Pressurised electric water heaters

These heaters are recommended for situations where at least two water outlets are to be supplied with hot water. They are most suitable for refurbishing old buildings, laundry rooms, kitchens, laboratories and workshops. The heater can be converted to the non - pressurised version for one single outlet at any time, with proper connection of the mixer tap.

The tank is manufactured from a steel sheet, coated with a high-quality anticorrosion enamel in combination with a protective magnesium anode.

ADVANTAGES:

  • Volumes: 5, 10 and 15 l.
  • Supply of two or more outlets.
  • Under basin and over basin mounting option.
  • Tank made of high-quality sheet steel, enamel coated at 850°C.
  • Magnesium anode for additional anti-corrosion protection of the tank.
  • Insulated version of heating flange.
  • Optional setting of water temperature up to 75°C.
  • Possibility of selecting an economical water temperature and freeze prevention temperature setting.
  • Indicator of electric heating element operation.
  • Can be used as a non-pressurized unit if properly connected and fitted with a mixer tap.
