Storage Water Heaters, horizontal or vertical fixing

Our range of storage heaters can be adapted to any space restriction due to the different options offered in sizes and capabilities. They have the following technical features:
  • 30-200 litre capacity.
  • Can be fixed in a vertical or horizontal position.
  • 2x separated and sheathed electric resistances, which means water heater performance can continue if one of the resistances fails. Lifetime will be longer because water chemical components will not be in contact with them and will not affect them. These heating elements can be replaced without emptying the water heater. Heating elements are bent at a certain angle in order to reduce the water heating time when the device is installed in a horizontal position, achieving a higher energy efficiency.
  • The exclusive water inlet diffuser allows a smooth and soft water entrance to the tank, avoiding the water mixing and optimizing the heater performance.
  • Steel tank with a Titanium double lined 850ºC vitrified enamel
  • Magnesium anode.
  • Dielectric fittings.
  • External control thermostat.
  • Built-in control thermostat to manage water temperature.
  • Luminous indicator.
  • Safety non return valve.
  • Optional supporting tripod.
  • Optional supporting fittings for ceiling installation.
  • Also available in a reduced diameter with only a 38cm diameter for smaller spaces.

Low Capacity & Compact Storage Heaters

This range has been developed to fit installations which need hot water very quickly (kitchen, shower, garage, doctor’s surgery etc.) and are the most compact of all storage water heaters, suitable for both under or over sink fittings. Their technical features are as follows:
  • Tank of vitrified steel.
  • Magnesium anode
  • Safety valve and insulating dielectric hoses
  • Shielded elements.
  • External control thermostat.
  • Luminous indicator.
