STORAGE TANK -> DHW storage<br />
Benefits:<br />
• Contained costs<br />
• Once the entire storage tank is <strong>heat</strong>ed up a large volume of<br />
DHW is available<br />
• Good stratification also in the withdrawal phase («syringe<br />
effect»)<br />
USERS<br />
AQUEDUCT<br />
Disadvantages:<br />
• Requires an anti-legionella cycle<br />
• The <strong>pump</strong> operates with a reduced volume of water-> «Plugging» risk on the coil: if the<br />
<strong>heat</strong> <strong>pump</strong> is not able to transfer the entire power through the coil the technical water<br />
returns to the unit too hot and the <strong>heat</strong> <strong>pump</strong> will stop -> risk of switching on/off too<br />
frequently<br />
• Reloading times can be long (there is an interposing coil)<br />
• Not the best T approach between technical water and DHW (Delta T approximately 5°C)
