The installation of a heat exchanger in the animal house systems can counteract the rising energy prices, it will save an average of 55% of gas consumption (depending on the type of stable, insulation, season, animal occupancy, and ventilation system). In addition to the savings in heating costs, the heat exchanger helps to improve air quality in the animal house because of the reduced humidity. Furthermore, such a system is environmentally friendly and serves the general environmental improvement. The considerable savings in gas consumption leads to a significant reduction of CO2 emissions and therefore counteracts climate change.
