EXINDA combines heat pump engineering, European-market product development and OEM/ODM manufacturing capabilities to provide a scalable R290 heat pump platform for distributors, contractors and HVAC brands.
European-Market Certification & Performance
For a professional heat pump supplier, product performance must be supported by standardized testing and market-specific documentation.
EXINDA's European R290 platform is developed around the certification and technical requirements relevant to European residential heating applications, with CE, KEYMARK, CB and MCS-related compliance options available according to the specific model and destination market.
The current R290 range achieves:
-
Energy Class A+++ at 35°C application temperature
-
Energy Class A++ at 55°C application temperature
-
Heating COP exceeding 5.0 under applicable A7/W35 operating conditions
-
Full inverter modulation across the heating capacity range
This gives installers, consultants and distributors a performance platform suitable for both low-temperature heating systems and higher-temperature hydronic applications.
R290 Natural Refrigerant Technology
EXINDA uses R290 propane as the refrigerant across its European residential air-to-water heat pump range.
R290 combines strong thermodynamic performance with very low refrigerant charge requirements and enables the heat pump platform to achieve high leaving-water temperatures while maintaining efficient inverter operation.
The EXINDA R290 range uses refrigerant charges from approximately 0.55 kg to 1.5 kg, depending on model capacity.
For European HVAC distributors and heating-system professionals, this makes the EXINDA R290 platform particularly relevant to the continuing transition toward lower-GWP heating technologies.
Up to 75°C Leaving-Water Temperature
One of the key advantages of the EXINDA R290 air-to-water heat pump platform is its ability to deliver a maximum heating flow temperature of up to 75°C.
This extends the application range beyond new-build homes using low-temperature underfloor heating.
EXINDA R290 heat pumps can be integrated with:
Underfloor Heating
Efficient low-temperature heating for new-build and highly insulated residential properties.
Fan Coil Systems
Hydronic heating and cooling through a single water-based distribution system.
Radiator Systems
Higher leaving-water temperatures provide greater flexibility when replacing boilers in existing residential buildings.
Domestic Hot Water
The same heat pump platform can provide sanitary hot water together with space heating and cooling.
This combination makes the system suitable for both new construction and residential heating renovation projects in Europe.
Cold-Climate Operation Down to -25°C
European heat pump performance cannot be evaluated only under mild ambient conditions.
EXINDA's R290 monoblock heat pumps are designed for operation across an outdoor ambient range of approximately -25°C to 43°C, allowing the same platform to serve heating applications in colder European climates as well as moderate-climate regions.
The variable-speed compressor adjusts output according to building demand and outdoor conditions, while intelligent defrost control helps maintain heating operation when frost forms on the outdoor heat exchanger.
This makes the platform particularly relevant for distributors and contractors serving Central Europe, Northern Europe and other cold-climate heating markets.
Full DC Inverter Technology
Unlike fixed-speed heat pumps that repeatedly start and stop at full capacity, EXINDA's R290 platform uses inverter-driven operation to continuously adjust output according to actual heating or cooling demand.
For example, under the published A7/W35 test condition, EXINDA's range provides broad modulation:
| Model | Heating Capacity Range |
|---|---|
| 6 kW | 2.07–6.82 kW |
| 9 kW | 2.99–8.86 kW |
| 12 kW | 4.58–11.83 kW |
| 15 kW | 5.64–15.72 kW |
| 20 kW | 7.81–22.32 kW |
This capacity modulation allows the system to better match changing building loads rather than operating only at nominal capacity.
For homeowners, the result is more stable water temperature and comfort.
For installers and system designers, it provides greater flexibility when matching the heat pump to real building load profiles.
Heating + Cooling + Domestic Hot Water
EXINDA R290 heat pumps are designed as complete hydronic comfort systems rather than heating-only appliances.
One outdoor monoblock heat pump can support:
Space Heating + Space Cooling + Domestic Hot Water
depending on the system configuration.
The platform can therefore replace or integrate functions traditionally provided by several different systems, giving residential projects a simplified central hydronic solution.
With appropriate hydraulic design, EXINDA R290 heat pumps can be connected to underfloor heating, fan coils, radiators and domestic hot water storage systems.
Hybrid Heating & System Integration
European renovation projects do not always require complete removal of the existing heating system.
EXINDA R290 air-to-water heat pumps can be integrated into hybrid heating configurations together with other energy sources such as:
-
Existing boilers
-
Solar PV systems
-
Solar thermal systems
-
Other auxiliary heat sources
The platform supports intelligent system control and integration possibilities including Modbus RS485, allowing the heat pump to operate as part of a broader residential energy system.
This is particularly useful for renovation projects where an existing hydronic distribution system can be retained while the primary heat source is upgraded.
Intelligent Heating Control
Efficient heat-pump operation depends not only on compressor technology but also on how the system responds to changing outdoor conditions.
EXINDA systems incorporate weather-dependent control strategies that can adjust target flow-water temperature according to ambient temperature.
When outdoor temperature decreases, the controller can increase the required heating-water temperature. When outdoor conditions become milder, the system can reduce the target temperature.
This helps the heat pump avoid unnecessary high-temperature operation and improves the relationship between comfort, water temperature and system efficiency.
Selected models also support:
Wi-Fi / APP Remote Control
allowing users to monitor and adjust operating conditions remotely.
Cascade Control
multiple heat pumps can be linked together, with the current residential platform supporting configurations of up to six units for applications requiring higher total capacity.
European-Grade Hydronic Components
Reliability in an air-to-water heat pump depends heavily on the quality of the refrigeration and hydraulic circuits.
EXINDA's current R290 residential platform uses established HVAC component suppliers including:
Highly Inverter Compressor
Variable-speed compressor technology for heating and cooling modulation.
Alfa Laval Plate Heat Exchanger
Used as the refrigerant-to-water heat exchanger across the current 6–20 kW range.
Wilo Circulation Pump
Integrated water circulation pump for the hydronic circuit.
DC Fan Motors
Electronically controlled outdoor airflow across the complete range.
By standardizing key components across the product family, EXINDA provides distributors and service partners with a more consistent technical platform across multiple capacity models.
Low-Noise Residential Design
Outdoor-unit noise is an important consideration in European residential heat pump projects, particularly where equipment is installed close to bedrooms, neighbouring properties or dense residential developments.
The current EXINDA R290 platform lists outdoor-unit noise levels of approximately:
52 dB(A) for 6 kW, 9 kW, 12 kW and 15 kW models
58 dB(A) for the 20 kW model
under the published product conditions.
The combination of inverter compressor control, DC fan motors and internal acoustic design helps reduce unnecessary full-load operation during lower heating-demand periods.
