ABSTRACT:
A heat exchanger wherein an upright insulated outer jacket contains a body of relatively cold liquid and spacedly surrounds an upright hollow cylindrical heat conducting body which, in turn, spacedly surrounds a helical heating body confining a flowing heating medium. The upper and lower ends of the heat conducting body are open so that cold liquid can enter the heat conducting body from below to exchange heat with the medium in the helical heating body, to thereby rise in the heat conducting body, and to issue at the upper end of the heat conducting body. The upper end of the heat conducting body has a flow restrictor which defines an outlet opening for the heated liquid. An electric heater can be installed in the outer jacket to heat the liquid when the supply of warmer medium is insufficient.
