The average outdoor temp since sunup, has been about 40F
(it's only 42F right now, in the later part of the heat of the day)!

Last 24 Hours Weather: , read this fast, before it changes!

My attic temp right now is 66.4F (overnight min=40.9 max=68.0).

So, 66.4 - 42 = 24.4 deg F of difference (at this second)..


Anyways, since we had Sanyo #1 set for 68F most of the day,
when we were heating, the addition of some warmer air to the intake
would have likely mean less watts would have been used..



Would there be a break-even point within 5 or 10 years??
What does your kW hours cost you? Are you using PV and a GTI?
(I've been running this PC on solar all day).

Since I'm using high performance heating machines already,
I would be somewhat reluctant to add-on a hack like this, for a small gain.
Even if it saved 15%! That's not a heck of a lot of money,
when you are only burning 60-70 bucks a month on heating..
(We spend more than $60 on candle-pin bowling)! Prices
Heck, we could cut out bowling and our heat would be "free".. LOL!!

My heating cost is ready way lower than anyone else on this side of town...

And, another large duct down the side of our house would not likely be approved by my wife.
