Corrosion Protection
Inner cleaning of the tank with automated sand blasting (not chemically) resulting in a perfect adherence of the enamel. Food grade enamel quality applied with a “double direct” method and baked at 850° C. Extra corrosion protection is offered by magnesium rods that must be checked and replaced if necessary every 2 to 5 years, depending on the quality of the water.

Backup Heating Source
If solar power is not sufficient to warm the water, a backup heating source can be used, either through an electric element or another heating source (central heating burner) that will be connected to the upper heat exchanger (BL2 models). Control of the electric element is made through the built-in thermostat. It is recommended the thermostat be positioned between 50° C and 60° C during winter months and between 45° C and 50° C during summer.

Thermostat: model COTHERM type TUS T115

  • Regulation: between 30° C - 80°C
  • Contacts: bakelite – silver
  • Protection cap from nylon 6 (flame retardant).
  • 230 V /20 A

Backup Heating Source Using the Second, UpperHeat Exchanger
Coil type heat exchanger, from heavy duty steel (type Tubo) integrated in the upper part of the tank, in order for the secondary heating source to heat only the upper part of the tank. Further technical data concerning the upper heat exchanger refer to the table concerning BL2 tanks.
