FIELD: heating.
SUBSTANCE: invention relates to electric heaters, preferably using a electric simulation of nuclear fuel rods to be connected in assembly in power reactors. Device (1) for heating of liquid (Liq.) with increased heat flow includes tubular resistor (2) fed with direct current to heat the liquid due to heat conductivity through embraced by direct mechanical contact electrically insulating and heat conducting intermediate element (6, 22), the complex tubular resistor/intermediate element is surrounded by a cover (7) intended for submersion into a heated liquid, at least part of its length.
EFFECT: device provides creation of uniform heat flow, reliable in operation and has long service life.
