Energy from the air can be used as an alternative or additional heat source with the ecoGEO+ heat pumps in installations where geothermal capture (ground loops) is restricted or not possible.

​

The domestic AU range offers exceptional performance in the production of heating, cooling and hot water combined with the ecoGEO+ Basic and Compact heat pumps.

Domestic: Outdoor Air Unit (AU)

Works with ecoGEO+ heat pumps 

​

​​

​

  • Unique defrost system

  • Remotely controlled through My Ecoforest

  • Single phase power supply

  • Long lifespan

  • Fully hydraulic installation 

  • No limitation on distance from outdoor unit to heat pump

  • Hybrid installation including optional combination with ground source collection

  • Eliminates the need for boreholes 

6 kW | 12 kW | 22 kW​

This range of outdoor units is ideal for commercial installations with power ranges of 50kW-150kW. Combined with the ecoGEO+ HP (High Power) heat pumps, these Air Units can lower the cost of the system and provide more versatile and efficient installations.

  • Where is a ground source heat pump used?
    ecoGEO+ heat pumps can be used in a variety of applications from a small home to a large commercial project. The power output ranges from 1kW to 100kW with the ability to cascade up to 3 units (66kW capacity) in the domestic range and 6 units with the High Power range (up to 600kW capacity).
  • What water temperature does an ecoGEO+ heat pump produce?
    ecoGEO heat pumps deliver water up to 60°C for heating services and up to 70°C through HTR for domestic hot water and/or pool heating when the heat pump is running. The new PRO range with natural refrigerant can deliver 70°C through its production/heating service.
  • Can an ecoGEO+ heat pump deliver different water temperatures simultaneously?
    Up to four heating or cooling services can be managed at once – fan coil units (50°C), radiators (60°C), underfloor heating (35°C) and pool heating (40°C). If the system also delivers domestic hot water, this works through HTR (waste heat recovery) while the machine is running if needed. The ecoGEO heat pumps also have a reversing valve to deliver active cooling down to 7°C.
  • Is a buffer tank required with all installations?
    A buffer tank is not always required as you can directly connect to the heat pump. There are some applications where a buffer tank is recommended.
  • Is it possible to heat your pool or spa?
    Pool/spa heating can be delivered with an ecoGEO+ heat pump via HTR (heat recovery) or the production service. This is normally done through a titanium plate heat exchanger.
  • What is HTR technology?
    HTR refers to heat recovery which means that while the heat pump is running it can deliver domestic hot water and/or pool heating from waste heat produced.
  • Do I need a ground loop with the ecoGEO+ heat pump?
    There are three options to connect to an ecoGEO+ heat pump. A full geothermal system (ground or pond loop), aerothermal (with AU unit) or hybrid solution (combination of ground loop and aerothermal).
