GBFU EDD

Pressurised electric water heaters
  • Volumes: 50, 80, 100, 120 and 150l.
  • Smaller external diameter (ø 454).
  • Vertical or horizontal wall mounting.
  • High – quality thermal insulation.
  • Indirect air heating element.
  • Tank made of high quality steel sheet, enamel coated at 850°C.
  • Magnesium anode for additional anti-corrosion protection of tank.
  • Large diameter of heating flange (100 mm) allows simple cleaning and maintenance.

Electronic controller

  • Mg anode consumption measurement.
  • Electrical heating element operation indicator.
  • Temperature range adjustment 35°C to 75°C (accuracy 1°C).
  • Temperature selection (menu button):
    • arbitrary temperature setting up to 85˚C (1˚C accuracy)
    • freeze protection (7°C)
    • economical temperature (55°C)
    • manual mode selection
    • water heater “On” or “Off “ selection.
  • Numerical display:
    • displays actual temperature in water heater
    • thermostat / thermometer sensor failure
    • extremely low temperatures
    • overheating (actual temperature exceeds 99˚C).

Indirect air heating elements – reliable operation, simple 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:

  • the heating elements 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.
