PURPOSE: A water passage system for heating water of an oil boiler is provided to maximally absorb heat in combustion heat by having an additional combustion chamber and absorbing combustion gas. CONSTITUTION: A combustion case(3) is composed of a combustion chamber(5) having an exhaust hole(4), and a water passage(6) absorbing heat radiated into the wall of the combustion chamber(5). A heat absorbing unit(14) is composed of water pipes(10a,10b,10c,10d) receiving combustion gas and absorbing heat, a distributor(11) guiding and distributing water, and a heat absorbing water passage case(13) having an exhaust port(12) absorbing the residual heat in the combustion gas.
