I have a problem with my water-water heat pump(type 668) and my stratified storage tank(type 4e).<br/></div><div>I try to heat my building model to room temperature(20°C) with floor heating and the heat pump. Between the two components, i have a storage tank.<br/></div><div><br/></div><div>Now the problem is that my heat pump provides a high load temperature but in fact i don't need a high temperature because a floor heating system doesn't<br/></div><div>need a high inlet temperature. Unfortunately type 668 doesn't have a parameter where i can set the outlet temperature. The only thing i can do is to reduce the<br/></div><div>parameter "boiling point" of water in my storage tank less than 100°C to have a moderate heat pump outlet temperature but i think it doesn't make sense because <br/></div><div>the boiling point of water is about 100°C. Now i wonder how i can control my heatpump to heat the water to the desired temperature. I guess the high temperature is depending<br/></div><div>to the boiling point of the storage, i think the heat pump always try to reach this point of temperature.<br/></div><div><br/></div><div>Thank you for your helps,<br/></div><div><br/></div><div>Best Regards,<br/></div><div><br/></div><div>Fahri Avci<br/></div><div><br/></div><div>TUM München<br/></div><div>Lehrstuhl Energiewirtschaft und Anwendungstechnik<br/></div><div>Arcisstraße 21 München<br/></div></div> <br><br><table cellpadding="0" cellspacing="0" border="0"><tr><td style="font-family:verdana; font-size:12px; line-height:17px;border-top:1px solid #000000">Ihr WEB.DE Postfach immer dabei: die kostenlose WEB.DE Mail App für iPhone und Android. <br><a href="https://produkte.web.de/freemail_mobile_startseite/"><b>https://produkte.web.de/freemail_mobile_startseite/</b></a></td></tr></table>
