Location
The hot water tank must not be installed outdoors or in a place where it may be exposed to weather
inclemencies.
To optimise energy use, the hot water tank should be installed as close as possible to the hot water
generator.
When choosing a location, taken into account the weight of the full hot water tank, and make sure it
is protected against frost. The pipes should be lagged in compliance with heating regulations.
For wall-mounted and horizontal installations, ensure the type of wall to which the hot water tank is
fixed can withstand the weight of the tank when full, and choose the most suitable fixing system
depending on the wall in question.

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
S 200 and Sanit S hydraulic kits
Due to the increase in the temperature of the
water stored in the hot water tank can cause
the pressure in the tank to increase. DOMUSA
TEKNIK therefore recommends fitting the
S 200 or Sanit S hydraulic kit consisting of
dielectric sleeves, a DHW expansion tank and
a safety unit, to protect the hot water tank. To
install it, carefully read the assembly
instructions supplied with the kit.
