GAHP A

Air-to-water

Gas Fired Absorption Heat Pump

 

For Heating.

Benefits

  • The heat pump benefits from Robur's Summer Rebate for the USA and FortisBC's Rebate for British Columbia in Canada.
  • Ultra efficiency unit: efficiency over 129%, saving up to 40% in operational costs compared to best condensing boilers, recovering 38% of renewable energy from air.
  • Stable operation down to -20°F: efficiency over 100% even at –4 °F.
  • Complete flexibility and modularity to increase seasonal performance factor and total heating capacity.
  • The prevailing use of gas reduces the need of electric power by approximately 87% in comparison with electric compression units (0.9 electric kW for 123,500 BTU/h heating).
  • Suitable integration with condensing or standard boilers to increase the seasonal efficiency of the system.
  • Single Phase Power.
  • High Reliability due to few moving parts inside the unit.
  • Easy Maintenance, similar to gas fired boilers.
  • No Use of Harmful Refrigerants.
  • Outdoor Installation.
  • No Comfort Reduction during Defrosting Cycles: the unit supplies about 50% of the total heating capacity.

Applications
