FIELD: heating. ^ SUBSTANCE: room heater includes heat exchanger installed in jacket and fixing supports connected to heat exchanger and jacket. Every support is arranged with at least one part that protrudes above the heat exchanger and interacts with internal surface of jacket. Protruding part of support is installed between internal surface of jacket and heat exchanger and is located along the perimeter of jacket internal surface. Additional air duct may be provided between support and adjacent side wall, which is formed by jacket side wall and extreme parts of top and bottom walls with corresponding air exhaust and intake openings in it. At that in one or two additional air ducts elements might be installed for connection of heat exchanger to heating conduit. At least one air choke may be installed between supports for closure of air exhaust or intake openings. Air filter is fixed to the air choke. Air supercharger is installed in the jacket. Room heater jacket contains casing with bottom, top and side walls. In casing in one of the walls or in all these walls closed apertures are arranged for heating conduits. Every closed aperture is formed by one continuous deepening arranged on internal side of jacket or by several continuous deepenings in jacket wall, which are arranged along aperture perimeter. In idle condition of jacket aperture is fully closed by part of jacket wall limited by perimeter of deepenings, and in working condition aperture is formed by mentioned deepenings along their perimeter. Jacket may be made of transparent material with source of light provided in its cavity. Heat exchanger contains tubular sections connected between each other, every of which includes bottom and top tubular segments connected with vertical tubular segment. Between every pair of adjacent sections in points of their connection to each other, heat exchanging element made of plate is fixed. In heat exchanger ends there are more heat exchanging elements installed that are made of other plates and serve as heat exchanger supports. One end of every additional heat exchanging element has facility for its connection with load bearing element of heated room. The other end of additional heat exchanging element plate is arranged with working surface for its contact with heater jacket. Dimensions of every heat exchanging element installed between heat exchanger sections are less than dimensions of additional heat exchanging element. ^ EFFECT: reduction of expenses for manufacture and increase of air draught in room heater. ^ 20 cl, 37 dwg |
