2. Refrigerant & Environmental Design
Both EXINDA and Viessmann R290 heat pump systems use R290 (propane) natural refrigerant.
Key shared environmental characteristics include:
- Very low Global Warming Potential (GWP ≈ 3)
- Zero ozone depletion potential (ODP = 0)
- High thermodynamic efficiency in vapor compression cycles
- Alignment with EU F-Gas Regulation phase-down strategy
R290 is increasingly recognized as a core refrigerant technology for next-generation European heat pump systems.
3. Compliance and Certification Framework(EU Standards)
| Category | EXINDA R290 Heat Pump | Viessmann R290 Heat Pump |

| Ecodesign Framework | Designed to align with EU energy efficiency requirements | Fully aligned with EU Ecodesign directives |
| Engineering Positioning | Standardized performance comparability across test conditions | Strong alignment with German HVAC regulatory engineering standards |
Both systems operate within identical certification frameworks, ensuring consistent regulatory baselines for performance evaluation.
4. Performance and Engineering Behavior
| Category | EXINDA R290 Heat Pump | Viessmann R290 Heat Pump |
|---|---|---|
| Compressor Technology | Full DC inverter compressor system | Advanced inverter-driven compressor system |
| Climate Adaptability | Designed for wide ambient temperature operation | Optimized for stable seasonal performance (SCOP focus) |
| System Philosophy | Engineering-flexible system design | Highly integrated system architecture |
| Application Focus | Multi-load, multi-unit, project-based systems | Residential-focused stable operation systems |
| Installation Design | Monoblock system, no refrigerant piping on site | Integrated system with pre-defined hydraulic logic |
| Engineering Evaluation Focus | Installation flexibility + system adaptability | Lifecycle stability + seasonal efficiency consistency |
From an engineering perspective, EXINDA systems are often evaluated based on installation flexibility and system adaptability in complex project environments.
Viessmann systems are typically evaluated based on system completeness and lifecycle stability within residential applications.
5. System Integration and Installation Approach
| Category | EXINDA R290 Heat Pump | Viessmann R290 Heat Pump |
|---|---|---|
| Hydraulic Configuration | Flexible hydraulic system design | Pre-configured hydraulic system architecture |
| Third-party Compatibility | High compatibility with external HVAC components | Limited external integration, system-ecosystem oriented |
| System Design Approach | Customized engineering system design | Standardized system installation framework |
| Expansion Capability | Supports cascade and modular expansion | Limited to defined system expansion pathways |
| Installation Complexity | Higher engineering flexibility, contractor-driven design | Lower installation complexity, standardized workflow |
| On-site Variability | High design flexibility on-site | Reduced variability due to system standardization |
The key difference lies in project flexibility versus system standardization approach.
6. Engineering Selection Criteria
When selecting a 15kW R290 monoblock heat pump system in Europe, including EXINDA and Viessmann, engineering decisions are typically based on:
- Building heat load calculation (EN 12831 methodology)
- Required supply temperature (low-temperature vs mixed systems)
- Seasonal efficiency performance (SCOP under climate conditions)
- Hydronic system design complexity and water volume
- Installation strategy (custom engineering vs standardized system)
- Climate zone and design temperature conditions across EU regions
System performance in real applications depends heavily on hydraulic design and seasonal load behavior rather than nominal capacity alone.
7. Market Positioning Context
In the European R290 heat pump market, EXINDA and Viessmann operate within the same regulatory and technical framework but serve different market needs:
- EXINDA represents an engineering-oriented HVAC manufacturer focused on system flexibility, project customization, and multi-application deployment.
- Viessmann represents a system-integrated European HVAC manufacturer focused on standardized residential heating solutions and ecosystem-based installation.
Both approaches reflect different strategies within the same decarbonized heating transition landscape in Europe.
8.General Heat Pump System Questions
What is a R290 air-to-water heat pump?
A heat pump using R290 (propane) refrigerant to provide heating, cooling, and hot water through a hydronic system.
Why is R290 used in heat pumps?
Because it has very low GWP (~3), high efficiency, and meets EU F-Gas phase-down rules.
What is SCOP in heat pumps?
SCOP is seasonal efficiency, showing real yearly energy performance under EN 14825 testing.
