Ground-water heat pump DUAL 22 kW

— reliable and environmentally friendly solution

Geothermal heat pump DUAL 22 kW represents one of the most advanced solutions for heating, cooling and domestic hot water (DHW). This system is designed to ensure maximum reliability and high performance in all conditions.

Main features of the system

Ground-to-water heat pump DUAL 22 kW in two-module configuration:

• The first module, with a power of 11 kW, performs heating, cooling and DHW functions.
• The second module, with a power of 11 kW, handles heating and cooling, expanding the functionality of the system.
• The total power of the system is 22 kWTwo compressors allow simultaneous operation in different modes — for example, heating and DHW or cooling and DHW.
• The modules are completely interchangeable, and operating modes can be changed from the controller menu.
• The system's lifespan increases by two times.

Energy efficiency:

• Stable power of stationary compressors: 11 kW for each module.
• The energy efficiency coefficient (COP) reaches 4,57, significantly reducing operating costs.

Ecology:

• Choosing environmentally friendly refrigerants: R417A, R1234ze or R290These refrigerants are environmentally safe and meet modern standards.
• High leaving water temperature:
  • Ground-water heat pump DUAL 22 kW with refrigerant R417A: up to +60°C.
  • Ground-water heat pump DUAL 22 kW with refrigerant R1234ze: up to +65°C.
  • Ground-water heat pump DUAL 22 kW with refrigerant R290: up to +70°C for heating and up to +75°C for DHW.
• No additional electric heating elements are required to increase the water temperature.
• The use of geothermal energy allows for the reduction of the carbon footprint and the extraction of up to 75% from energy from renewable resources.

Flexibility in installation:

• The compact housing of the heat pump facilitates installation even in confined spaces.

Benefits of geothermal heat pumps DUAL 22 kW

1. High reliability:
   • The dual-compressor construction ensures stable and durable operation even under heavy use.
2. Wide operating temperature range:
   • It is effective at outdoor temperatures between -50°C and +45°C.
3. Versatility in use:
   • The DUAL 22 kW geothermal heat pump is suitable for heating, cooling and DHW in private homes, offices and commercial properties with an area of ​​up to 320 m².
4. Silent operation:
   • The noise level below 50 dB makes the pump almost imperceptible in residential or work areas.
5. Simultaneous operation in different modes:
   • For example, it can simultaneously heat spaces and produce hot water for domestic hot water.
6. Economy:
   • High efficiency helps reduce heating and cooling costs.
