victor, You're right, a motor whether A.C. or D.C. takes just so much power to operate it, about 750 watts per horse power or so. doesn't matter a dime whether it's A.C. or D.C. Except that the power feeding your furnace is A.C. and has to be rectified to make it D.C. some efficiency lost there I suppose.
it can be said that the power consumed by the fan is a very small portion of that consumed by the entire furnace, but it still costs power to run the motor. What you'd accomplish with running the fan all the time depends on where the return intake is. If, for example, the return intake is in a part of the house that tends to remain cooler, then perhaps you'd move cooler air around better. I had a friend who had a "summer' return intake put into his basement. He didn't have air conditioning, but when it was summer and he switched the intake to the basement port and just ran the fan as needed, the house was much cooler than one would expect. However, i always wonder about advice from guys in government sponsored programs. They're usually just contractors who have low bid on the city job, and are probably looking for more work. I wouldn't do it without another opinion. tom Net-Tamer V 1.13 Beta - Registered To listen to the show archives go to link http://acbradio.org/handyman.html or ftp://ftp.acbradio.org/acbradio-archives/handyman/ The Pod Cast address for the Blind Handy Man Show is. http://www.acbradio.org/news/xml/podcast.php?pgm=saturday The Pod Cast address for the Cooking In The Dark Show is. http://www.gcast.com/u/cookingindark/main.xml Visit The Blind Handy Man Files Page To Review Contributions From Various List Members At The Following address: http://www.jaws-users.com/handyman/ Visit the archives page at the following address http://www.mail-archive.com/blindhandyman@yahoogroups.com/ For a complete list of email commands pertaining to the Blind Handy Man list just send a blank message to: [EMAIL PROTECTED] Yahoo!
