Go to Grainger.com search for blower fans, look for Dayton 4C440. That is the
standard blower motor used to inflate most of the poly greenhouses in the
country. They consume around 45 watts. I run them 24/7 they last 6-8 years.
Mount them so they draw air from the outside of the house never the inside. 
You
only need to inflate 1/2 inch to get all the benefits of insulation. The 
blower
will not be large enough to keep the poly on a house your size very tight to 
the
wind... Bob.
