Heat Pump ecoGEO + Air Unit

Aerothermal unit that allows ecoGEO heat pumps to use external air as source of energy. 

In installations where the geothermal option is limited or not available, the air units AU are the solution. This units allows the ecoGEO heat pumps to use external air as source of energy.

The Air Unit is equipped with a very silent and highly efficient axial Ziehl-Abegg fan(s), that with our exclusive defrost technology allows to significantly increase the seasonal performance factor (SPF). This system completely eliminates the idle times of the heat pump during defrost cycle, because isn't necessary to invert the refrigerant cycle or to activate external electrical heaters during the process.

* Ecoforest defrost cycle is only available in models B2, B4, C2 and C4 of the ecoGEO domestic range. 
** Ideal for domestic or industrial installations where the geothermal option is limited or not available.

The Ecoforest group was founded in Vigo in 1959 at the hands of its owner and founder Jose Carlos Alonso Martínez, specializing in the heating sector. In 1993, Ecoforest became the first European manufacturer of pellet hydro stoves, bringing to the market a new, ecological and economic product.

Currently, Ecoforest is the leading company in the market with the widest range of pellet stoves and boilers. In 2012, Ecoforest decided to bet in another innovative technology and launched its first ground source heat pump to the market, being the only Spanish manufacturer of this product and the most specialized in inverter technology on the planet.

The R&D department of Ecoforest continues to innovate every day, in order to develop more advanced and more efficient products. Currently Ecoforest products can be found in more than 30 countries around the world.
