20kW 380V Eco-Friendly Geothermal Water-to-Water Heat Pump
20kW geothermal heat pump
,380V water-to-water heat pump
,eco-friendly ground source heat pump
By tapping into constant underground thermal energy maintained between 4°C and 12°C year-round, this geothermal heat pump delivers clean space heating while reducing energy consumption by up to 60% compared to electric or gas boilers. It transfers natural heat absorbed from the earth into hydronic heating systems, significantly cutting household carbon emissions.
Powered by a high-efficiency Gree rotary compressor operating on 380V/3Ph power, this geothermal heat pump provides robust 20 kW thermal output. The industrial-grade motor architecture delivers stable, quiet performance under continuous hydronic heating loads.
Featuring high-efficiency brazed plate heat exchangers on both ground-source and load sides, this geothermal heat pump optimizes heat transfer across closed or open loops. An integrated water flow switch prevents low-flow damage, while the pump-free casing design allows system integrators to size external circulating pumps tailored to specific pipe lengths and head pressure requirements.
- Standard Included Components: Gree rotary compressor, dual brazed plate heat exchangers, built-in water flow protection switch, and simplified digital controller.
- System Design Notes:
- Heating-Only Configuration: Dedicated single-function thermal generator engineered for hydronic space heating.
- External Pump Requirement: Built without an internal circulating pump, giving engineers full flexibility to integrate external pump units.
- Commercial & Multi-Family Space Heating: Ideal for large villas, commercial offices, and agricultural facilities utilizing underfloor radiant heating grids, hydronic radiators, or fan coil units.
- Versatile Geothermal Ground Loops: Connects to four main geothermal sources: vertical rock boreholes (90-200m depth), shallow ground water wells, lake water circuits, or horizontal surface soil loops (80-100cm depth).
- Green Energy Building Upgrades: Replaces fossil-fuel boilers or electric heaters to drastically reduce seasonal heating bills and carbon footprint.
