Abstract: A heating assembly for heating a liquid storage tank includes a heat exchanger tank supported in one wall of the storage tank to extend into the storage tank in contact with liquid stored therein. The heat exchanger tank contains a heat exchanger fluid therein which is heated by a burner tube extending through the heat exchanger tank whereby heat is only transferred to the liquid in the storage tank through the heat exchanger fluid. A controller actuates the burner head of the burner tube to maintain temperature of the heat exchanger fluid between upper and lower temperature limits. The operation of the burner head is interrupted in response to temperature of the liquid in the storage tank exceeding an upper limit, or fluid level in the heat exchanger tank being below a lower limit as determined by respective sensors.
