Reliable Monobloc Air to Water Heat Pump for Global Wholesalers
Positioning as a reliable OEM partner, our Monobloc air to water heat pump redefines the standard for domestic hot water solutions. Unlike split systems, this all-in-one unit integrates a high-efficiency compressor and a custom built-in circulation pump, slashing installation time by 40%. Engineered to accommodate both R410A and R134A refrigerants, this system offers unmatched flexibility for wholesalers looking to stock a single unit model that serves diverse regional environmental requirements—from freezing European winters to year-round tropical heat.
Features
Engineered to solve real installation headaches and reduce your after-sales service calls.
Smart Refrigerant Adaptability
Future-proof your inventory. Opt for R410A heat pump water heater variants for superior energy efficiency in ambient temperatures down to -7°C, or switch to the R134A high-temperature heat pump version to deliver outlet water up to 65°C for hotel applications.
Built-in Pump & Hydraulic Module
Eliminate the hassle of sourcing external pumps. Our factory pre-installs and tests the built-in pump heat pump system, ensuring precise flow rates from 1.5m³/h to 3.0m³/h. Critical for retrofit projects.
"One-Stop" OEM Customization
Stand out in a crowded market. We offer true OEM heat pump water heater customization—not just paint, but component tailoring: pump brand (Grundfos/Wilo), heating wattage, and evaporator fin spacing for dusty/coastal areas.
Why Our Unit Outperforms Standard Split Systems
In addition to the basic specifications, our engineering design places greater emphasis on durability and intelligent control, ensuring that your project remains competitive.
Stable COP > 3.8:Intelligent defrost algorithm adjusts to humidity, even in seaside areas.
BAS Integration:Optional Modbus/RS485 protocol allows remote monitoring of thecustom built-in pumpperformance and tank temperature.
