Rais also has a standard air intake add-on for use in tight buildings.<BR>

</SPAN></FONT><BLOCKQUOTE><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>we need an air-tight wood stove for a passive house project. from a PH perspective, "air-tight" and "wood fireplace" may be oxymoronic. one could even say, "moronic" but that is another issue.<BR>
<BR>
nevertheless, the ideal unit would have a glass door, and a means of providing combustion air and a flue--which not only are "air-tight" but also allow air-tight damping close to the building envelope.<BR>
<BR>
what would seem optimum to me for combustion air would be a port on the side of the firebox that could mate with a standard pipe fitting. to that, standard pipe could run laterally to a side wall, and could be controlled by a gate valve just inside the wall surface.<BR>
<BR>
likewise, the flue damper would be located just under the roof deck, operated by a chain or cable.<BR>
<BR>
this would preclude having to insulate long runs of flue and supply pipe.<BR>
<BR>
Others have recommended products by Rais. One essential feature that Rais offers is very low heat output. The heat demand for this house will be miniscule.<BR>
<BR>
What about domestic products? All suggestions are welcome.<BR>
