PURPOSE: A water circulation device using a bypass tank is provided to reduce the time for heating a hot water mat and to prevent the heat energy loss by serially connecting to a pump. CONSTITUTION: A water circulation device using a bypass tank comprises a water tank(1) and a bypass tank(10). The bypass tank is connected to the water tank through a supply pipe(11) on top of a supply pipe of the bypass tank. An air outlet(12) is extended to top of the water tank from the top of a water inlet(10a) of the bypass tank. A water supply pipe of a heating pipe(6) is connected to the water inlet of the bypass tank. The water supply pipe of the by-pass tank is connected to the water inlet of a pump(2) through a tube(3). |
