Our heat pump is built with advanced technology to deliver higher efficiency, faster heating, and long-lasting reliability. With a high-performance micro-channel heat exchanger, optimized components, a thermally efficient tank, and intelligent defrost control, it ensures consistent hot water while using less energy — even in challenging conditions.
A. High Efficiency Micro Channel Heat Exchanger
Improves heat transfer efficiency by up to 30%
Compact, lightweight design for easier installation
Corrosion-resistant — tested 1500 hours salt spray
Quick temperature response for stable hot-water supply
B. High Efficiency System Composition
EXV provides precise refrigerant control
Dedicated DHW compressor designed for R290 systems
DC fan motor delivers quiet, efficient airflow
Bigger evaporator boosts heating performance and reliability
C. Thermal Efficient Tank
Thick polyurethane insulation reduces heat loss
Lower running costs due to better heat retention
Eco-friendly — insulation is F-gas free
D. Intelligent Defrost
Hot-gas bypass ensures faster defrost
Saves energy while keeping performance stable
Intelligent control completes cycles quickly and prevents heat loss
