<p>The tube radiator (1) has heating tubes (2) with profile with front side and a rear side section, whereby the front side section constructed from a front face and parallel side faces is narrower than the rear side section so that the latter has a minimum distance from the front side section of the adjacent profile, while the rear side section is constructed wider and has at least one edge which creates a minimum distance to the rear side section of the adjacent profile.</p> |
