<div dir="ltr">in a recent project for other pyrophilic clients, (and despite all my hand wringing to them) I spec'd a wood stove by Napoleon: <a href="http://www.napoleonfireplaces.com/products/nz26-zero-clearance-and-masonry-fireplace/">http://www.napoleonfireplaces.com/products/nz26-zero-clearance-and-masonry-fireplace/</a><div><br></div><div>even with that gratuitous feature (and a conventional clothes drier) the house came in below 0.6 ACH@50 PA. One nice feature is that the stove has provision to route air heated within its jacket to remote locations, so the occupants don't collapse from heat prostration while it's in use. In the subject case, hot air was ducted to a point adjacent to the heat pump return (direct connect is prohibited by the mnfr)</div><div><br></div><div>one thing to bear in mind is that the length of the flue, even with a roof top damper, represents an ambient or near ambient condition. applying insulation directly against the flue is prohibited, so an insulated chase was provided instead.</div><div><br></div><div>-AA<br><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><font><font><span style="color:rgb(102,0,0)">Alan Abrams</span></font><b style="color:rgb(102,0,0)"><br></b><i><span style="color:rgb(102,102,102)">certified professional building designer, AIBD<br>certified passive house consultant, PHIUS</span></i></font><div><i><span style="color:rgb(102,102,102)">certified passive house builder, PHIUS</span></i><font><span style="color:rgb(102,0,0)"><font color="#666666"><i><br></i></font></span></font><font style="color:rgb(102,102,102)" size="1"><font>cell </font></font><font style="color:rgb(102,102,102)" size="1"><font>202-437-8583</font></font><font style="color:rgb(102,102,102)" size="1"><font><br>
