In Russian climatic conditions, unheated loggias play unless the decorative role, and also perform the functions of the warehouse of unnecessary things. In order to use these designs in the cold season, they need to warm them. How?

The only possible method of heating the pre-insulated loggias - with the help of electrical heaters (central water heating batteries are strictly prohibited from the residential premises). Since the area of loggia is small, then the load on the network will not be excessive.

Rational to install heaters that occupy a minimum place, for example, electric warm floors. Alternatively, it is possible to consider infrared ceiling heaters, but warm floors have a significant plus - "lower heating", which provides an optimal air temperature gradient indoor. Electric warm floors can almost instantly respond to the inclusion and disconnection of heating.
Warm floors are not recommended to be mounted in tangled loggias, where in the cold season there is no temperature difference between the outer and the inner air
In addition, many modern versions of the electrical systems offered for heating are very easy to install. The most noticeable advantage is manifested in small (1-2 m²) areas. There are ready-made solutions for them, for example, the film warm floors with a capacity of up to 220 W / m², which do not require the manufacture of screed, cable warm floor Unimat CORD with a power of up to 200 W / m², rod warm floor Unimat boost with a capacity of up to 160 W / m² . The use of electrical warm floors for heating the loggia has its own characteristics. Since the designs such as loggias are usually higher heat loss, then designers should first take care of high-quality insulation. And already "according to the results of insulation" to fulfill the calculation.
On average heat loss in the premises of multi-storey houses, 100 W / m² are 100 W / m². At balconies and loggias, with good heat and heat loss, approximately 120-140 W / m² are equal. They are recommended to mount warm floors with a specific power of 200-230 W / m² on an area of at least 95% of the total installation of the premises. At the same time, the air temperature on the balconies will be close to 21 ° C. If the loggias are badly insulated, then in addition to warm floors, it is desirable to install additionally heating appliances. In this case, we also recommend using warm floors with a specific power of 200-230 W / m² on an area of at least 80% of the general placement of the room.

WHAT IS GOOD AND WHAT IS BAD
To well-insulated loggias include those in which the air temperature inside the room at a street temperature of 0 ° C without additional heating is approximately 10-12 ° C. In poorly instended logs, the air temperature at a street temperature of 0 ° C without additional heating is 5 ° C. There are practically no difference in the temperature of the outer and internal air in tangled loggias.
