PURPOSE: A vent drain switching unit for heat storage combustion system is provided to facilitate pipe distribution and operation by switching combustion air and combustion exhaust gas using two switching barrel and attachments thereof. CONSTITUTION: A vent drain switching unit for heat storage combustion system comprises a first cylindrical switching barrel(4a) and a second cylindrical switching barrel. The first switching barrel includes a cylinder(6) therein movable by an air cylinder(7), two supply opening(8) thereon connected with a burner body(1) with a pipe, and a circular vent drain channel(5) integrally formed with a combustion supply opening(10) to which combustion air is supplied. The second switching barrel includes a cylinder therein movable by an air cylinder, two drain opening(9) thereon connected with the burner body with a pipe, and a circular vent drain channel integrally formed with a combustion drain opening(11) for discharging combustion exhaust gas.
