The system can also be monitored and controlled with the Samsung SmartThings app for more efficiency and savings.

Pros and cons


  • Works with different fuel sources: The Samsung EHS Monobloc allows various fuel sources, including renewables. All inputs were carefully considered when designing the heat pump, which makes them all easy to install and maintain.
  • Extremely quiet operation: The Samsung EHS Monobloc is one of the quietest air source heat pumps on the market (50db(A) at 1m) and a tranquil choice for a heating system overall. 
  • Easy to install: The Samsung EHS Monobloc air source heat pump comes with a comprehensive installation manual and readily available online literature.


  • Requires a MIM Control Kit: The MIM Control Kit is sold separately (for an additional fee) and is needed to run the system for heat only or with a non-Samsung water tank. This allows the user to operate the heating schedules of their Samsung EHS Monobloc air source heat pump. 
  • Guarantee: The standard Samsung EHS Monobloc heat pump guarantee is only two years. However, you can extend this period to seven years if you use a Samsung approved installer (Samsung has a well regarded programme to train heat pump installers, so this is probably a good idea anyway).
  • Always reverts to  “Money Saver” mode: The Samsung EHS Monobloc is very environmentally conscious. The system automatically reverts to a money saver mode when switched off, meaning you might need to change the setting every time you power it up. You would, however, always start by saving energy.

The Samsung EHS Monobloc is available in a variety of heating outputs and sizes. These units are suitable for both residential properties and commercial environments and can provide hot water and space heating throughout the entire year. This pump offers excellent performance in all seasons and is optimised with an eco-friendly design for outstanding heating efficiency. 

Samsung offers the heat pump in a range of sizes that can fit the specific needs of your home or office, including 5kW, 8kw, 12kW and 16kW options. All the models support both feet and wall-mounted installations and come with ready-to-use wifi kits, antifreeze liquid and low-loss headers. All Samsung heat pumps are also Microgeneration Certification Scheme (MCS) accredited.

How the Samsung EHS Monobloc air source heat pump compares to others

The heat pump is very compact when compared to its competitors (940mm x 1420mm x 330 mm) and quite lightweight, too (108kgs), allowing for different mounting options. There is just a small control box that is required to sit indoors, but that’s all the space the system requires inside your home. Because the heating system is so small and light, the outdoor unit (the only unit required) can save up to 40% space when compared to other air source heat pumps and heating systems. This makes the Samsung EHS Monobloc a particularly interesting choice for commercial properties looking to improve their business efficiency without occupying too much space.

One of the main advantages of this air source heat pump is that the system has the ability to incorporate different fuel sources – and these are all also considered in the installation design. For example, the Samsung EHS Monobloc can be installed with third-party domestic hot water tanks or combined with a pre-plumbed Samsung ClimateHub tank. 

The Samsung EHS Monobloc heat pump is extremely quiet when operating. In fact, it would be hard to find another air source heat pump that produces less sound – just (50db(A) at 1m. This is one of the reasons why many residential properties choose the Samsung EHS Monobloc as their heating system; the fans are almost noiseless, ensuring comfort for homeowners. The system also includes a market-leading calculation software (built to BSEN12831) and an inverter compressor that can operate according to the temperature outside, which makes it even more efficient and flexible. 

This air source heat pump is compatible with the Samsung SmartThings app, which can additionally monitor your Samsung ClimateHub tank if you have one, as well as any other compatible Samsung devices. Another thing you can control with the app is the quiet operation modes of the Samsung EHS Monobloc; for example, setting SilentMode for a more quiet operation. 

The Samsung EHS Monobloc is easy to install, however it needs a MIM Control Kit (sold separately) unless the heat pump is installed with a Samsung pre-plumbed ClimateHub hot water tank. It is recommended, however, that you acquire one of Samsung’s cylinders because they come pre-plumbed, reducing installation time.

How much does the Samsung EHS Monobloc air source heat pump cost?

The range of Samsung EHS Monobloc air source heat pumps cost around £3,630 (including VAT) for the unit only. With installation and additional equipment, the heat pump’s cost can climb to around £6,000 to £12,000 total. The investment in air source heat pumps is significantly higher when compared to other traditional systems, and installations can tend to also require some additional fees (for example, for the hot water tank).

All Samsung air source heat pumps come with a standard two-year manufacturer guarantee. However, there is also a seven-year guarantee available if you use a Samsung-approved installer . This gives the Samsung EHS Monobloc one of the best guarantee options in the UK.

What the professionals say

“Samsung heat pumps are quite attractive compared to the Mitsubishi ones we looked at and it was the only brand that had built in Wifi so you could see all your indoor units on your phone and from there you can do many things to adjust them. Absolutely would recommend them.”

The system is super quiet, and was really easy to connect and control with the Samsung Smart Things App. The contractor we chose did a great job at explaining what they would be doing, and was competitively priced compared to a couple other contractors. Then installation looks great and the system keeps us super comfortable.”

“My only complaint is that every time the unit is turned on, it goes straight to “money saver” mode, which I do not like, as the fan cycling off and on wakes me at night. I have simply gotten into the habit of turning the thing on with 3 clicks; power on, system cycle to fan only, then cool.”

Final recommendation

Samsung’s air source heat pumps use efficient technology to deliver excellent comfort. They can produce up to 4kW of heat while consuming just 1kW of electricity, which makes them over four times more efficient than standard electric heaters. They are also ideal for properties that use solar power too, as they can offset a lot of the cost of running the heat pump. Your overall consumption will be connected to your desired warmth level.
