<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">There is indeed a heat pump type DHW heater in eQUEST. Note that this is an air source heater with the condenser outside. As such, the COP diminishes quite
a bit from the rated value in colder climates. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">If instead you have a water source heat pump with a relatively stable condenser temperature and COP, I tend to model with an electric DHW heater with an EIR of
1/COP. <o:p></o:p></span></p>
