4. OPERATION

Tanks accumulate heat from the heating systems for domestic or industrial use. Dierent types of

boilers and heating systems, renewable energy sources (heat pumps, sun collectors) or electricity

can be used to heat the water in the accumulation tank.

Heat in the tank is accumulated either by ow of the heating liquid from the heat source or by ow

of the heating liquid and the heat transfer (e.g. from solar system) through the tubular exchanger,

or by warming by the electrical bodies installed inside the tank.

In the built-in D.H.W. tank or built-in instantaneous D.H.W. warming is the warmth accumulated

from the water in the accumulation tank.

5. INSTALLATION

The installation must be in conformity with the valid regulation and it can be done only by aqua-

lied specialist.

Faults caused by the incorrect installation, usage and operation cannot be considered as awarran-

ty case.

5.1 CONNECTION TO THE HEAT SOURCE

Place the accumulation tank on the ground, as close as possible to the heat source. Install the insu-

lation. Connect the heating circuits to all inlets and outlets as it is given in the table in the chapter 3.

Mount the deaeration valve at the highest place of the system and insulate all the connection

distributions.

5.2 CONNECTION OF THE ELECTRICAL HEATING BODIES

The accumulation tank can be accessorized with the electrical heating bodies. The electrical hea-

ting bodies can be connected to the electricity mains directly (body with an own thermostat) or

through the regulator of the whole heating system.

6. PUTTING INTO THE OPERATION

Fill the heating circuits with the appropriate liquids and deaerate the whole system. Check the

tightness of all the joints and the pressure in the system.

CAUTION: Accumulation tanks HR/HRS are lling as follow. The rst, will be lled inside

tank and then remainder of accumulation tank. In case of nonobservance of process the

inside tank can be damaged.

Set the parameters of the regulation of the heating system as it is given in the documentation and recom-

mended by the producer. Check the correct function of all control and regulation elements regularly.

uality of the heating water signicantly inuences the lifetime of the heating systems. Unsuitable qua-

lity of water may cause problems like the corrosion of device and creation of the limescale, especially on
