  • A+++ Energy Efficiency
    The R290 monoblock heat pump achieves the highest A+++ energy efficiency rating under EU ErP standards. At 35°C water outlet temperature, the unit delivers exceptional seasonal efficiency, translating to substantial savings on energy bills for end users.
  • Full DC Inverter Technology
    Unlike fixed-speed compressors that constantly cycle on and off, the full DC inverter compressor adjusts its speed continuously to match real-time heating or cooling demand. This eliminates energy-wasting start-stop cycles, maintains precise temperature control, and extends compressor lifespan — with stable operation down to -25°C.
  • Outlet Water Temperature Up to 75°C
    Compatible with underfloor heating systems, fan coil units, and traditional radiators. The maximum outlet water temperature of 75°C makes this heat pump ideal for existing building retrofits where higher water temperatures are required. Paired with a hot water tank, it ensures a steady supply of domestic hot water.
  • WiFi Smart Control with IOT & OTA
    Built-in WiFi module enables remote monitoring and control via mobile APP from anywhere. Smart IOT connectivity allows seamless integration with smart home systems. OTA (Over-the-Air) support ensures the system stays up-to-date with the latest firmware improvements without on-site visits.
  • Dual Temperature Zone
    The dual temperature zone function allows independent temperature settings for different heating systems — floor heating at 35°C and radiators at 55°C. Each zone operates at the optimal temperature for its specific application, maximizing comfort and energy savings.
  • Low Noise Operation
    Advanced noise reduction technology ensures exceptionally quiet operation, making it suitable for residential areas and noise-sensitive environments. The full DC inverter drive contributes to reduced vibration and lower operating noise.
  • Certified for Quality and Government Subsidies
    The Micoe R290 monoblock heat pump is CE, SG Ready, ErP and RoHS certified, ensuring reliable performance, energy efficiency and full compliance with European market standards.In many European countries, government subsidies and rebates are available for high-efficiency heat pump systems. With SG Ready certification and A+++ energy efficiency, this R290 heat pump meets the requirements for these incentive programs — helping end users reduce installation costs while delivering long-term energy savings.
  • Warranty & After-Sales Service
    Micoe provides comprehensive after-sales service for the R290 monoblock heat pump, including warranty coverage, technical support, and Global Service Network. 
  • Advanced Manufacturing & Quality Assurance
    Micoe operates five manufacturing bases spanning over 800,000 m² with 38 production lines and an annual capacity exceeding 1.7 million units. With 95% core components made in-house, every heat pump undergoes helium leak testing (7X stricter than national standards) and 100% factory inspection covering 9 categories with 50+ performance indicators. Micoe also operates the industry's first zero-carbon research building( zero-carbon heat pump laboratory building ) — a $28 million facility with 48 laboratories, testing from -60°C to +55°C. Products are exported to over 100 countries worldwide.

  • Residential Homes

Single-family homes, villas, and apartments — providing year-round heating, cooling, and domestic hot water in one integrated system. Ideal for homeowners seeking to reduce energy bills while maintaining consistent indoor comfort.

  • Multi-Family Buildings

Apartment complexes and condominiums — centralized heating and hot water supply with independent temperature control. The dual temperature zone function allows different heating systems to operate at optimal temperatures (floor heating at 35°C, radiators at 55°C), accommodating diverse resident needs.

  • Light Commercial Applications

Small offices, retail stores, cafes, and restaurants — reliable heating, cooling and hot water for spaces with moderate demand. The 8-18kW capacity range and 75°C outlet water temperature provide sufficient output without the complexity and cost of larger commercial systems.

  • Renovation & Retrofit Projects

Replacing gas or oil boilers in existing buildings — the high 75°C outlet temperature ensures compatibility with older radiator systems. This is a key application in Europe's decarbonization drive, allowing building owners to transition to clean heating without replacing existing heat distribution infrastructure.

  • New Build Residential Developments

Ready integration with underfloor heating systems and smart home controls. A+++ energy efficiency helps developers meet tightening energy performance regulations and achieve green building certifications such as Passivhaus or LEED.
