<P>PROBLEM TO BE SOLVED: To reduce the size of a latent heat recovery type heat source machine comprising a main heat exchanger for heating a heating medium, an auxiliary heat exchanger for recovering the latent heat of combustion exhaust gas, a cistern interposed in a heating circulation circuit, and the heating circulation circuit having the heating medium circulated therein and including heating going piping for guiding the heating medium heated by the main heat exchanger to a radiator, heating return piping for guiding the heating medium of which heat is released by the radiator to the auxiliary heat exchanger, first connection piping for guiding the heating medium of which latent heat is recovered by the auxiliary heat exchanger to the cistern and a bypass passage for guiding part of the heating medium made to flow in the heating going pipe to the cistern. <P>SOLUTION: An inflow port 84 is provided at an upper end of the cistern 8, and a downstream end of the first connection piping 73 is connected to the inflow port 84. Preferably, a guide pipe 85 for guiding the heating medium made to flow in from the inflow port 84 to the lower side from the lower end of a low water level electrode 81 arranged inside the cistern 8 is provided within the cistern 8. <P>COPYRIGHT: (C)2010,JPO&INPIT |
