makeup air dumper to range hood

The system is AC only so for 6 months a year it's not running and the air getting pulled in from outside would be unconditioned for those 6 months. Although some of that air would go through the AC supply ducts a majority of it would likely get pulled through the return duct which is on the second floor. So in mind that would be equivalent to opening a window in the middle of the house when it's 10° outside.

JMO but isn't really much different than an ERV unless there is short path from inlet to some register and you actually will feel that cold air easily.

logic tells me ERV doesn't exactly recover the energy it is just more of place to condition incoming air utilizing the ambient air already inside, you still have heat gain or loss depending which side of things is the higher temperature. If you use a duct heater on the intake you still adding energy to replace what you lost out the exhaust. The only way to minimize heat gain/losses is to place the make up air as close as possible to where you are exhausting ambient air from.

My thought as well which is why I'm considering a separate MUA system. I was looking at a Fantech system but the cost is pretty outrageous considering what you're getting.
