FIELD: heating systems. SUBSTANCE: proposed radiator includes housing consisting of first blind section 1 and intermediate through sections 2 and last section 3 with hubs 5 interconnected by means of welding over inner and outer beads 8 and 10 received by each other and over holes in hubs 5. Welded in holes of last section 3 are blanks 11 and 13 with electric heating element 12 available in one of them; other blank is provided with nut 14 having plug 15 for filling housing with oil. Last section 3 is provided with control unit 17 having thermostatic switch 18. Power is supplied through cord 26. Innovation of invention consists in making control unit 17 from intermediate section whose inner beads 18 are welded to outer beads 10 available over contour of inlet holes 7 in hubs 5 of last stage 3. Outlet holes in control unit 17 are closed by covers 23 through sealant. Cord 26 is introduced into section through sealing bush 27. EFFECT: enhanced tightness of radiator; complete proofness and fire safety. 4 cl, 1 dwg
