In this review, we delve into the Samsung EHS Mono Outdoor air source heat pump’s specs, features, pros and cons, and costs.
While Samsung was founded in 1938 as a grocery trading store, it has now evolved into global a leader in home appliances including air source heat pumps.
Samsung’s heat pumps use innovative technology to increase comfort and reduce energy bills for both homes and commercial premises. The company also regularly provides comprehensive training programmes for pump installers and offers customers who use them extended guarantee options.
This heat pump is compact (940mm x 1420mm x 330 mm) and quite lightweight (108kg), allowing for different mounting options. Only a small control box 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 per cent of space compared to other air source heat pumps and heating systems.
One of the main advantages of this air source heat pump is that the system has the ability to incorporate different fuel sources, all of which are considered in the installation design. For example, the Samsung EHS Mono Outdoor can be installed with third-party domestic hot water tanks or combined with a pre-plumbed Samsung ClimateHub tank.
There are several models available ranging from 5kW to 16kW, meaning the heat pump is suited for both residential and commercial environments. All the models come with ready-to-use WiFi kits, antifreeze liquid and low-loss headers. All Samsung heat pumps are also Microgeneration Certification Scheme (MCS) accredited.
This air source heat pump is compatible with the Samsung SmartThings app, from which you can control the temperature inside your home as well as switch between the heat pump’s different modes.
The Samsung EHS Mono Outdoor 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.
The range of Samsung EHS Mono Outdoor air source heat pumps cost around £4,000 for the unit only. With installation and additional equipment, the heat pump’s cost can climb to around £6,000 to £12,000 depending on your location and the complexity of the project. 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).
As of September 2025, Samsung UK is rated 3.2 stars out of 5 on Trustpilot, but out of the 13,000 reviews there aren’t many specifically around heat pumps. Overall, opinions of the company are polarised, with many people praising the ease of ordering online and the flexibility of payment options while others mention issues getting in touch with customer service and unreliable products.
The Samsung EHS Mono Outdoor air source heat pump is a great option for homes that need a powerful and efficient heating source that also doesn’t take up too much space.
It’s suitable to be combined with a range of other heating and energy sources, and thanks to the SmartThings app, you can control it remotely and make it part of your smart home ecosystem.
