The invention relates to heat engineering and can be used in heating radiators. The radiator comprises a set of consecutively connected main sections and one end section, all of which comprise two parallel transverse portions situated at opposite ends and having straight channels. The end section also comprises a longitudinal portion for the passage of a heat transfer agent, which connects the transverse portions. Each of the sections comprises an intermediate partition which connects the transverse portions and is perpendicular thereto. The longitudinal portion passes through the middle part of the end section. The intermediate partitions of the main sections are solid. The radiator is mounted on supports. Each of the supports comprises a stand with a foot, and a crosspiece which is rigidly fastened to the opposite end of the stand. The technical result is an increase in the range of hot water heating means.
