Retro Pumps
1 / 5
To reduce carbon emissions and curb global warming, the 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): Domestic Hot Water Only, Cooling Only, Heating Only, Heating+ DHW, Cooling+ DHW.
Operates stably and efficiently in extremely cold regions without EVI technology, maintaining high COP and outputting 75ºC hot water for complete home comfort.
Intelligently adjusts operating frequency to maintain constant temperatures. Saves up to 50% energy compared to ON-OFF units and 75% compared to traditional electric boilers. Features Panasonic DC Inverter Compressor and stepless fan motors.
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.
Supports remote monitoring via Wi-Fi or DUT. Error reports are synchronized for quick solutions, saving after-sales costs and time for users and dealers.
