Retro Pumps
1 / 5
To reduce carbon emissions to the environment and curb global warming, an R290 Full DC Inverter Heat Pump has been developed. Compared to R410A refrigerant with a GWP of 2100 and R32 with a GWP of 675, R290 has a GWP of less than 20 and is recognized by the industry as the most eco-friendly refrigerant with the highest development potential.
The perfect performance of the R290 FULL DC INVERTER Heat Pump meets house heating, cooling, and domestic hot water (DHW) needs throughout the year:
Under low ambient temperatures, normal heat pumps often struggle. This R290 FULL DC INVERTER heat pump operates stably and efficiently in extremely cold regions down to -25ºC without EVI technology, maintaining a high COP and outputting 75ºC hot water.
Features a 5-inch large LCD touch screen and "Smart Life" Wi-Fi App support. This user-friendly design supports local languages and English, facilitating easy management for both homeowners and distributors.
The R290 FULL DC INVERTER Heat Pump has passed TUV ERP A+++ energy class tests. It achieves A+++ rating at both 35°C and 55°C water temperatures. With an SCOP as high as 4.86, it ensures ultra-high energy efficiency.
The unit utilizes special three-layer sound insulation cotton combined with noise reduction technology, ensuring smooth and quiet operation without mechanical noise.
