It is expedient to implement this measure for the recovery and efficient operation of the ventilation system and, first of all, to meet the sanitary and hygienic norms for human presence in the premises. With recovery of the ventilation system operation, the consumption of both heat and electric energy increases. Use of the recuperators allows the system to efficiently use the energy potential of the exhaust air, which is also used for pre-heating the incoming fresh air. To implement this measure, it is recommended to conduct an additional survey of the existing ventilation systems.

The cost of apartment-level recuperation is UAH 512,000. If the central ventilation system needs to be installed, the cost of the measure may reach UAH 300,000 or more.
