An air source heat pump manufacturer Europe buyers can evaluate should provide more than a product catalogue. European distributors, installers and project teams need model-specific performance data, conformity documents, hydraulic and electrical information, commissioning guidance, spare parts and a clear route to after-sales support.
EXINDA manufactures air-to-water heat pump systems for European residential, retrofit, multi-family and selected commercial applications. The European product focus includes R290 monoblock heat pumps that deliver energy to hydronic systems for space heating, cooling and domestic hot water.
EXINDA’s manufacturing base is in China, while its products are supplied to Europe through distributors, regional partners and project cooperation. This distinction matters: “for Europe” describes the target market, product application and documentation requirements; it does not claim that the factory is located in Europe.
What Is an Air Source Heat Pump?
An air source heat pump uses outdoor air as an energy source. Its refrigeration circuit absorbs low-temperature heat from the air, raises the refrigerant temperature through compression and transfers the energy into the building.
The term covers two main building-heating categories:
| Category | Heat delivery method | Typical application |
|---|---|---|
| Air-to-air heat pump | Delivers heated or cooled air directly indoors | Individual rooms and ducted air systems |
| Air-to-water heat pump | Delivers heated or cooled water to a hydronic system | Radiators, underfloor heating, fan coils and hot-water cylinders |
EXINDA’s European residential heat-pump proposition focuses primarily on air-to-water systems. This makes the range relevant to European buildings that already use water-based heating, as well as new projects designed around underfloor heating or fan coils.
Pool heat pumps also use outdoor air, but their water temperatures, controls, heat exchangers and application requirements differ from building-heating products. A pool heat pump should not be selected as a substitute for a residential hydronic heat pump.
Why Do European Buyers Search for an Air Source Heat Pump Manufacturer?
Different buyers use the same search phrase for different reasons.
- Distributors want a product range, territory strategy, documentation, training and spare-parts plan.
- Installers need selection data, hydraulic requirements, manuals, commissioning support and fault diagnosis.
- Heating contractors need products for boiler replacement, radiator retrofit and new-build systems.
- Consultants need performance tables, sound data, operating envelopes and technical submittals.
- Developers need repeatable system design, project documentation and support for multiple units.
- Building owners need a dependable local supply and service route.
A useful manufacturer page must therefore explain not only what the equipment is, but also how the manufacturer supports the complete route from model selection to long-term operation.

The exact capacity, refrigerant, voltage, operating envelope and certification scope must be confirmed from the current model-specific submittal.
Why Does EXINDA Focus on Air-to-Water Systems for Europe?
Hydronic heating is common in many European buildings. Existing homes may already contain radiators, pipework and hot-water cylinders, while new buildings often use underfloor heating or fan coils.
An air-to-water heat pump can connect outdoor-air energy with these water-based emitters. This creates several possible project routes:
- Replace a fossil-fuel boiler while retaining suitable hydronic distribution
- Upgrade selected radiators and lower the system water temperature
- Supply low-temperature underfloor heating in a new home
- Combine heating and cooling through fan coils
- Produce domestic hot water through a compatible cylinder
- Stage multiple units for a larger residential or commercial load
The heat pump remains only one part of the system. Real performance also depends on building heat loss, emitter design, water temperature, hydraulic balancing, controls, commissioning and user settings.
Which Refrigerant Is Used in EXINDA’s European Residential Range?
EXINDA’s current European residential monoblock range uses R290, also known as propane. R290 is a natural refrigerant with low global-warming impact compared with many traditional fluorinated refrigerants.
R290 does not by itself guarantee a suitable product. Buyers should still evaluate:
- Capacity at the required outdoor and water temperatures
- Seasonal performance
- Minimum and maximum output
- Sound data
- Operating envelope
- Defrost strategy
- Controls and communications
- Safety instructions
- Certification scope
- Manufacturer and distributor support
R290 is flammable. Product placement, clearances, handling and service must follow the exact installation manual and applicable local requirements. In a monoblock design, the refrigeration circuit is factory assembled within the outdoor unit, while the installer connects the hydronic water circuit.
For a detailed category explanation, read the EXINDA R290 air-to-water heat pump guide.
How Should Buyers Compare Air Source Heat Pump Manufacturers?
The lowest equipment price does not establish the lowest project or lifetime cost. Buyers should evaluate the complete manufacturer and support structure.
| Evaluation area | Questions to ask the manufacturer |
| Product range | Are suitable capacities available for the target market? |
| Rated performance | Is capacity shown at the project’s actual outdoor and water conditions? |
| Modulation | What are the minimum and maximum outputs? |
| Documentation | Are current submittals, manuals and wiring diagrams available? |
| Certification | Does the exact model fall within the claimed certificate scope? |
| Controls | Are weather compensation, DHW control and communications supported? |
| Installation | Are hydraulic, electrical and safety requirements clearly documented? |
| Commissioning | Is product-side setup guidance available? |
| Spare parts | Can a regional service stock be planned? |
| Warranty process | What evidence and diagnostic data are required? |
| Distribution | Is there a clear sales and local-service route? |
| Training | Can distributors and installers receive product training? |
Manufacturers should be able to explain limitations as clearly as capabilities. Unsupported statements such as “suitable for every climate” or “works with every radiator system” are not a substitute for model-specific engineering data.
Why Nominal Capacity Is Not Enough
A product labelled 12 kW does not necessarily produce 12 kW under every operating condition. Output and efficiency change with outdoor-air temperature, leaving-water temperature and compressor operating point.
Before selecting a model, request:
- Building heat loss at the local winter design temperature
- Heating capacity at or near that outdoor condition
- Required leaving- and return-water temperatures
- COP at a stated test point
- SCOP under the relevant declared climate and application
- Minimum output during mild weather
- Water-flow and pressure-drop requirements
- Maximum current and electrical configuration
- Backup-heater information
- Sound power or sound pressure with the test condition
A7/W35 data describe operation at 7°C outdoor air and 35°C leaving water. They should not automatically be used to predict capacity or efficiency at −7°C outdoor air and 55°C leaving water.
Can an Air Source Heat Pump Replace a Gas or Oil Boiler?
Yes, when the building and hydronic system are suitable. Boiler replacement is not simply an equipment swap based on the boiler nameplate.
The project team should assess:
- Building heat loss at design conditions
- Heat-pump output at the required water temperature
- Radiator or underfloor-heating output
- Existing pipe sizes and water flow
- Hydraulic balancing and zoning
- Domestic-hot-water requirements
- Available electrical supply
- Freeze protection and drainage
- Supplementary-heat strategy
The EXINDA UK boiler-to-R290 heat pump retrofit demonstrates integration with an existing radiator loop, domestic-hot-water system and project controls.
The EXINDA heat pump installation in Ireland provides another residential electrification example involving the replacement of traditional gas or oil heating.
Can an Air Source Heat Pump Work With Existing Radiators?
Yes, but radiator output must be checked at the proposed heat-pump flow and return temperatures. Radiators originally selected for a high-temperature boiler may deliver less heat when operated at lower water temperatures.
Possible project improvements include:
- Increasing selected radiator sizes
- Using low-temperature or fan-assisted radiators
- Improving insulation and airtightness
- Rebalancing the hydronic circuit
- Applying weather-compensated control
- Reducing unnecessary water-temperature setpoints
An EXINDA residential installation in Germany retained a radiator-based hydronic system while replacing fossil-fuel heating with an R290 air-to-water heat pump. View the German luxury-villa installation.
Are Air Source Heat Pumps Suitable for Underfloor Heating?
Yes. Underfloor heating can often deliver the required room output with lower water temperatures because it uses a large emitter area. This can create favourable operating conditions for an air-to-water heat pump.
The designer must still check:
- Building heat loss
- Floor output limits
- Pipe spacing and loop length
- Manifold balancing
- Minimum flow
- Floor-finish temperature limitations
- Zoning and actuator behaviour
- Controls for mixed radiator and floor-heating circuits
Can One System Provide Heating, Cooling and Hot Water?
Applicable reversible air-to-water models can support space heating, chilled-water cooling and domestic-hot-water production. The connected system determines how these functions are delivered.
- Radiators and underfloor loops provide space heating.
- Fan coils can provide heating and cooling.
- A compatible indirect cylinder stores domestic hot water.
- Controls establish mode, temperature and hot-water priority.
Cooling requires appropriate emitters and condensation management. Conventional radiators do not normally provide practical space cooling.
An Italian residential complex uses EXINDA R290 air-to-water units for centralized domestic-hot-water production. Read the Italian domestic-hot-water case study.
Can Air Source Heat Pumps Serve Multi-Family Buildings?
Yes. Multi-family systems may be centralized, decentralized or hybrid. Project teams must consider peak and simultaneous loads, zoning, hydraulic distribution, metering, redundancy, domestic hot water and maintenance access.
An EXINDA project in Italy combines centralized and individual R290 heat-pump systems for heating, cooling and domestic hot water. View the EXINDA multi-residential project in Italy.
Multiple applicable units can also be staged in cascade for larger loads. The design should review sequencing, part-load performance, minimum flow, buffer volume, fault resilience and backup strategy.
What European Documentation Should a Manufacturer Provide?
Required documentation varies by country, project type and product. Buyers should match every document to the exact model and electrical configuration.
CE Documentation
Applicable products placed on the European market require the relevant conformity assessment and CE documentation. Buyers should request the declaration and verify the listed model.
ErP Information
ErP documentation may include energy labels, product fiches and seasonal-performance information. The document must correspond to the selected model and configuration.
Heat Pump KEYMARK
Heat Pump KEYMARK is a voluntary third-party certification scheme. Certification is model-specific; a certificate for one product or capacity does not automatically cover an entire range.
MCS for the United Kingdom
UK projects may require an MCS-listed product depending on the project route and programme requirements. Current listing status must be confirmed for the exact model. Read the EXINDA MCS-certified R290 heat pump guide.
Performance and Sound Data
Useful technical evidence can include data tested or declared under applicable EN methods, operating envelopes, capacity tables and sound information. Buyers should confirm whether a value is sound power or sound pressure and review the stated distance and operating mode.
For additional acoustic context, see the EXINDA air source heat pump noise-test article.
