Mechanical ventilation with heat recovery https://ecostream.org.uk/products/ is a highly efficient technology that significantly reduces energy consumption in building. Traditional ventilation methods, based on natural air circulation or simple exhaust systems, require large amounts of energy to maintain comfortable indoor conditions. While mechanical ventilation uses energy to drive fans, a heat recovery system can significantly reduce heat loss by returning heat from the exhaust air to the air entering the room. This allows you to significantly reduce heating energy consumption in winter and air conditioning in summer.
