Hey Thanks everyone for the info! turns out i have a 3speed blower! the lowest speed is perfect. the highest speed is like a tornado

One thing to be aware of is the amperage draw. I have no idea about the efficeincy of that blower. It may be worth while in electrical bill savings to save for an inline blower. Any electrical device should have a sticker on it that tells you the amperage draw at the different speeds. For a benchmark, my Elicent 636 cfm fan is rated at 120 watts (I'm pretty sure). 120 watts is...

voltage/watts = amperage

120v/120 = 1 amp

If you buy the blower seperately, you'll get a spec sheet with it, but if it was salvaged from an old furnace, it isn't likely to be individually listed. If you know the modle number of the furnace, you maybe able to find a spec sheet on the internet.

The use of a Programmable Thermostatic Outlet can loweryour consumption rate by switching the unit on and off according to a set tempeture range. They can be used for heating and cooling

where would i get a rheostat? and roughly how much would it cost?
