FIELD: heating equipment. SUBSTANCE: heating apparatus has power transformer, AC stabilizer, current transformers, heating members and beehive temperature regulators. Number of heating members corresponds to the number of beehives. AC stabilizer has current sensor, rectifier unit with filter, control unit, protection unit, controllable power regulator and current setter. Beehive temperature regulator has temperature sensor, temperature setter, amplifying circuit, power unit and shunting element. Apparatus is adapted for heating plurality of bee families by means of low-current circuit connected to secondary circuit of power transformer (one per 1 apiary) for breakage or short-circuit protection. Construction of heaters provides automatic setting of required current and voltage parameters. EFFECT: increased efficiency in setting required bee family keeping conditions. 4 dwg
