Low-Noise 7kW 220V DC Inverter Ground Source Heat Pump
Low-Noise 7kW ground source heat pump
,220V DC inverter heat pump
,Ground source heat pump with warranty
Driven by a high-efficiency Mitsubishi DC inverter rotary compressor, the RFJ-WW-7DC dynamically adjusts output capacity to match real-time indoor thermal demand. This variable capacity regulation maintains stable room temperatures while eliminating energy waste from frequent start-stop cycles.
Features an intuitive 4.3-inch color screen controller paired with built-in WiFi connectivity for intelligent system management. Homeowners and property managers can monitor operational parameters, adjust temperature setpoints, and switch heating modes remotely via mobile app.
By tapping into constant underground thermal energy maintained between 4°C and 12°C year-round, this DC inverter heat pump cuts heating energy consumption by up to 60% and significantly reduces CO2 emissions compared to electric or gas boilers. Engineered with acoustically insulated housing, it operates at low noise levels for high indoor comfort.
Mitsubishi DC inverter rotary compressor, high-efficiency plate heat exchanger, 4.3-inch color screen controller, built-in WiFi module, and water flow control module.
- Heating-Only Configuration: Dedicated single-function thermal generator optimized for hydronic space heating
- External Pump Requirement: Unit is built without an internal circulation pump, giving system integrators complete flexibility to size external loop pumps
- Residential Hydronic Space Heating: Ideal for villas, modern homes, and apartments using underfloor radiant heating, hydronic radiators, or fan coil units
- Versatile Geothermal Ground Source Collectors: Compatible with four geothermal source loops: deep rock boreholes (90-200m depth), shallow ground water wells (4°C-12°C), lake collectors, or horizontal surface soil loops (80-100cm depth)
- Smart Eco-Friendly Energy Retrofits: Designed to replace traditional fossil-fuel or electric resistance heating with clean, renewable underground energy
