Just put in an order today.

It will be an experiment to see how much it reduces my heating costs this winter. If it does even a bit, then great! Otherwise, I'll essentially be paying the hyrdo comoany to DCA for me.

My strategy is going to be to leave it in the livingroom next to my furnace air intake and basically leave the central heating thermostat to do it's thing. If the a9 it's running 24-7 then the furnace won't kick in as much. If it gets too toasty I can crack a window. Probably in the spring I'll have to give her a break until next winter.

I'm wondering how it will affect humidity, if at all.

Also not sure how the girlfriend is going to react.

Lots to learn! Thanks for the input anyway.
