Yes we have a furnace, but after reading about their lack of efficiency I want to have something better. I am planning to install the wall heater near a window because of the venting issue.
I don't think you have thought this through all the way.
If you vent properly to prevent moisture and CO buildup, I think you might very well end up with LESS gas efficiency than the furnace will provide you.
And you will have expended a LOT of time and money to accomplish little or nothing.
If you are going to cut into a wall, you could install a vented unit with a fan. But that would be roughly equivalent to the "furnace" that you already have.
I think you are putting WAY too much stock in those people who complain about the lack of efficiency with their stock furnace......and a perceived ability to fix the problem.
