Air source: Domestic AU range

Air source: Domestic AU range

The combination of our ecoGEO heat pumps and our outdoor air units (AU) is an entirely different way to make aerothermal energy using the high performance and unique characteristics of our ecoGEO but in a more affordable way. This type of installation can substitutes or complement the geothermal wells as a method of capture by one or more aerothermal units (AU). In this way we get to use the energy of the air to produce ACS, heating and cooling. It should also be noted that with this type of aerothermal energy we have access to the HGE technology of the ecoGEO.

Domestic AU range, a better way to make aerothermmal energy

AU range is a unique aerothermal unit. Unlike all other products on the market, the AU can be used as a source of capture for our ecoGEO heat pumps, replacing or even complementing the geothermal capture (Ecoforest exclusive hybridization) in installations where geothermal drilling is either not possible or restricted.

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.
