Radiant heaters

This name can be used to describe heating elements that give off heat with a clear advantage of radiation over convection.. These are heating pipes placed near one of the partitions of heated rooms (most often theirs … read on

In addition to the presented simple solutions of convectors, so-called. fan climate coils (also called valves). They have a built-in fan that draws air from the outside or from the room, depending on the position of the damper … read on

There are a significant number of convector heaters. These also include Purmo type radiators, manufactured from steel sheet with a thickness of 1,25 mm and convection elements with a thickness 0,5 Mm. There are three types … read on

Convector heaters

A convector is called a housingd heat exchanger that gives off the majority of heat by convection. This exchanger is most often copper tubes, on which the so-called. Slats, i.e. properly shaped ribs, … read on

One thermal efficiency of profiled panel radiators- (A) and double-row (B)

For the most common, of a double-row radiator, the nominal heat output is reduced by more than 35%, as shown in the picture. The basic elements are … read on

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 … read on

In closed water installations, member heaters made of aluminum may be used at a temperature lower than + 110 ° C, which are characterized by aesthetic shapes, they are light and have a low water capacity. if … read on

If the radiator is placed in a window niche, special attention should be paid to the appropriate distances from the window sill and from the floor. Too short a distance and the use of radiator housings can reduce this … read on

Sectional radiators

The largest group of solutions used in central heating installations are sectional radiators. They consist of identical members (also called cells) creating the desired heating surfaces. They belong to the group of heaters of the type … read on
