A heating electric boiler has a heat exchanger with input and output, tubular electric heaters, circulation pump, control block. Additionally it has a circulation chamber with inlet and outlet openings connected to heat exchanger and circulation pump connected to control block. The heat exchanger has a horizontal partition that is placed in its lower part under tubular electric heaters connected to block, fixed to flange of the block of tubular electric heaters on which additionally are fixed: a tube with sensor of liquid temperature that is placed in vertical position in the upper section of the block of tubular electric heaters at distance from tubular electric heaters and a tube with sensor of temperature of tubular electric heaters that is placed in vertical position, and with its bent lower part it is connected to the lower parts of the tubular electric heaters that are connected together with temperature sensors to the control block. The heat exchanger has as well a transition channel that connects its input to output opening of the circulation chamber, and input of heating system is placed in the lower part of the article. |
