Hanging Hydronic fin tube baseboard

KubwaJack

I Started the Plumbing and Heating trade in 1964 in upstate NY. I received my Masters license in 1973. I now live in Mass. and hold an up to date Journeyman license. So, I have done a good bit of work in the 50 + years that I have been at it.
I was taught early on ,when installing the back panel for base board hydronic fin tube, like Slant Fin , Haydon etc., you always hang it 3/4" off the floor unless the room is to be carpeted and then it would hang 11/2" off the floor for proper circulation thru the fins.
I was recently told by a Carpenter that this is all wrong and ALL baseboard should touch the floor !

My Question to the community is , " am I all wrong after doing this with happy customers for over 50 years " ? Who is correct ?

Thank you for your help,
Jack

You are correct.

I just installed Sterling baseboards throughout my house, and the instructions that came in the box with the baseboards show them being installed resting on the floor. I put mine about 3/4 inch above the finished floor so I could get the vacuum underneath them.

Had to be installed higher in the 70's !!

I miss those shag rugs. They were tough on the lawn mower, though.

Pretty common cause of insufficient heat calls!

You sir , are in fact correct

The gap between the cover and the bottom of the actual assembly should be plenty to allow air flow.

I like 3/4 above the floor.

If you raise them up higher then you need to rip down the wood baseboard trim and install it below the BB, or you see unfinished wall and sheetrock.
The sheetrock rarely goes to the floor as the installers use those foot lifters to squeeze it tight to the ceiling.
