Samsung vs Mitsubishi Heat Pumps: Which Is Better?
The best choice between Samsung and Mitsubishi depends on your property, budget and heating priorities. Samsung may appeal to homeowners looking for competitive pricing and smart home features, while Mitsubishi Electric is worth considering if you prioritise a long track record in heating technology and UK-manufactured equipment.
Both brands offer efficient systems, so comparing specific models and their suitability for your home is the best way to make an informed decision.
Why Choose Samsung Heat Pumps
Samsung was founded in 1938 in Daegu, South Korea, by Lee Byung chul as a small trading business selling groceries such as dried fish and noodles. Samsung Electronics followed in 1969, and the group has since become one of the world’s best known technology brands, making everything from smartphones and televisions to washing machines and air conditioning.
Samsung has used its air conditioning expertise to build its EHS (Eco Heating System) range of air to water heat pumps. The range includes the EHS Mono monobloc, the low noise EHS Mono HT Quiet for higher temperatures, newer R290 models and the ClimateHub, an all in one indoor unit that combines the controls with a hot water cylinder. Samsung heat pumps link with the SmartThings app, so you can control your heating alongside other smart devices in your home.
Pros & Cons of Samsung
| Pros | Cons |
| Often the most affordable of the major brands | A shorter heating track record in the UK than Mitsubishi |
| Quiet operation, especially the HT Quiet models | Not built in the UK |
| Excellent smart home integration through SmartThings | Smaller installer network than the longest established brands |
| Higher temperature models suit many older homes | Most standard models still use R32 rather than R290 |
| Space saving ClimateHub all in one indoor unit | Best warranty terms depend on using an approved installer |
Should You Choose Samsung?
Choose Samsung if:
- You want a quality heat pump at a competitive price.
- You already use Samsung SmartThings or like the idea of controlling everything from one app.
- Low noise matters, for example in a terraced street or close to neighbours.
- You want a neat all in one indoor unit to save space.
Do not choose Samsung if:
- You would rather buy a heat pump made in the UK.
- You want the brand with the longest heating track record in British homes.
- You need a specialist model built for very cold, exposed locations.
Why Choose Mitsubishi Heat Pumps
Mitsubishi Electric was founded in Tokyo in 1921, when it was separated from the electrical side of Mitsubishi’s shipbuilding business. It is part of the wider Mitsubishi group but is a separate company from Mitsubishi Motors. Today it is a global leader in electronics, air conditioning and heating, with its UK headquarters in Hatfield, Hertfordshire.
Its Ecodan range is one of the most widely installed heat pump brands in the UK. Ecodan units sold here are designed and built at Mitsubishi Electric’s factory in Livingston, Scotland, which has been making heat pumps for well over a decade. The range includes the standard Ecodan R32 models, newer Ecodan R290 models that can reach around 75°C, and Zubadan models built for very cold weather.
Pros & Cons of Mitsubishi
| Pros | Cons |
| Ecodan units are built in the UK, in Scotland | Usually more expensive than equivalent Samsung models |
| Long track record and large UK installer network | Standard R32 Ecodan models reach lower temperatures than R290 models |
| Strong UK support, training and spare parts | MELCloud app feels less modern to some users |
| Zubadan models built for very cold weather | Fewer smart home links than Samsung SmartThings |
| Newer R290 models reach around 75°C for older homes | Best warranty terms depend on using an approved installer |
Should You Choose Mitsubishi?
Choose Mitsubishi if:
- You like the idea of a heat pump built in the UK, with strong local parts and support.
- You want a brand with a long, proven track record in British homes.
- You live in an older home and want the high temperatures of an Ecodan R290 model.
- Your property is exposed and you want a model designed for the coldest days.
Do not choose Mitsubishi if:
- Keeping the upfront price as low as possible is your main goal.
- You want your heating to link neatly with a wider smart home setup.
- A slick, modern app is a top priority.
Samsung vs Mitsubishi Heat Pumps: Key Differences
Samsung and Mitsubishi offer efficient air source heat pumps, but they differ in pricing, smart features, manufacturing and experience in the heating market. Samsung may appeal to homeowners looking for modern controls and value for money, while Mitsubishi Electric has a longer track record in heating technology and UK manufacturing.
Below, we compare these key areas and assess which brand comes out on top in each category.
Efficiency
Samsung and Mitsubishi heat pumps are both highly efficient. Their main air source models achieve the top A+++ energy rating for low temperature heating and seasonal efficiency (SCOP) figures of up to around 4.5 to 5 in test conditions. In plain terms, you could get four to five units of heat for every unit of electricity you pay for.
In real homes, the difference between them is small. Good system design, correctly sized radiators and sensible controls matter far more than the brand.
Winner: Draw. Both are excellent when installed properly.
Performance in Cold Weather
Both brands keep heating well in cold weather, with standard models working down to around minus 25°C. Mitsubishi also offers its Zubadan range, designed to hold its heat output in very low temperatures. In Kent and the South East, among the mildest parts of the UK, a standard model from either brand will cope comfortably, whether you live inland near Headcorn (TN27) or on the coast at Deal (CT14).
Winner: Mitsubishi, narrowly, thanks to its specialist Zubadan models.
Maximum Water Temperature for Older Homes
Higher water temperatures help older homes with smaller radiators. Samsung’s EHS Mono HT Quiet reaches around 65°C to 70°C, and its newer R290 models reach around 75°C. Mitsubishi’s standard Ecodan R32 reaches around 60°C, and its newer Ecodan R290 range reaches around 75°C.
For period properties in Rochester (ME1), Canterbury (CT2) or Tunbridge Wells (TN1), the higher temperature models from either brand can reduce the need for radiator upgrades.
Winner: Draw. Both brands now offer R290 models that reach around 75°C, and Samsung’s R32 HT Quiet runs a little hotter than Mitsubishi’s standard R32 Ecodan.
Noise Levels
Both brands make quiet heat pumps, but Samsung has put particular focus on low noise with its HT Quiet range, which is designed for homes where the outdoor unit sits close to neighbours. Mitsubishi Ecodan units are also quiet in normal use, and newer R290 models from both brands have been designed with low noise in mind. In England, a heat pump must meet a limit of 42 decibels at your neighbour’s nearest window to count as permitted development.
Winner: Samsung, narrowly, for its dedicated quiet models.
Refrigerant and Environmental Impact
Most standard models from both brands use R32, which has a global warming potential of 675, much lower than older refrigerants. Both brands now also offer R290 models, a natural refrigerant with a global warming potential of just 3, which is seen as the most future proof option as European rules tighten.
Winner: Draw. Pick an R290 model from either brand if environmental impact is a priority.
Reliability and Track Record
Mitsubishi Electric has been making Ecodan heat pumps for UK homes for well over a decade, so there is a long record of real world performance, and installers are very familiar with its products. Samsung is a newer name in UK home heating, but it brings huge manufacturing experience and its heat pumps have built a solid reputation. Either way, reliability depends mostly on correct installation and yearly servicing.
Winner: Mitsubishi, for its longer UK heating track record.
Where the Heat Pumps Are Made
Mitsubishi Ecodan units sold in the UK are built in Livingston, Scotland. Samsung heat pumps are made in its own factories outside the UK. For homeowners who like to buy British made equipment, this is a clear plus for Mitsubishi.
Winner: Mitsubishi.
Installation and Running Costs
Samsung heat pumps are often among the most affordable from the major brands. As a rough guide for a typical three bedroom home, a Samsung system might cost around £7,500 to £13,000 before the grant, compared with around £8,500 to £14,500 for Mitsubishi. After the £7,500 Boiler Upgrade Scheme grant, some Samsung installations can cost very little.
| Cost | Samsung | Mitsubishi |
| Typical installed cost before grant | £7,500 to £13,000 | £8,500 to £14,500 |
| Boiler Upgrade Scheme grant | £7,500 | £7,500 |
| Typical cost after grant | £0 to £5,500 | £1,000 to £7,000 |
| VAT on installation | 0% (until at least March 2027) | 0% (until at least March 2027) |
| Approx. yearly running cost, standard tariff | Around £740 | Around £740 |
| Approx. yearly running cost, heat pump tariff | Around £430 | Around £430 |
| Annual service | Around £100 to £200 | Around £100 to £200 |
Installed costs are rough guides for a typical three bedroom home. The running costs are illustrative only. They assume:
- about 10,000 kWh of heat a year
- a SCOP of around 3.5
- electricity at around 26p per kWh, or around 15p per kWh on a heat pump tariff
Insulation, system design and your electricity tariff will make the biggest difference to your bills.
Running costs are very similar because both brands are equally efficient. Insulation, system design and your electricity tariff will make the biggest difference to your bills.
Winner: Samsung, for a lower upfront cost in many cases.
Warranty and Aftercare
Both brands offer a standard manufacturer warranty, with longer cover available when the system is fitted and registered by an approved installer. The exact length depends on the model, the installer and whether you keep up annual servicing. Mitsubishi’s long UK presence means a large network of trained engineers, which helps with aftercare.
Winner: Draw. Always ask your installer to confirm the warranty in writing for your exact model.
Smart Controls and Apps
Samsung’s heat pumps work with SmartThings, the same app used for Samsung TVs, appliances and many other smart devices. That makes it easy to control your heating alongside the rest of your home and set up automations. Mitsubishi uses the MELCloud app, which is reliable and well established, and popular with installers for remote monitoring, but feels more basic to some users.
Winner: Samsung.
Product Range and Flexibility
Both brands offer monobloc and split systems, higher temperature models and all in one indoor units, Samsung’s ClimateHub and Mitsubishi’s Ecodan all in one cylinders. Mitsubishi adds the cold climate Zubadan range, while Samsung offers dedicated quiet models.
Winner: Draw.
Customer Ratings and Reviews
Both brands are widely reviewed by UK homeowners, and ratings on Which? and Trustpilot change over time. Remember that brand reviews often cover many product types, from phones to fridges, so look for reviews of the heat pumps themselves, and check your installer’s reviews too.
Winner: Draw. Check the latest scores for both brands before you decide.
Design and Appearance
Samsung’s EHS Mono units have a clean, modern white finish, while Mitsubishi Ecodan units have a light grey case that blends in well against most walls. Both are smart and unobtrusive.
Winner: Draw. This one comes down to personal taste.

Frequently Asked Questions
How Long Do Samsung and Mitsubishi Heat Pumps Last?
Samsung and Mitsubishi heat pumps typically last around 15 to 20 years when installed properly and serviced once a year. That compares well with a gas boiler, which usually lasts 10 to 15 years. Keeping the outdoor unit clear of leaves, snow and garden clutter helps it last longer.
What Size Samsung or Mitsubishi Heat Pump Do I Need?
The size of Samsung or Mitsubishi heat pump you need depends on your home’s heat loss, which is worked out with a room by room calculation. Both brands offer models from around 4 to 5 kW for small, well insulated homes up to 14 kW or more for larger properties. Most three bedroom homes need between 5 and 10 kW.
Do Samsung and Mitsubishi Heat Pumps Work With Underfloor Heating?
Samsung and Mitsubishi heat pumps both work very well with underfloor heating. Because underfloor heating warms a room through a large surface area, it runs at low water temperatures, which is where heat pumps are most efficient. Many homes combine underfloor heating downstairs with radiators upstairs.
Do Samsung and Mitsubishi Heat Pumps Work With Solar Panels?
Samsung and Mitsubishi heat pumps both work well with solar panels. Free electricity from your roof can run the heat pump during the day, especially for heating hot water, which lowers your bills. Adding a home battery lets you store spare solar power and use it in the evening.
Can a Samsung or Mitsubishi Heat Pump Cool My Home?
A standard Samsung or Mitsubishi air to water heat pump is designed for heating and hot water rather than air conditioning. If you want cooling, both brands also make air to air heat pumps that can heat and cool individual rooms, and these can be fitted alongside your main heating system.
