
050 / 080 / 120 / 160Capacity code (×100 = BTU/h, or roughly kW×10)080 → 8 kW

Y / E / WSub-type (Y = standard, E = split, W = ClimateHub)Y = Standard mono

Tip: ClimateHub models use NW in the configuration position (e.g. AE200RNWMEG), where M = monobloc and S = split variant.

Refrigerant Comparison: R32 vs R290

The shift from R32 to R290 is a significant change driven by EU F-Gas regulations. The EU is progressively phasing down the supply of high-GWP refrigerants, making R290 the long-term choice for new installations.

EU F-Gas Implications

  • The EU F-Gas Regulation is phasing down HFC supply to 21% of 2015 levels by 2030, increasing costs and potentially limiting availability of R32.
  • R290 (GWP 3) is classified as a natural refrigerant and is exempt from F-Gas quota restrictions, making it a future-proof choice.
  • Existing Gen 6 (R32) installations are not affected retrospectively — the regulations apply to new equipment and refrigerant supply.
  • R290 is classified as A3 (flammable), which may impose stricter siting requirements for the outdoor unit compared to R32 (A2L, mildly flammable).
