As energy prices remain volatile and the UK pushes towards net-zero targets, air source heat pumps have become one of the most popular low-carbon heating solutions for British homes. Samsung's latest Generation 7 (Gen 7) heat pumps stand out for their efficiency, quiet operation, and future-proof design, particularly with the shift to eco-friendly R290 refrigerant. These systems are ideal for both new builds and retrofits, offering reliable heating even in colder UK winters..
In this expert guide, we'll explore the three main Gen 7 models—including the high-temperature R32 option and the innovative R290 variants—the integrated ClimateHub solutions with Telford-compatible cylinders, the role of the hydro unit, and essential accessories available in the UK market.
The Three Core Samsung Gen 7 Heat Pump Models
Samsung's Gen 7 lineup focuses on monobloc designs, where the outdoor unit handles both refrigerant and water circuits for simpler installation. Here's a detailed breakdown:
1. EHS Mono HT Quiet (R32 Refrigerant) – Ideal for Renovations and High-Temperature Needs
The Samsung EHS Mono HT Quiet is tailored for UK homes undergoing boiler replacements, especially those with existing radiators. It uses R32 refrigerant and excels at delivering high water temperatures.
- Capacities: 8kW, 12kW, and 14kW.
- Key Performance: Up to 70°C hot water output, full heating capacity down to -25°C outdoor temperatures. SCOP ratings around 3.0 at 65°C flow.
- Efficiency and Noise: A+++ rated, with advanced quiet technologies including a horizontal grille and sound insulation for low-noise operation.
- Best For: Older properties needing high flow temperatures without extensive radiator upgrades. MCS-certified for high-temperature applications.
This model is particularly suited to the British climate, maintaining 100% performance in freezing conditions.

2. EHS Mono R290 (Standard Monobloc) – Future-Proof Low-GWP Option
The EHS Mono R290 series marks Samsung's shift to propane (R290) refrigerant with a ultra-low Global Warming Potential (GWP) of just 3—well below upcoming EU regulations limiting GWP to 150 from 2025.
- Capacities: Starting at 5kW, extending to 8kW, 12kW, and 16kW in the broader range.
- Key Performance: Hot water up to 75°C, operation from -25°C to 43°C for DHW. COP up to 5.10, noise as low as 35 dB(A) with 4-step quiet mode and patented Groove Grid Felt insulation.
- Features: Adapted components for safe R290 use, reliable in cold weather with enlarged heat exchangers.
- Best For: Environmentally conscious homeowners seeking compliance with future F-Gas rules.
3. EHS Mono R290 Pump Integrated – All-in-One Convenience
This variant builds on the standard R290 model by integrating hydraulic components directly into the outdoor unit.
- Capacities: 5kW base, with higher options available.
- Key Additions: Built-in pump, expansion tank, control kit, and Wi-Fi kit—reducing indoor space needs and installation time.
- Performance: Similar to the standard R290: 75°C output, ultra-quiet operation, SmartThings app compatibility.
- Best For: Smaller homes or installations where indoor space is limited.
Both R290 models offer SmartThings integration for energy monitoring and automation.

Understanding the ClimateHub and Telford Cylinder Integration
Samsung's ClimateHub is an all-in-one indoor solution that pairs perfectly with Gen 7 outdoor units, combining a hydro unit with a hot water tank for space-saving efficiency.
- Tank Options: 200L or 260L modular tanks (single or three-phase).
-
Integration: Often uses high-quality cylinders from partners like Telford, known for durability and compatibility in UK systems.
- Benefits: Compact design fits alongside kitchen units, provides heating, cooling, and domestic hot water. Supports solar PV or smart grid integration for maximum savings.
The ClimateHub Mono version eliminates refrigerant piping indoors, simplifying setups.
Explainer: The Hydro Unit and Optional Backup Heater
The hydro unit (or hydronic module) is the indoor "brain" of the system, managing water flow between the outdoor unit and your home's heating circuit (radiators, underfloor, or hot water tank).
- Function: Includes components like pumps, valves, filters, and expansion vessels. In wall-mounted or ClimateHub-integrated forms, it ensures efficient heat distribution.
- ClimateHub Specifics: Features a detachable 7" touchscreen, AI optimisation, and emergency mode for uninterrupted operation.
Optional Backup Heater: For extreme cold spells or peak demand, add electric backup heaters (4-6kW built-in, expandable to 9kW with a separate 4kW unit). This provides hybrid reliability without relying solely on the heat pump.
Accessories and Their Applications
UK retailers like Aizo Quality Heating offer a range of Samsung accessories:
- Backup Heaters: 4kW tank heaters for ClimateHub during low outdoor temperatures.
- Controls and Interfaces: Wired controllers, Modbus kits for integration with BMS or third-party thermostats (e.g., Homely).
- Wi-Fi Kits: For SmartThings app control and remote monitoring.
- Other: Mounting kits, valves, and coastal-protected variants for harsh UK environments.
These enhance system flexibility, especially in zoned heating setups.
Why Choose Samsung Gen 7 in 2026?
With rising interest in air source heat pumps across the UK, Samsung's Gen 7 range combines proven reliability, low running costs, and eco credentials. The R290 models are particularly forward-thinking, while the HT Quiet excels in retrofits.
Whether upgrading from a gas boiler or building new, these systems offer long-term savings and comfort. Consult an MCS-accredited installer to assess your home.
