Abstract
Abstract A heating system comprises a hydraulic pump, a heat generating chamber, and a driving means for said hydraulic pump, and besides some pipes provided therebetween for connecting them into a closed loop. An orifice is provided at the inlet of said heat generating chamber. Said pipes are filled with a kind of liquid such as oil etc. in advance. Said liquid is forced to be circulated in said pipes through each component, being driven by means of said hydraulic pump wherein the pressed liquid is jetted out into said heat generating chamber through said orifice. Thus, the loss hydraulic energy due to jetting out of the hydraulic liquid will be converted into heat energy which can be utilized as the heat source of said heating system.
