I guess my main motivation for wanting to go with the tankless is space and mounting options. 

Aircraft hangers are extremely passive .. and many are rented to very high net worth type folks who keep their car collections in them build a man cave in them.. have their million dollar motor home in them.. and of course their aircraft.I bought our hanger it was a condo project.. so we have an HOA and a ready room.. but if I look at my neighbors one is Warn winch's they have a 3 hanger set up   a Citation jet  a Beech 1900  a war bird  a L 39  single pilot jet trainer motor home car collection boats you name it.. 

I've done pendent lights, flush mount fixtures and can light rims.  

The original purpose of a motor inn of yester-year was to serve the area's cold war patriots from the Sav.

@Dan Travieso try L&E Properties based out of mount Holly.

I use a knob-mounted box, its $30 at home depot.

I will be mounting a rent box in the building this week for there convenience.

I give them 3M tabs for mounting pictures also which saves your walls especially if you have plaster !

@Ashish AcharyaGive me a shout post 4/15.Right now I generally get on BP in-between clients to de-stress a little.Not a good time to get into a debate and dive into code sections.Perhaps my most recent example was too hasty reviewing the regs right now...The "-3" reg defines structural components by reference to Treas Reg Sec 1.48-1.The term “structural components” includes such parts of a building as walls, partitions, floors, and ceilings, as well as any permanent coverings therefor such as paneling or tiling; windows and doors; all components (whether in, on, or adjacent to the building) of a central air conditioning or heating system, including motors, compressors, pipes and ducts; plumbing and plumbing fixtures, such as sinks and bathtubs; electric wiring and lighting fixtures; chimneys; stairs, escalators, and elevators, including all components thereof; sprinkler systems; fire escapes; and other components relating to the operation or maintenance of a building.We know that a building and building structures are a single unit of property.  

I don’t believe the digital wall mounted controller is operated by batteries.
