Indirect tubular air heaters - reliable operation, easy maintenance

Tubular air heating elements are inserted into the heating flange made of special steel and enamelled against corrosion. Compared to conventional immersion heating elements, the advantages of indirect heating element are as follows:
  • heaters are not in direct contact with water,
  • the replacement of heating elements is simple as it is not required to empty the water heater before repair, ,
  • the heating flange incorporates 2 or more heating elements electrically connected in parallel, assuring a higher reliability of operation (if one heating element fails, the water heater still operates),
  • the limestone depositing is reduced and removing the limestone deposit is simpler,
  • the inside surface is completely enamel coated (no blank surfaces, compared to the models with immersion heating elements) therefore Mg anode consumption is reduced and consequently its life span is longer.
