<DIV class=MsoNormal><SPAN lang=EN-GB>Hi All,<O:P></O:P></SPAN></DIV>
<DIV class=MsoNormal><SPAN lang=EN-GB>I would like to known which part of
solar and internal gains really participate to heating during winter for a
zone. <O:P></O:P></SPAN></DIV>
<DIV class=MsoNormal><SPAN lang=EN-GB>I mean with a heating system using a
temperature threshold, a part of these gain only contribute to increase
temperature above the setting. Then they don't participate to
heating.<O:P></O:P></SPAN></DIV>If you have an
idea....<BR><BR>Regards,<BR>JeFF<BR>
