GSHP ground source heat pump 9 MR 7600538

Versatile heating and cooling solution for demanding installations

The GSHP 9 MR ground source heat pump is an advanced glycol/water or water/water type device that provides efficient heating and cooling year-round. By utilizing the stable ground temperature as an energy source, the system guarantees high efficiency even during the winter period, when other solutions lose performance.

Advanced design and reliable components

The heart of the device is a high-performance hermetic scroll compressor, which, in combination with plate heat exchangers (condenser and evaporator), ensures optimal heat exchange. The system includes a complete set of protections: an expansion valve, a filter dryer, low and high-pressure pressure switches, and a 4-way reversing valve enabling switching between heating and cooling modes.

Electronic soft starter protects the electrical installation from current surges during startup. Two high energy efficiency circulation pumps (EEI<0,23) serve the primary (source) and secondary (heating) circuits, ensuring optimal medium flow.

Intelligent control and operational safety

The DIEMATIC iSystem controller serves as the management center for the entire heating installation. It enables precise control of the heat pump's operation and control of up to three heating circuits, the domestic hot water (DHW) circulation pump, and cooling functions. The system automatically optimizes device operation depending on external conditions and building needs.

Operational safety is ensured by: an electronic pressure gauge for the hydraulic system, a safety valve, an air vent, and a flow meter on the heating circuit side. A flow sensor on the lower source side monitors the correctness of energy extraction from the ground.

Operating parameters and conditions

The device operates in a wide temperature range: in heating mode +7°C to +80°C for the water circuit and -15°C to +35°C for the ground collector. In cooling mode, it provides temperatures of +7°C to +25°C for the water and maintains full functionality at collector temperatures of -15°C to +35°C.

The maximum working pressure is 3 bar in both the heating circuit and the collector, guaranteeing safe system operation under various installation configurations. Single-phase power supply (230V) of the MR model adapts to standard domestic installations.

Completeness of delivery and technical support

The standard set includes a 10-liter expansion vessel on the primary (source) side and a second one on the secondary (heating) side, sound-insulating material reducing noise during operation, and a heating/DHW switching valve. An auxiliary electric heater kit and additional circulation pumps for higher capacities are available as options.

The system is covered by a 5-year manufacturer's warranty, emphasizing the reliability of the design and long-term operational stability.
