Abstract
The article deals with developing and analyzing a heat pipe of a low-pressure steam electric heater intended for autonomous heating systems. The object of the study is two types of heating elements: a tubular electric heater with a nichrome spiral and an induction heater. Experimental analysis methods have been used to evaluate the heating characteristics, the temperature distribution and the energy efficiency. It has been established that the induction heater provides a higher heating rate and uniform temperature distribution, while the tubular heater is characterized by stable operation and economy. The obtained results allow proposing the ways to optimize the design of the electric heater to increase its efficiency and reliability. The findings confirm the practical potential of using the devices under study in various types of heating systems.
