Water-to-water

Gas Fired Absorption Heat Pump (Ground Source)

 

For Heating, Cooling and DHW production simultaneously.

Benefits

  • The heat pump benefits from Robur's Summer Rebate for the USA.
  • Geothermal loop reduction up to 40% compared to the best electric water-water heat pumps.
  • Ultra efficiency unit: efficiency over 125% recovering up to 28% of renewable energy from ground.
  • Simultaneous year-round heating, DHW and cooling production with a single machine.
  • The prevailing use of gas reduces the need of electric power by approximately 91% in comparison with electric compression units (0.4 electrical kW for 119,400 BTU/h heating and 46,100 BTU/h cooling).
  • Complete flexibility and modularity to increase seasonal performance factor and total heating and cooling capacity.
  • Single Phase Power.
  • No need to increase electric power demand.
  • For application requiring standby power, the electric generator size and electric output will be lower.
  • High Reliability due to few moving parts inside the unit.
  • Easy Maintenance, similar to gas fired boilers.
  • No use of Harmful Refrigerants.
  • Indoor Installation.

Applications

RESIDENTIAL and COMMERCIAL hydronic geothermal heating and cooling systems:

  • radiant floor or ceiling;
  • fan coil and air handlers;
  • cast iron radiators;
  • year-round DHW production;
  • free or active cooling mode available.

INDUSTRIAL applications with high year-round heating and cooling demand:

  • air handlers unit, A.T.U.;
  • ice storage.
