Abstract

PURPOSE: To prevent destruction of a heat exchanger due to freezing, by providing a float valve, a valve seat for sealing it, a float receiver, and a spring for connecting them at the outlet side of a temperature regulating knob in a by-pass passage.
CONSTITUTION: At the outlet side of the temperature regulating knob 3 in the by- pass passage 4 are arranged the float valve 6, the valve seat 7, the float receiver 8 and the spring 9 for connecting them. With the hot water temperature regulating knob of the water body 1 being opened, when the ambient temperature has become below freezing point, and a low temperature actuating valve 2 is actuated to let water flow, as there is a little water, the water pressure difference is small, and due to the action of the spring 9 the float valve 6 is engaged with the valve seat 7 to seal the float valve. Accordingly, since all the water that has passed through the water body 1 is withdrawn through the low temperature actuating valve 2 via a het exchanger 5, destruction of the heat exchanger 5 due to freezing can be prevented even when the temperature has lowered below freezing temperature.
