in THE MAIN WALL
I am moving my radiators 4 inches off the walls to allow for insulation and drywall on the walls, in doing so I will have to add two 90 elbows on the inlet and outlet of rads. I can't get below the floor to come straight up. Will this effect the flow through the rads and if so can I put in a higher head circ. pump. Any help would be appreciated.

    Doubtful it will affect the flow significantly, but....

    Make certain you leave a vent ell to remove the trapped air serving the individual convectors, or you will wish you had never touched it :-)Each elbow is the equal of 3 linear feet of piping, Times 2 additional elbows equals 6 feet of equivalent pipe. It should not significantly affect the flow through the base board. Make certain you ream your pipes to full bore.ME

    Thanks

    Mark thanks for the information. Each rad has a bleeder vent on the outlet elbow. The supply line is  1 1/4 " copper pipe reduced to 1/2 " at the diverter tees. The rads sit about a foot above the supply line. Do you think this helps the situation.

    Thanks again
