sounds like you have a flow problem, did you flush down the system after installing your new rads (assuming they are extra rads).......did you balance the system...?

try turning off all the rads except the 2 new ones, and see what happens, if the warm, make sure the lockshield vlave is all the way open and the balance the rest of the system to suit...
