Description
All-Weather Thermal Stability & Defrost-Free Winter Heating
Unlike air-source systems that suffer severe efficiency loss and thermal drop-offs during freeze cycles, the RFJ-WW-10DC geothermal heat pump draws heat from stable subsoil energy sources (4°C to 12°C). By eliminating energy-draining outdoor defrost cycles, this 10 kW ground-source unit maintains an exceptionally high seasonal COP and consistent heating output regardless of sub-zero ambient air temperatures.
Acoustic-Optimized Cabinet & Low-Vibration Engineering
Engineered specifically for noise-sensitive residential environments, the unit pairs a low-vibration Mitsubishi DC inverter compressor with sound-dampened internal casing and dampening mounts. The variable-speed drive smoothly ramps motor speed up and down, preventing the loud mechanical torque shocks and acoustic spikes typical of traditional fixed-speed on/off heat pumps.
Architectural Hydronic Versatility & Unrestricted Hydraulic Design
Manufactured without an internal water pump, the RFJ-WW-10DC gives MEP engineers and hydronic installers complete design freedom. External circulating pumps can be precisely specified and matched to the exact friction losses, pipe lengths, and flow rates of the specific ground loop array, underfloor heating manifolds, fan coil units, or domestic hot water buffer tanks.
Applications
Medium-to-Large Residential Villas
Provides efficient 10 kW hydronic radiant floor heating and domestic hot water for single-family residences ranging from 100 m² to 160 m².
Smart Home Energy Upgrades
Replaces legacy gas or oil boilers in suburban housing developments with an app-controlled, low-carbon geothermal heating solution.
Versatile Ground Loop Arrays
Connects seamlessly with vertical rock boreholes (90–200m depth), horizontal soil collector grids, groundwater wells, or lake loop heat exchangers.
