- Radiator systems
- Fan coil units
- Domestic hot water tanks
- Underfloor heating
4. Outstanding Energy Efficiency – ErP A+++ / A++
- ErP A+++ at 35°C outlet water temperature
- ErP A++ at 55°C outlet water temperature
- Custom energy-consumption settings for different customer needs
- Built-in SG (Smart Grid) function reduces electricity bill
This ensures excellent seasonal heating performance and lower operating costs for homeowners.
5. Ultra-Low Noise Performance
With optimized airflow design and noise-reduction engineering, ensuring a quiet and comfortable home environment.
1) The CAREL system can be selected for different application scenarios on requirements to reduce noise and ensure a comfortable environment, such as day mode and night mode.
2) Self-developed all-round noise reduction, double-layer noise reduction of the compressor.

6. Wide Operating Range – From –25°C to 45°C
Engineered for extreme climates, the system works stably in ambient temperatures from –25°C to 45°C. This guarantees reliable heating in freezing winters and efficient cooling during hot summers.
7. Built-in Remote App Control & IoT Cloud Platform
All models come with standard App control and IoT cloud connectivity, enabling users to:
- Monitor system performance anytime
- Adjust modes and temperatures remotely
- Receive intelligent alerts and energy-use insights
This enhances convenience and improves long-term system efficiency.40

8. Certified for Quality & Incentives (CE, CB, ErP Report, Keymark, MCS)
The product meets multiple international certification standards:
- CE, CB – product safety and compliance
- ErP Report – high energy-efficiency documentation
- Keymark – supports heat pump subsidy applications in several European countries
- MCS – required for claiming heat pump subsidies in the United Kingdom
These certifications ensure both product reliability and eligibility for local government incentive programs.
9. CAREL Intelligent Control System
