Modern building become more and more tighten insulated. This makes the mechanical ventilation obligatory, in order to ensure health and comfort of the inhabitants.
Traditionally, ventilation and air-conditioning equipment are the biggest energy consumers in buildings. This fact impose the use of heat recovery equipment that could reduce the running costs significantly. Depending of the type of recovery, those units have efficiency up to 80%. The need of additional heating and cooling is reduced and that is of high economical and environmental importance.
Heat recovery ventilation is exceptionally profitable investment and has a payback period of approximately 1-3 years, depending on the running hours of the system and regional climate.
