A device for heating liquid has closed hydraulic contour in which in sequence are installed pump with electric motor, expansion tank that has piston, device for its displacement and draining valve, filling nozzle, cavitator, sensors of temperature and pressure and heat exchanger. In hydraulic contour upstream of cavitator in sequence are placed temperature sensor and permanent magnet, and downstream of the pump a flow rate meter is installed. The cavitator has cavitometer and counter of number of bubbles that has photoelectric multiplier. |
