Fireplace and recuperation?<\/div><\/div><\/div>
<\/div><\/div><\/div><\/div>

According to the new Technical Conditions (WT2021), from January 1, 2021, a system regulating the air circulation in the building by means of mechanical ventilation or recuperation will be a mandatory element of newly built houses. This is due to an energy-saving and ecological approach. At the same time, a large number of investors dream of a home fireplace in the form of a fireplace. It turns out that one does not necessarily exclude the other. It is enough to use a fireplace \/ freestanding stove adapted to this type of systems!<\/p>\n<\/div><\/div><\/div><\/div>

What is recuperation?<\/strong>
Heat recovery is the exchange of air with simultaneous heat recovery. In ventilation, the device controlling this process is a heat recovery unit (HRV) \u2013 an electrical device that ensures air exchange within a building by exhausting stale air while simultaneously supplying freshly filtered air. During this exchange, the HRV warms the supply air via a built-in heat exchanger, utilizing the heat from the exhaust air, thereby recovering heat within the building.<\/p>\n

Fireplaces in the house with recuperation?<\/strong>
In order for a fireplace \/ free-standing stove to work in a house with recuperation, it must have a closed combustion chamber with its own air supply from the outside. Outdoor air is usually supplied through pipes under the floor, which are designed to supply fresh air from outside the house to the fireplace so that the fireplace does not draw air from the room in which it is located. Such a fireplace insert, properly installed, together with a recuperator is able to provide adequate thermal comfort without affecting the operation of the installation. Before buying, it is worth checking whether a given insert \/ free-standing stove has a manufacturer's declaration that it is suitable for use in this type of systems.<\/p>\n

ATTENTION!<\/strong> In the case of fireplaces without a closed combustion chamber and fireplaces that take air from the room, there is a very high risk of smoke blowing out the fireplace (by drawing air through the recuperator), which in turn may lead to the risk of sooting. Such systems cannot function properly with such systems.<\/p>\n

Advantages of a fireplace with recuperation?<\/strong>
heat recovery from the exhaust air (especially in winter, the rooms are not cooled with cold outside air, but heated by a recuperator);<\/p>\n
