Plate heaters (flat) part 1

Plate heaters (flat)

The first panel radiators appeared in 20. in the twentieth century and these were steel radiators. Development of production automation, and, above all, welding technique, in the middle of the last century caused a jump in their production. Currently, their share exceeds 90% the entire number of types of radiators used. Thanks to the shallow depth and relatively large heat exchange surface (smooth or profiled) they are a light structure with low water capacity, working well with low parameters of heating systems. They are covered with high-quality varnish coatings. They satisfy in terms of aesthetics and decoration. Plate heaters, in solutions similar to tubular heaters, are made of steel sheet with a thickness 2-4 Mm, the thickness of the entire board is approx 25 Mm. There may be one solution- or multi-row (see diagrams in the picture).

It is also possible to mount any number of panels vertically. The front surface of these radiators gives off heat by radiation and convection, and the back side — mainly on the principle of convection. Such heaters have been used in the country for years 70. TWENTIETH CENTURY. Thermal efficiency of radiators (with smooth and profiled surfaces) is usually proportional to their height. When placing these radiators one above the other, the heat output is similar to a single radiator with a total height.
