To reduce carbon emissions and curb global warming, this R290 Full DC Inverter Heat Pump has been developed. Compared to R410A (GWP 2100) and R32 (GWP 675), R290 has a GWP of less than 20, recognized as the most eco-friendly refrigerant in the industry.
Meets year-round needs for house heating, cooling, and domestic hot water (via 3-way valve). Modes include: Domestic Hot Water Only, Cooling Only, Heating Only, Heating + DHW, and Cooling + DHW.
Operates stably and efficiently in extremely cold regions down to -25ºC without EVI technology, maintaining a high COP and outputting 75ºC hot water for comprehensive home climate control.
Intelligently adjusts operating frequency to maintain constant room temperatures. Saves up to 50% energy compared to ON-OFF units and up to 75% compared to traditional boilers. Includes DC Inverter Compressor, Fan Motor, and Water Pump.
5-Inches large touch screen and "Smart Life" Wi-Fi App support multiple languages. User-friendly design facilitates easy local operation and remote management.
Includes Powerful, Smart, Silent, and Vacation modes. Users can optimize energy consumption based on actual needs to significantly reduce electricity bills.
Passed ERP A+++ energy class tests. Reaches A+++ at both 35°C and 55°C water temperatures with a SCOP as high as 4.86, ensuring ultra-high energy efficiency.
Utilizes special three-layer sound insulation cotton and advanced noise reduction technology to ensure smooth operation without mechanical noise.
Remote monitoring via Wi-Fi or DUT. Automatically records operating parameters and syncs error reports to service providers for rapid solutions and reduced maintenance costs.
