<strong>Solar</strong> <strong>Indirect</strong> <strong>DHW</strong><br />
<strong>Heating</strong> <strong>Storage</strong> <strong>Tank</strong><br />
Logalux PL750/2S<br />
Thermosiphon Combi-<strong>Tank</strong><br />
Internal <strong>DHW</strong> storage tank, conical straight through design, with Buderus<br />
thermoglazing and magnesium anode for corrosion protection<br />
Patented heating lance for stratified storage tank heating, surrounded by <strong>DHW</strong><br />
and running along the entire column of the storage tank<br />
<strong>Solar</strong> indirect coil integrated in the heating lance and therefore also surrounded<br />
by <strong>DHW</strong><br />
Significantly improved solar efficiency because the solar heating system always<br />
heats the coldest water first<br />
All connections for heating are on the storage tank side<br />
<strong>Solar</strong> coil connection and cold water inlet from the bottom<br />
