The HTP HTP HTP HTP range of combined deposit tanks has the option of heating the storage tank by means of
an electrical resistor (optionally supplied by DOMUSA). The 1200W ceramic resistor (steatite) is
sheathed in the flange supplied with the kit. Thus, the resistor can be directly extracted from the
outside, without having to empty the storage tank, in a quick and clean operation.
A switch, a control
