3.6 Domestic hot water requirements<br />
Heating water<br />
In the past there were some norms<br />
how to fill heating <strong>system</strong>s <strong>with</strong> the<br />
usual local domestic water. The variety<br />
of materials used in heating <strong>system</strong>s<br />
today requires a precise <strong>an</strong>alysis of the<br />
compositi<strong>on</strong> of the hot water used, <strong>an</strong>d<br />
<strong>an</strong> appropriate preparati<strong>on</strong> where required,<br />
to prevent unw<strong>an</strong>ted build ups<br />
<strong>an</strong>d corrosi<strong>on</strong>.<br />
Scale, which occurs at specific temperatures<br />
<strong>an</strong>d c<strong>an</strong> build up <strong>on</strong> the elements<br />
of boilers or heat exch<strong>an</strong>gers, is <strong>on</strong>e<br />
of the “problem subst<strong>an</strong>ces” in hot<br />
water. Such deposits impair the heat<br />
ex ch<strong>an</strong>ger’s efficiency <strong>an</strong>d perform<strong>an</strong>ce<br />
capacity, cause higher return temperatures<br />
<strong>an</strong>d therefore reduce energy<br />
efficiency.<br />
The use of suitable specialist comp<strong>an</strong>ies<br />
is recommended for the <strong>an</strong>alysis <strong>an</strong>d<br />
preparati<strong>on</strong> of the hot water. The pH<br />
value should also be checked regularly.<br />
