FIELD: heat supply. SUBSTANCE: boiler body has two closed circuits for heated water and intermediate heat-transfer agent. Use of a chemically inert element from the alkannic series (for instance, paraffin) and the two-circuit design of the boiler enhance the boiler efficiency, decrease the mass and dimensional indices. EFFECT: improved design. 2 cl, 3 dwg
