Θερμοσίφωνας διπλού τοιχώματος, 20 λίτρα χωρητικότητα

Whilst conventional calorifiers use a spiral tube to heat the water, these calorifiers use a very efficient double wall principle. Thanks to this double wall principle, the VETUS double wall calorifiers have a heating surface, which is much greater than that of a conventional heating spiral tube. This means that the double walled calorifiers will heat the water significant faster than conventional calorifiers.
