Samsung Monobloc Heat Pump Gen 7 R290 Standard

Samsung Monobloc Heat Pump Gen 7 R290 Standard

The Samsung EHS Monobloc Gen 7 R290 (standard CXYDEK/CXYDGK series) is the outdoor-only monobloc variant of Samsung’s seventh-generation R290 natural refrigerant heat pump range. Available in 5 kW, 8 kW, 12 kW and 16 kW (single-phase and three-phase), it uses R290 (propane) refrigerant with a GWP of just 3 — not subject to F-Gas phase-down. The key difference from the Integrated variant (CXYBEK): this standard version does not include the built-in hydraulics, wiring board or WiFi. A separate indoor pump and expansion vessel, MIM controller and WiFi kit are required. The pay-off is a lower unit cost and flexibility for installers who prefer to specify their own hydraulic components. Performance: 75°C maximum flow temperature, SCOP up to 4.84 at 35°C (5 kW), A+++ across all four capacities, 35 dB(A) Quiet Mode. Identical R290 compressor and heat exchanger platform as the Integrated variant.

⚠ F-Gas R290 qualified installer required: R290 (propane) is an A3 flammable refrigerant. Installation requires an F-Gas registered engineer with specific R290 competency, using R290-rated tools, gauges and leak detection. This applies to all R290 heat pumps regardless of brand.
⚠ MIM controller and WiFi kit required (not included): This standard variant requires a separate MIM-E03EN control kit and, for SmartThings connectivity, the MIM-H04EN WiFi Kit 2.0. The Integrated variant (CXYBEK) has these built in. Confirm your full system specification with your installer.
ℹ BUS grant eligible — up to £7,500: MCS-listed across multiple certification numbers (varies by model and cylinder). Eligible for the Boiler Upgrade Scheme in England and Wales.
Standard vs Integrated — Which to Choose

Unit cost Lower Higher
Installation complexity Higher — more components Lower
Indoor plant space Larger requirement Minimal
Installer flexibility Specify own hydraulic components Hydraulics pre-specified

Both deliver the same maximum 75°C flow temperature, A+++ SCOP and R290 refrigerant. The Integrated suits simpler installations; the Standard is preferred where the installer wants control over hydraulic component selection.

Frequently Asked Questions
Should I choose the Standard or the Integrated variant?
Choose the Standard (CXYDEK) if: your installer prefers to specify and source hydraulic components independently, you are integrating with an existing indoor plant room, or the lower unit cost is a priority and the additional labour/components cost is acceptable. Choose the Integrated (CXYBEK) if: you want the simplest possible installation, minimal indoor plant space, built-in WiFi without a separate controller dongle, or you are working to a tight installation timeframe. The heating performance is identical — same R290 compressor and heat exchanger platform.
Does this heat pump reach 75°C reliably in winter?
Yes. The Samsung Gen 7 R290 is rated for 75°C leaving water temperature across outdoor temperatures from −10°C to +35°C. At −10°C, Samsung confirm 100 % of rated heating capacity. The 75°C capability is particularly relevant for DHW boost and legacy radiator systems. However, the most efficient way to run the system is at the lowest flow temperature that meets the design heat load — because SCOP drops significantly at higher temperatures. Target 55°C or lower where emitter sizing allows.
Why is R290’s GWP of 3 significant?
GWP (Global Warming Potential) measures how much a unit mass of gas contributes to global warming relative to CO₂ over 100 years. R290 (propane) has a GWP of 3 — compared to R32 (GWP 675) and R410A (GWP 2,088). The F-Gas Regulation in the EU (and UK equivalent) requires phase-down of higher-GWP refrigerants. R290 is not subject to F-Gas phase-down and will remain in use and serviceable indefinitely under current regulations. This is relevant for the 20-year+ lifespan of a heat pump installation: there is no risk of R290 becoming unavailable or expensive due to regulatory phase-down.
