One concern though is getting very much air out of your newly added vent. You used a straight T fitting, should have been a "T-Wye" fitting, kind of looks more like a Y than a T. If you have both vents wide open you might not get much air into the bathroom as there's more pressure drop there than straight through. But then again you don't need as much air in a small bathroom so it might just work out O.K. I bring this up as HVAC is my business.

C'mon now. The bathroom? This is a very small space and the back pressure from the bedroom will provide more than enough heat to the bathroom.

I tested the furnace today and found that the volume of air coming out of the bathoorm and bedroom vent are pretty much the same. Closing off the bedroom vent doubled the volume coming out of the bathroom vent. I think it's going to work pretty well...

I considered that so, I replaced that bedroom heater vent with a adjustable one that I can completely close off or adjust so adequate flow goes into the bathroom. At night when sleeping I can reverse that. The Y instead of a T would have been a good idea...

I was thinking the same thing. I'm even more anal, I would have included a damper going to the bathroom as well.

4" T
4" Ducting
4" couplers
2 4" adjustable heater grills
metal duct tape

The ducting in the vanity


Splice into the ducting add couplers


Add T and connect duct


Drill hole for heater grill


Attach ajustable grill


I also added a adjustable grill to the bedroom heater vent where if needed I can close off part of the bedroom to force heat to the bathroom

You are right about that. I took that photo from my photo library and was not paying attention. I corrected the connection when someone else pointed it out.

This is how its suposed to look

Your batteries are not balanced. You're going to destroy that lead battery. You need to move the negative lead to the opposite end battery post and that will balance your battery bank.
