Fireplaces are notorious heat wasters because fire requires air to burn and the air comes from the heated air in the building.
There are higher efficiency fireplaces which can heat a building. Too much to go into here but study and investigate before designing and building it. Orient the house to maximize the view and put as much into the look as you can then insulate wherever possible. Insulation can be expensive if done wrong. Tendency is to overinsulate. Insulation installers rarely understand the thermdynamics of a building. Archietecs may be no better but a qualified designer will return their fee many times over. A vapor barrier is needed to retain moisture during the heating season. In architecture, estetics drive the designs and insulation as well as passive solar should be made to serve the needs in the completed building. Large glass areas can be insulated using thick glass with double or triple pieces. Rhomb walls and other passive solar techniques will store and thereby conserve energy in winter. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <sundial@uni-koeln.de> Sent: Thursday, September 04, 2008 4:14 PM Subject: sundial Digest, Vol 33, Issue 7 > Send sundial mailing list submissions to > sundial@uni-koeln.de > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.uni-koeln.de/mailman/listinfo/sundial > or, via email, send a message with subject or body 'help' to > [EMAIL PROTECTED] > > You can reach the person managing the list at > [EMAIL PROTECTED] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of sundial digest..." > > > Today's Topics: > > 1.
