FIELD: heating systems. ^ SUBSTANCE: heat generation method applied for heating buildings and structures includes pumping of heat carrier under pressure that eliminates cavitation in heat carrier flow. The heating device contains heat energy generator and consumer heat supply system, which are connected to each other in the form of a closed circuit by means of supply and return pipelines, at least one circulation pump located in that circuit and at least one recirculation pump installed with straight and return pipelines. At least one above recirculation pump includes at least one element containing a confuser, a diffuser and at least one annular groove made between the diffuser and the confuser. According to the invention, at least some part of the supply pipeline, which is located in front of heat energy generator and/or at least some part of recirculation pipeline after the above element containing a confuser, a diffuser and at least one annular groove, are subject to pulsating electromagnetic / or acoustic fields. ^ EFFECT: high fuel economy. ^ 14 cl, 6 dwg |
