Conventional ventilation loses the heat and coolness that you produce inside with climate systems, and that you pay for. These "heat losses" significantly increase your energy bills.

Unlike conventional ventilation, the VT501 recuperator has a ceramic core inside, which maintains a stable temperature in the room, despite the operation of the ventilation, which drastically reduces such heat losses. In recuperation mode, first, the old air is blown out of the room for 65 seconds, and then the new fresh air is blown into the room for 65 seconds. At the same time, the cold air, blown out of the room in summer, cools the ceramic core, and then the hot outdoor air, passing through the ceramic core cooled into the house, cools down. And vice versa in winter.

For example, if it is +25 inside the house and +35 outside, then with normal ventilation you have to spend energy on cooling the outside air by 10 degrees. The air that is supplied to the house by the recuperator will cool down when passing through the ceramic heat exchanger and will enter the house already cooled to 27-28 degrees. Therefore, your fresh air cooling costs will be several times less, and the air will already be free of dust and insects. Similarly, in winter, fresh cold air from the outside will be heated by a ceramic heat exchanger, reducing your heating costs.

Low energy consumption during operation, reduced power of climate systems needed, as well as relatively low installation costs make it possible to create economical ventilation of the building, both in terms of equipment cost and maintenance.
