CGW-IU A1 • A2W heat pumps R32 hydromodule

Air/water inverter controlled heat pump with R32 refrigerant. Thanks to the advanced heat pump technology, the energy from the outside air is absorbed and transferred to the water for heating and cooling of the home and the domestic hot water.
The intelligent control of the compressor and expansion valve ensures a precise and fast control of the water temperature, thus reducing the energy consumption.

Brand

  • R-AQUA

Application

  • Heating of new or existing houses
  • Heating by means of radiators, convectors or floor, wall or ceiling heating
  • Cooling by means of convectors, floor, wall or ceiling cooling
  • Production of domestic hot water, provided a hot water heater is installed

Composition

  • 3-way valve
  • Communication cable included
  • High efficiency plate heat exchanger
  • Energy-efficient circulation pump

  • Colour touch screen controller (wired)

  • Expansion vessel (10 liters)
  • Safety valve (3 bar)
  • Electrical backup heater
  • Water pressure sensor

Refrigerant

  • R32

Specifications

  • Split system
  • 1 device for heating, cooling and domestic hot water
    • Heating assured at outside temperatures down to -25°C
    • Water temperature up to 55°C at outside temperatures down to -10°C
  • A+++ at 35°C water temperature
  • Bivalent setup possible

      • The heat pump will send a signal to an external heat source (eg gas boiler) depending on the outside temperature. This causes the heat pump stoped, and the second source present will provide the heating.
