First Rooftop Whole House Fan for Homes without Attics

Eichler was one of the most famous Mid Century Modern home builders in the 50s and 60s. His homes are all over California. Owners of his designs have not had a whole house fan to help cool their homes until now. I just invented the first rooftop to pull 8000 CFM at just 505 watts through a 20 inch throat. The top can be hidden by a chimney looking enclosure and the bottom inside the home by a faux cabinet.See more at http://www,/ThorwaldsonRooftopWholeHouseFans.com See More

Whole House Fan Thermostat

News for 2016! I have invented a thermostat for whole house fans that can be used on any installed fan. As you know, whole house fans should not be automatically started because there is no way to know if return air is available in the form of, usually, open windows. So my thermostat does not start working until the fan is turned on by the homeowner. Then it senses the home temperature and automatically turns the fan off when the temperature falls to the set point desired. More info at invisco…See More

"Hi Anthony, Ours was certified by The Florida Solar Energy Center.  You are right to say most of the spray on radiant barriers ARE junk.  We aint one of them.        "

Hello,

I am a whole house fan and attic ventilation expert in Temecula CA. I started studying whole house fans in 2008 when my wife, Darlene, and I moved from Manhattan Beach. I would really like to share my knowledge with all of you but I want to be sure I don't antagonize you with more commercialization than you want. Please let me know your opinion and if you can, send me some examples of acceptable blogs and unacceptable ones.
