models with identical building geometry and envelope. One is induction unit and
the other is ground source heat pump. I have manually entered baseboard
capacity for each zone and kept them identical between the models. My peak loop
load is the same but my GSHP model has about 25% higher annual load/energy. I
have checked several things – envelope, misc loads, lighting, <span

have higher baseboard energy.<o:p></o:p></span></font></p>
