The disadvantage is that it requires two types of energy sources - low pressure steam and electric current, which together makes the construction complicated and inefficient.
The closest analogue is a device to produce thermal energy, consisting of a body, tank, high pressure pump, motor, magnetostrictor, high-pressure pipelines. (Patent of Russian Federation №2254524, CL F24G, 3/00, publ. in bull. No. 17, 20.06.2005,)
The disadvantage is the closest analogue is the large power consumption and design complexity.
The purpose of the invention is to increase the heating efficiency of the working environment (i.e. coolant) and the reduction of energy consumption.
