2016 New Design Electric Water Heater Electric Heaters Comparison

Tubular heating elements perform exceptional heat transfer by conduction, convection or radiation to heat liquids, air, gases and surfaces. Tubular heating elements are also used for radiant heating in open air or in vacuum atmospheres;
It is the most versatile heating appliance among all electric heating elements.In most heater assemblies, tubular element design configurations vary — round, triangular, flat press and formed.
