FIELD: heating.SUBSTANCE: electric heater serving for heating, maintenance of temperature and circulation of fluid medium includes the following: the first main part 100 of the housing and the second protective part 200 of the housing, which can be connected to each other, thus forming internal chamber 300; the first fluid medium inlet hole 210; the second fluid medium outlet hole 220; an electric resistor; the first temperature sensor serving for change of working temperature; the second temperature sensor intended to prevent excess threshold of safe temperature; an electronic control unit. The first main part 100 of the housing includes an electric resistor heating the main part 100 of the housing and a sensor directly measuring the temperature of the main part 100 of the housing.EFFECT: resistor, the above first sensor and the above second sensor are connected to a control unit that maintains working temperature of the first main part 100 of the housing and prevents excess threshold of safe temperature.16 cl, 10 dwg |
