,Full DC Inverter Air Source Heat Pump
The H8 Helios Pro Series is an advanced R290 air source heat pump designed to provide efficient heating, cooling, and domestic hot water from a single compact monobloc system.
Powered by Full DC Inverter technology, the H8 automatically adjusts its operating capacity according to actual heating demand. Combined with natural R290 refrigerant, high-temperature water output, and intelligent control, it provides an efficient and flexible solution for modern residential and commercial heating systems.
With operation down to -25°C and water outlet temperatures up to 75°C, the H8 is engineered for demanding climates and a wide range of heating applications.
The variable-speed compressor and fan continuously adjust the system output according to the required heating or cooling load.
This helps reduce unnecessary energy consumption while maintaining stable water temperatures and comfortable indoor conditions.
The H8 uses R290 refrigerant with GWP=3, supporting the transition toward more environmentally friendly heating technologies.
A two-stage refrigerant leakage protection system provides additional safety during operation.
The H8 can produce outlet water temperatures of up to 75°C, expanding its compatibility with different heating applications.
With a working temperature down to -25°C, the H8 is designed for cold-weather heating applications.
Its AI intelligent defrost system automatically manages defrost cycles to help maintain stable heating performance and minimize unnecessary interruptions.
The H8 achieves ERP A+++ efficiency at both 35°C and 55°C, making it suitable for both low-temperature and higher-temperature heating systems.
Advanced fan and compressor noise reduction technology keeps operating sound as low as 35 dB(A) at 1 meter.
This makes the system suitable for homes, villas, and other environments where low operating noise is important.
The H8 combines local controls with connected smart management functions.
The 7-inch touchscreen controller provides an intuitive interface for daily operation and system configuration.
The temperature curve function helps the system adapt its operation to changing heating requirements and outdoor conditions.
For projects requiring higher heating capacity, up to 8 H8 units can operate in cascade.
This allows the system to be expanded according to project requirements without relying on a single oversized unit.
Suitable for:
- Large residential properties
- Villas
- Apartment buildings
- Small commercial buildings
- Heating renovation projects
- Multi-zone heating systems
The H8 Helios Pro Series supports §14a EnWG-compliant operation, making it suitable for applicable German smart-grid applications.
Its smart control architecture allows the heat pump to work with modern energy management strategies and helps optimize electricity usage.
The H8 combines several functions in one system:
Heating + Cooling + DHW
This makes it a flexible alternative to traditional heating equipment while reducing the need for multiple independent systems.
Its monobloc configuration also simplifies system integration by keeping the refrigeration circuit within the outdoor unit.
