−When the concentration of ch orides in the domestic water supp y exceeds 250 mg/dm3, we
recommend insta ing anti-corrosion protection inside the tank to prevent its premature
deterioration. DOMUSA

HTP range of combined deposit tanks has the option of heating the storage tank by means of
an e ectrica resistor (optiona y supp ied by DOMUSA). The 1200W ceramic resistor (steatite) is
sheathed in the f ange supp ied with the kit. Thus, the resistor can be direct y extracted from the
outside, without having to empty the storage tank, in a quick and c ean operation.
A switch, a contro
