radiator tapping question

Timco

I am putting a larger rad in my basement b-room, and it has tappings from bottom to top diagonally. Question is, should supply be top or bottom tap? I am guessing bottom because heat rises and would heat rad better that way? 2-pipe. I have always piped across bottom but would like to not have to change the tappings on this.

I wouldn`t bother to change-it Tim,

The rad is going in the basement anyway(lowest point of system),,, with the proper circ to handle the flow through-it,,, your efforts to change the tappings will be a negligible gain at best.  ;-) 



PS- Just remember to add a drain-faucet if you ever need to,,,,,,,,,
