Samsung EHS Gen 7 Review: Best Value Heat Pump in the UK?

The Samsung EHS Gen 7 has quickly earned a reputation among UK installers as the best value air source heat pump on the market. If you are reading this samsung heat pump review wondering whether a relatively new entrant can genuinely compete with established names like Vaillant and Mitsubishi, the short answer is yes. Samsung’s combination of R290 refrigerant, class-leading noise levels, a 7-year warranty, and a price point significantly below the competition makes the Gen 7 a compelling choice for UK homeowners.

Is the Samsung EHS Gen 7 the Best Value Heat Pump?

Yes, the Samsung EHS Gen 7 offers arguably the best value in the UK heat pump market for 2026. Priced at £7,500–£11,000 installed before the £7,500 BUS grant, it delivers a seasonal COP of 3.5–4.0 and operates efficiently down to -25°C. This makes it one of the cheapest heat pumps to both buy and run, with out-of-pocket costs as low as £1,000–£3,500 after the grant for a standard installation.

Samsung’s key advantages are its competitive pricing, quiet operation (37–42 dB depending on model) and the ClimateHub integrated cylinder option that simplifies installation. The Gen 7 uses R32 refrigerant and comes with a five-year warranty extendable to seven. The trade-off is a smaller UK installer network compared to Mitsubishi or Vaillant, though Samsung has expanded its certified partner programme significantly in recent years. For budget-conscious homeowners seeking proven performance, it is hard to beat.

Samsung EHS Gen 7 Specifications and Key Features

The EHS Gen 7 is a monobloc air source heat pump available in capacities from 5kW to 16kW. It uses R290 (propane) refrigerant with a global warming potential of just 3, putting it alongside the Vaillant Arotherm Plus as one of only two mainstream R290 heat pumps available in the UK market.

The standout headline figure is a COP of up to 5.10 at A7/W35, which is among the highest laboratory ratings of any heat pump sold in Britain. The unit is also remarkably quiet, with a noise level of just 35dB in quiet mode at 1 metre, making it the quietest mainstream heat pump available.

Real-World COP and Seasonal Performance

While the laboratory COP of 5.10 is impressive, real-world performance in UK homes paints a more nuanced picture. Early monitoring data from UK installations shows seasonal COP figures between 3.2 and 4.5, with the best results coming from well-insulated homes running low flow temperatures with underfloor heating.

The Gen 7’s R290 refrigerant gives it a genuine thermodynamic advantage in mild UK conditions. R290 has better heat transfer properties than R32, particularly at moderate outdoor temperatures of 2-10C where UK heat pumps spend most of their operating hours. This translates to real efficiency gains of approximately 5-10% compared to equivalent R32 units in typical UK weather.

In colder conditions below 0C, the Gen 7 maintains good performance down to -15C, though COP drops to approximately 2.3-2.8 at these extremes. The unit continues operating down to -25C, though at reduced capacity. For the vast majority of UK winters, this cold-weather performance is more than adequate.

Noise Performance: The Gen 7’s Biggest Advantage

At 35dB in quiet mode at 1 metre, the Samsung EHS Gen 7 is the quietest mainstream heat pump in the UK market. To put this in context, 35dB is quieter than a whispered conversation. At the 3-metre measurement distance used for planning regulations, the quiet mode figure drops to approximately 23-25dB, which is well below the 42dB permitted development limit.

This makes the Gen 7 an outstanding choice for terraced houses, semi-detached homes, and any property where the outdoor unit must be positioned close to a neighbour’s boundary. Many installations that would struggle to meet planning noise limits with other brands can comfortably use the Samsung without any acoustic mitigation.

Even in standard operating mode, noise levels of 42-52dB at 1 metre are competitive. The unit achieves its quiet operation through a variable-speed compressor, optimised fan blade geometry, and extensive vibration dampening in the chassis.

Samsung Heat Pump Installed Costs and Value

This is where the samsung heat pump review gets particularly interesting for cost-conscious buyers. The EHS Gen 7 is significantly cheaper than the Vaillant Arotherm Plus and Daikin Altherma 3, with fully installed costs typically ranging from £8,000 to £11,000 for a standard UK home.

After the £7,500 BUS grant, the net cost drops to as little as £500-£3,500. At the lower end, this makes a Samsung heat pump system cheaper than a new gas boiler installation, which is a remarkable position for a premium renewable heating system.

The lower cost is not due to inferior quality. Samsung achieves the price advantage through manufacturing scale (the company produces millions of heat pumps globally for their air conditioning division), simpler packaging with fewer accessories included as standard, and lower brand premium in the UK heating market compared to established names.

SmartThings Integration and Controls

The Gen 7 integrates with Samsung’s SmartThings app, providing remote control of heating schedules, hot water timing, and basic energy monitoring. For homeowners already in the Samsung smart home ecosystem, this is a convenient addition.

The app allows scheduling, zone control (if the system supports it), and monitoring of current operating parameters. It is not as feature-rich as the Daikin Onecta platform for detailed energy analytics, but it covers the essential functions well and has improved significantly since the Gen 7 launched.

The Samsung also includes a weather compensation function that automatically adjusts flow temperature based on outdoor conditions. When properly configured by the installer, this is one of the most effective ways to optimise efficiency and can improve SCOP by 10-20% compared to fixed flow temperature operation.

Warranty, Reliability and Installer Network

Samsung offers a 7-year parts and labour warranty as standard on the EHS Gen 7, which is the longest standard warranty of any mainstream heat pump brand in the UK. Vaillant offers 5 years standard (7 with approved installers), Mitsubishi offers 5 years, and Daikin offers 5 years.

The 7-year warranty reflects Samsung’s confidence in the product, but it does require annual servicing by a Samsung-certified engineer to remain valid. Servicing costs are comparable to other brands at approximately £100-£180 per year.

The main concern with Samsung in the UK market is the smaller installer network compared to Mitsubishi and Vaillant. Samsung has been rapidly expanding its accredited installer base, but in some rural areas, finding a Samsung-certified installer may involve a longer wait or higher travel costs. This is improving year on year as the brand gains market share.

Who Should Choose the Samsung EHS Gen 7?

The Samsung EHS Gen 7 is the strongest choice for homeowners who want the best combination of value, efficiency, and quiet operation. It is particularly well-suited to:

• Budget-conscious buyers who want the lowest net cost after the BUS grant
• Terraced and semi-detached homes where the 35dB quiet mode solves neighbour noise concerns
• Well-insulated properties where the 65C maximum flow temperature is sufficient
• Homeowners who already use Samsung SmartThings for home automation
• Environmentally motivated buyers who want R290 refrigerant at a lower cost than Vaillant

The Gen 7 is less suitable for older, poorly insulated homes that need flow temperatures above 65C. In these cases, the Vaillant Arotherm Plus (75C) or Daikin Altherma 3 HT (70C) are better choices. It is also worth noting that the 65C limit applies to the maximum output, not the ideal operating point. For optimal efficiency, aim to run the Samsung at 35-45C flow temperature.

If your home needs insulation improvements to bring heat demand down, tackling that before or alongside the heat pump installation will allow you to use lower flow temperatures and extract the best performance from the Gen 7. Combining the heat pump with solar panels and a smart electricity tariff can reduce heating costs to as little as £300-£500 per year.
