4.5 Equipment / options
Although Sanit units are equipped with all the necessary components for functioning, DOMUSA
TEKNIK offers several optional components for cases in which special features are required.
4.5.1 Cathodic protection
If the chloride concentration in the domestic
hot water is higher than 250 mg/cm
3
, we
recommend installing a cathodic protection
inside the storage heater to avoid premature
wear to the hot water tank.
DOMUSA TEKNIK
optionally supplies a suitable electronic
cathodic protection for its range of storage
heaters. To install it, carefully read the assembly
instructions supplied with the cathodic
protection.

4.5.2 Electrical element
All Sanit hot water tanks have a socket for
connecting an electrical element.
DOMUSA
TEKNIK optionally supplies three elements, of
1.5, 2.5 and 3.5 kW. To install them, carefully
read the assembly instructions supplied with
the elements.
Figura 2
4.5.3 18L DHW expansion tank.
Due to the increase in the temperature of the
hot water stored, the pressure in the hot water
tank increases, and
DOMUSA TEKNIK therefore
optionally offers this DHW compensation tank
for the Sanit 300, 500, 750 and 1000 models. To
install the tank, carefully read the assembly
instructions supplied with it.
