Retro Pumps
1 / 5
To reduce carbon emissions and curb global warming, we have developed the R290 Full DC Inverter Heat Pump. R290 has a GWP of less than 20, recognized as the most eco-friendly refrigerant in the industry.
Meet all-year 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
Our units operate efficiently in extremely cold regions down to -25ºC without EVI technology, maintaining high COP and outputting 75ºC hot water.
Intelligently adjusts operating frequency to keep constant temperatures. Saves up to 50% energy compared to ON-OFF units and up to 75% compared to traditional boilers.
Passed the ERP A+++ energy class test. SCOP as high as 4.86, ensuring perfect performance at both 35°C and 55°C water temperatures.
Connected via Wi-Fi for remote monitoring. Real-time error reports allow for quick technical solutions, saving time and maintenance costs.
