Samsung EHS Quint: Heating, Hot Water and Air Conditioning From One Heat Pump
The Samsung EHS Quint combines air-to-water heating, domestic hot water and air-to-air heating and cooling within a single outdoor heat-pump system. It’s an interesting development for homeowners who want central heating and proper room-by-room air conditioning without installing two separate outdoor units.
Most conventional air-to-water heat pumps provide central heating and hot water. If you also want air conditioning, you’ll often need a separate system.
I have a heat pump and separate air conditioning at home myself. After approximately 18 years working in heating-system design, a product that brings those functions together naturally interests me.
However, an interesting product isn’t automatically the right choice for every property.
This guide explains what Samsung has confirmed about the EHS Quint, what still needs establishing for UK installations and which engineering decisions matter before committing to the system.

What Is the Samsung EHS Quint?
The Samsung EHS Quint is a combined air-to-water and air-to-air heat-pump system.
Its central feature is the ability to supply several different heating and cooling requirements from one outdoor unit.
Depending on the approved configuration, these include:
- Wet central heating: Radiators, underfloor heating and compatible hydronic heating arrangements.
- Domestic hot water: Heating a suitable hot-water cylinder.
- Air conditioning: Compatible direct-expansion indoor units providing room heating and cooling.
- Heat recovery: Redirecting heat extracted during cooling towards domestic-hot-water production.
Samsung describes operating modes that allow different areas of the building to receive heating and cooling simultaneously.
That is an important distinction from a conventional reversible air-to-water heat pump.
Rather than relying on chilled water circulated through radiators or underfloor heating, the Quint can use dedicated air-conditioning indoor units to provide effective room cooling.
For a more detailed explanation of the equipment and operating principles, read What Is the Samsung EHS Quint?
Heating, Cooling, Hot Water and Heat Recovery
The Quint’s main attraction is that it brings functions normally associated with separate heating and air-conditioning systems into one integrated arrangement.
Wet Central Heating
The air-to-water side supplies heated water to a suitable central heating system.
This can include radiators or underfloor heating, provided they have been designed or assessed to deliver the required room temperatures.
As with any heat pump, the building’s heat loss, emitter outputs and proposed heating-water temperatures are important.
The available heating capacity must also be checked against the manufacturer’s performance data at the required operating conditions.
Domestic Hot Water
The Quint can provide domestic hot water through a compatible hydronic arrangement and suitable cylinder.
Cylinder capacity, heat-exchanger performance, recovery times, storage temperatures and household demand still require assessment.
Samsung’s published domestic-hot-water outdoor operating range should not be confused with the temperature the system can maintain inside the hot-water cylinder.
Domestic hot-water design remains an important part of the overall system specification.
Air Conditioning
Compatible air-to-air indoor units provide direct room heating and cooling through refrigerant pipework.
These might include appropriately selected wall-mounted or other manufacturer-approved indoor arrangements.
Unlike attempting to cool a home through conventional radiators, dedicated air-conditioning units can provide meaningful room cooling, including temperature and humidity control.
However, every room requiring cooling needs its own assessment.
A bedroom with substantial solar gains may have a very different cooling requirement from a north-facing living room.
Heat Recovery
One of the Quint’s most interesting features is its ability to recover heat during cooling.
Ordinarily, an air-conditioning system removes heat from indoor rooms and rejects it outside.
Samsung describes the Quint as being capable of redirecting some of that extracted heat towards domestic-hot-water production.
This could reduce the energy required to heat water when there is simultaneous cooling and hot-water demand.
However, the value of that feature depends on how much cooling is required, when it operates, available hot-water storage capacity and the system’s controls.
Heat recovery is a useful engineering opportunity, not a guarantee of free hot water or a fixed percentage saving.
CONSIDERING HEATING AND COOLING TOGETHER?
Before committing to one system or two, find out what your home actually needs.
Samsung EHS Quint Models and Published Specifications
Samsung’s GB product information identifies three outdoor model references.
| Outdoor model | Advertised capacity | Electrical supply |
|---|---|---|
| AE125HCTPESEU | 12.5 kW | Single-phase |
| AE160HCTPESEU | 16.0 kW | Single-phase |
| AE125HCTPGSEU | 12.5 kW | Three-phase |
Samsung lists R32 refrigerant and a maximum published heating leaving-water temperature of 65°C under specified outdoor conditions.
Its documentation also describes simultaneous air-to-air and air-to-water operating modes, together with heat recovery for domestic hot water.
What Do These Specifications Mean for a Real Installation?
Headline specifications don’t provide enough information to select a heat pump for an individual home.
For example, Samsung’s 65°C leaving-water claim applies within a stated outdoor temperature range of −5°C to +35°C. It shouldn’t be interpreted as a guarantee of maximum output at 65°C in every weather condition.
Similarly, Samsung’s claims about maintaining heating capacity at low outdoor temperatures are model-dependent.
The designer must check the exact model’s available output at the selected outdoor design temperature and required heating flow temperature.
Published sound figures also need interpreting correctly. Sound pressure and sound power are different measurements, and an installation still needs a site-specific acoustic assessment.
The manufacturer’s data is a starting point for engineering selection, not a substitute for it.
Is the Samsung EHS Quint Suitable for a Typical UK Home?
This is one of the most important questions for anyone considering the Quint.
Samsung’s published outdoor models are in the 12.5 kW and 16 kW advertised capacity classes.
Many UK homes have design heat losses considerably below those figures, which raises an obvious question:
Could the Samsung Quint be too large for a smaller property?
The answer cannot be established from its advertised capacity alone.
A designer needs to examine both maximum and minimum heating outputs at the relevant operating conditions.
Maximum Heating Output
The heat pump must provide sufficient heating capacity to meet the property’s calculated design heat loss.
The selected water temperature and outdoor design conditions affect this assessment.
Minimum Modulation
During milder weather, a property may require only a fraction of its peak heating capacity.
The heat pump needs to manage that reduced demand effectively.
If its minimum available output is substantially greater than the building’s heating requirement, the system may cycle more frequently, depending on water volume, hydraulics and controls.
We shouldn’t assume the Quint is unsuitable for smaller homes without verified modulation data. Equally, we shouldn’t assume it is suitable simply because Samsung describes it as residential equipment.
Heating and Cooling Loads Are Different
A home requiring 6 kW of winter heating doesn’t automatically require 6 kW of summer cooling.
Cooling loads are influenced by glazing, solar exposure, occupancy, internal gains and room orientation.
Each proposed air-conditioning indoor unit must be selected against the relevant room cooling requirement.
Domestic hot-water requirements and simultaneous operating modes must also be considered.
The correct question isn’t whether the Quint can heat and cool a home. It’s whether the exact configuration is appropriate for that particular building.
Our Samsung EHS Quint Design Survey guide explains what needs checking.
Why One Outdoor Unit Could Be an Advantage
A combined heating and cooling system has several potential advantages.
For a property undergoing major renovation, reducing the number of outdoor units may help with available space, building appearance and equipment placement.
It could also offer more integrated control between heating, cooling and hot-water production.
The heat-recovery capability provides another potential benefit where cooling and domestic-hot-water demand overlap.
However, one outdoor unit doesn’t automatically mean a simpler or cheaper installation.
The system still requires a suitable wet-heating arrangement, hot-water equipment and refrigerant pipework serving compatible air-conditioning indoor units.
Controls, electrical requirements, condensate drainage, acoustic assessment and maintenance all remain important.
The refrigerant work also requires appropriately F-gas-certified personnel.
There is a reliability consideration too: a shared outdoor unit creates a degree of dependence between services. With separate heating and cooling systems, a failure in one outdoor unit may leave the other available.
The advantages need weighing against the complete installation, not just the number of outdoor units.
Who Should Consider the Samsung EHS Quint — and Who Might Not Need It?
The Quint may be particularly interesting for homeowners planning heating and cooling together from the beginning.
Potential applications include:
- New builds where heating and cooling are being designed together.
- Major renovations with accessible pipework routes.
- Boiler replacements where proper air conditioning is also wanted.
- Properties with limited suitable outdoor-unit locations.
- Projects where coordinated heating, cooling and hot water could offer a practical advantage.
However, separate systems may be more appropriate in some circumstances.
If a home already has a modern, correctly functioning heat pump, replacing it solely to gain air conditioning may be difficult to justify.
Likewise, someone wanting cooling in only one or two bedrooms may find that a small dedicated air-conditioning system alongside conventional wet heating is more practical.
Homes requiring immediate boiler replacement may also benefit from considering equipment with established availability, installer support and grant arrangements.
A conventional air-to-water heat pump combined with separate air conditioning remains an important alternative.
Samsung isn’t the only manufacturer developing combined solutions. The Daikin X Series offers another approach, with its own specifications and operating limitations.

What Must Be Confirmed Before Specifying a Quint?
Before a Samsung EHS Quint becomes the basis of a final installation design or quotation, several questions need answering.
| Requirement | What must be established |
|---|---|
| Outdoor model | Exact reference and available heating/cooling capacity |
| Modulation | Minimum and maximum output at relevant conditions |
| Indoor units | Manufacturer-approved combinations and limits |
| Wet heating | Compatible hydronic equipment and operating temperatures |
| Refrigerant design | Approved pipe lengths, connections and installation requirements |
| MCS | Exact product and installer certification |
| Grant | Eligibility of the complete proposed installation |
| Acoustic performance | Suitable location and site-specific noise assessment |
| UK support | Availability, warranty, training and service arrangements |
| Installation price | Fully scoped and evidenced quotation |
A manufacturer product page is not sufficient evidence that all these requirements have been satisfied.
The exact proposed configuration matters, particularly for a system combining different heating and cooling technologies.
MCS Certification and the Boiler Upgrade Scheme
MCS product certification and Boiler Upgrade Scheme eligibility are related but separate matters.
A product’s certification should be verified using its exact reference. An eligible installation also needs to satisfy all relevant BUS requirements.
Ofgem’s Product Eligibility List can help identify potentially eligible products, but Ofgem explicitly states that inclusion doesn’t guarantee the complete installation qualifies.
The Quint combines air-to-water and air-to-air functionality. The grant treatment of that particular combined configuration needs authoritative confirmation rather than assumptions based on the equipment’s general description.
A combined air-to-water and air-to-air system should not automatically be treated as a fossil-fuel hybrid, but neither should grant eligibility be assumed.

Until the exact grant arrangement has been confirmed for a proposed installation, any quotation should make the financial assumptions explicit.
Should You Wait for the Samsung EHS Quint or Design Your System Now?
You don’t need to decide on the Samsung Quint before investigating your home’s heating and cooling requirements.
In fact, I would normally establish those requirements before choosing any particular heat pump.
A proper assessment can identify:
- Whole-house and room-by-room heat loss.
- The suitability of existing radiators.
- Appropriate heating flow temperatures.
- Room-by-room cooling loads.
- Domestic-hot-water requirements.
- Practical equipment locations and installation constraints.
Those findings remain useful whether you eventually choose the Quint, another combined system or separate heating and cooling equipment.
For a homeowner planning a renovation, the design can also help identify pipework routes and space requirements before floors and walls are finished.
This allows the building work to progress intelligently without committing prematurely to a particular manufacturer.
Design the heating and cooling requirements first. Select the equipment once its suitability and availability are established.

Frequently Asked Questions About the Samsung EHS Quint
Can the Samsung EHS Quint provide heating, cooling and hot water?
Yes. Samsung describes the EHS Quint as a combined air-to-water and air-to-air system capable of providing wet central heating, domestic hot water and compatible direct-expansion heating and cooling. Its published operating modes include simultaneous functions and heat recovery.
Is the Samsung EHS Quint available in the UK?
Samsung has official GB product pages and has demonstrated the Quint publicly in the UK. However, we haven’t independently confirmed general UK purchasing availability or a complete supported installation route. Check our availability tracker for the latest documented evidence.
Is the Samsung EHS Quint MCS certified?
We cannot currently confirm an exact product-directory listing for the published outdoor models. The last detailed HLH model checks were recorded in August 2026, and a current directory check remains necessary. Product certification should be verified using the exact model reference rather than assumed from the Samsung brand.
Is the Samsung EHS Quint eligible for the Boiler Upgrade Scheme?
Eligibility for the proposed combined system hasn’t been independently established. The relevant product certification, installation configuration, grant classification and installer requirements all need confirming before including a grant deduction in a quotation.
How much does the Samsung EHS Quint cost?
We don’t have a verified UK installed price for a defined Quint configuration. The total will depend on the selected equipment, number of indoor air-conditioning units, hot-water arrangements, radiator upgrades, pipework, electrical installation and other property-specific work.
Could the Quint be too large for my home?
Potentially, but this cannot be established from the 12.5 kW or 16 kW advertised capacity classes alone. The actual heating output, minimum modulation, building heat loss and system operation must all be assessed before deciding whether a model is suitable.
Can I keep my existing radiators?
Possibly. The existing radiators need checking against the calculated room-by-room heat losses at the proposed flow and return temperatures. Some may be suitable, while others may need replacing or upgrading. This is a heating-design decision rather than a feature unique to the Quint.
Independent Heating and Cooling Design for Your Home
The Samsung EHS Quint is an interesting development, but the starting point for a successful installation should still be the property rather than the equipment.
At Heat Loss Hub, we provide independent heating-system design services for homeowners planning heat pumps, renovations and combined heating-and-cooling projects.
We can establish your home’s heating requirements, assess existing emitters and investigate the design options for heating, domestic hot water and cooling.
This work can be useful before you commit to Samsung or any other manufacturer.
Where specialist air-conditioning design or refrigerant-system information is required, the appropriate technical scope and responsibilities need to be agreed.
Our independent assessment doesn’t guarantee that the Quint will ultimately be suitable, available or grant eligible.
Instead, it helps you make an informed decision using reliable building information and appropriate engineering.
