Plinth  convectors «Термія» for the  liquid systems of heating consist of a heat exchanger and a case. The heat exchanger is made of copper tubes on which aluminium plates (lamellas) are fixed by the method of forced fit.   Application of metals with high coefficient of convective heat exchange in the heat exchanger allows to use the devices effectively even in low-temperature  heating systems.

Front and upper panels of the case are made of extruded aluminium profile ensuring high uniform convective heat exchange along the full length of the heater.

Plinth convectors are placed along lower part of the room walls. The system designed on the basis of the plinth convectors makes it possible to warm-up quickly the floor, the lower part of the room volume. The heating system principle of operation excludes incompletely warmed-up, stagnent zones in the volume of the room, prevents damp emergence and condensate appearance on the walls of the room (fungus, mould), it is ideal for heating the rooms with high ceilings and considerable area of glazing, for country-houses (especially standing by themselves), covered swimming-pools and etc.  

Low linear density of the heat flow of the system elements allows to place furniture without fear of overheated areas formation when the heating device is shaded. 

The system is designed in the normal order using the well-known value of heat losses of the room. The heat exchanger heat rating is 240 W per 1 m of the length at the heat flow 70° C. The active part of the system of the plinth heating is calculated by dividing the value of the heat losses of the room by the value of the heat exchanger heat rating. The remaining part of the system structural length must be replaced  by a passive heat exchanger (two copper tubes 12 mm in diameter).

The recommended method of connection of active and passive parts of the heat exchanger is standard soldering with soft solder. The active parts of the heat exchanger should be arranged along the exterior walls of the room and under the windows. The passive parts – along the remaining full length of the system.

Standard thermoheads ,corresponding to the set up thermal valve, are used for the system automation, for example, of the Danfoss firm (RTD Inova 3130 or RTD Inova 3132). The thermoheads with a carried out sensor are preferred. Arrangement  of the carried out sensor at a man's  height allows to create the most comfortable conditions for a man to stay  in the room.

The surface of the devices is protected by the resistant  to mechanical action coating which is made using powder-polymer technology. Standard colour  is according to the catalogue of standard tints RAL –snow –white (RAL-9003).
