About Samsung

Samsung is a global technology company best known for its electronics, including smartphones, TVs and home appliances. Founded in South Korea, the company has grown into one of the world’s largest technology brands.

Alongside its consumer electronics, Samsung also develops heating and climate solutions for homes and businesses. Its air source heat pumps are designed to provide heating and hot water while using electricity to extract renewable heat from the air.

Samsung’s air source heat pump range includes the EHS (Eco Heating System), which uses air-to-water heat pump technology. These systems are designed to work with a home’s existing heating system and can offer an efficient alternative to traditional gas or oil heating.

Samsung Air Source Heat Pumps - Quick Overview

EHS Mono R290 Air Source Heat Pump

Available Sizes: 5kW, 8kW, 12kW, 16kW

• Uses low-GWP R290 natural refrigerant

• 4-step Quiet Mode

• Maintains heating performance in temperatures as low as -25°C

• Quiet Mark Certified

The Samsung EHS Mono HT Quiet air source heat pump is designed to provide efficient heating and hot water while keeping operating noise to a minimum. With noise levels as low as 35 dB(A), it can be a suitable choice for homes where quiet operation is important.

The system can produce water temperatures of up to 70°C, making it suitable for use with existing radiators in many homes. It is also designed to maintain heating performance in outdoor temperatures as low as -25°C, helping it operate reliably during colder weather.

Available in sizes from 8kW to 14kW, the EHS Mono HT Quiet can accommodate a range of heating requirements. Its 4-step Quiet Mode gives people greater control over operating noise, while its Quiet Mark certification provides additional reassurance for those looking for a quieter heat pump.

EHS Mono R32 Air Source Heat Pump

Available Sizes: 5kW, 8kW, 12kW, 16kW

• A+++ energy efficiency

• Uses R32 refrigerant

• Designed to operate in colder temperatures

• SmartThings connectivity

• Provides heating and hot water

The Samsung EHS Mono R32 air source heat pump is designed to provide efficient heating and hot water for UK homes. As a monobloc system, the main components are housed in a single outdoor unit, helping to simplify installation.

With an A+++ energy efficiency rating, the EHS Mono R32 can help reduce energy consumption compared with traditional heating systems. It uses R32 refrigerant, which has a lower global warming potential than older refrigerants.

Available in sizes from 5kW to 16kW, the system can suit a variety of property sizes and heating requirements. It also offers SmartThings connectivity, allowing homeowners to control and monitor their heating through compatible Samsung devices.

EHS Split R32 Air Source Heat Pump

• A+++ energy efficiency

• Uses R32 refrigerant

• Heating and hot water in one system

• SmartThings connectivity

• Designed for reliable operation in colder temperatures

The Samsung EHS Split R32 air source heat pump is designed to provide efficient heating and hot water for homes. Unlike the Mono range, the system uses a split design, with the outdoor unit connected to an indoor hydro unit.

With an A+++ energy efficiency rating, the EHS Split R32 can help reduce energy use while providing consistent heating and hot water. It uses R32 refrigerant, which has a lower global warming potential than older refrigerants.

Available in 4kW, 6kW and 9kW sizes, the EHS Split R32 is suited to smaller and medium-sized homes with different heating requirements. It also offers SmartThings connectivity, giving homeowners the option to monitor and control their heating through compatible devices.

Benefits of Samsung Air Source Heat Pumps

Samsung air source heat pumps offer several benefits for people looking for a more efficient way to heat their homes. Like other air source heat pumps, they use heat from the outside air rather than burning fossil fuels to generate heat.

Samsung’s range also includes features designed to make its systems efficient, practical and easy to use:

• Lower energy consumption: Air source heat pumps can use less energy than traditional heating systems because they transfer heat from the air rather than generating heat through combustion.

• Reduced carbon emissions: Since heat pumps use electricity and renewable heat from the air, they can help reduce your home's carbon emissions, particularly when compared with gas or oil heating.

• Efficient heating and hot water: Samsung heat pumps can provide both heating and hot water from one system. Several models in the range also have high energy efficiency ratings, including A+++ models.

• Suitable for existing radiators: Samsung's EHS Mono R290 can produce water temperatures of up to 75°C, while the EHS Mono HT Quiet can reach up to 70°C. This can make these models suitable for homes with existing radiator systems, subject to a property assessment.

• Works in cold weather: Samsung heat pumps are designed to operate in low outdoor temperatures. The EHS Mono HT Quiet, for example, is designed to maintain heating performance at temperatures as low as -25°C.

• Quiet operation: The EHS Mono HT Quiet is designed specifically to minimise noise, with sound levels as low as 35 dB(A). This can be particularly useful when the outdoor unit is located close to living areas or neighbouring properties.

• Smart home connectivity: Compatible Samsung models can connect with SmartThings, allowing homeowners to monitor and control their heating and energy use through compatible smart devices.

• Lower-GWP refrigerant options: Samsung's EHS Mono R290 uses R290 refrigerant, which has a very low global warming potential compared with many synthetic refrigerants. This provides an option for people looking for a lower-impact heating system.

Drawbacks of Samsung Air Source Heat Pumps

While Samsung air source heat pumps can provide efficient, low-carbon heating, they may not be the right option for every home. Like any heating system, there are some potential drawbacks to consider before choosing a Samsung heat pump.

Here are some of the main points to keep in mind:

• Higher upfront cost: An air source heat pump can cost more to install than a traditional gas boiler. However, government heat pump grants such as the Boiler Upgrade Scheme may help eligible homeowners reduce the initial cost of a heat pump.

• Installation requirements: Heat pumps need enough outdoor space for the unit, as well as suitable indoor space for components such as a hot water cylinder. Your home may also need changes to its heating system before installation.

• Lower efficiency in very cold weather: Although Samsung's EHS systems are designed to operate in low temperatures, heat pumps generally work harder as the outside temperature falls. This can increase electricity use during particularly cold periods.

• May require larger radiators: Heat pumps typically operate at lower flow temperatures than gas boilers. Some homes may therefore need larger radiators or underfloor heating to provide enough warmth.

• Electricity costs: Unlike a gas boiler, a heat pump runs on electricity. While it can be highly efficient, the overall heat pump running cost will depend on your electricity tariff, your home's insulation and how efficiently the system is operated.

• Outdoor unit space: Samsung air source heat pumps require an outdoor unit with sufficient space around it for airflow. This can be a consideration for homes with small gardens, limited outdoor space or restrictions on where equipment can be installed.

• Professional installation required: Correct sizing and installation are important for heat pump performance. A qualified installer, such as Glow Green, will need to assess your property, insulation, heating system and hot water requirements before installation.
