    long run time on intial start up

    Does it normally take an hour for the primary water temp to come up to 160degrees. I have a large volume of water( 120,000 btu of radiators) and 100' ++ of 2"iron pipe. A longer run cycle is a good thing correct? It should in effect satisfy the t-stat on a milder day without reaching a higher temperature??? And when the out temp requires peak load a longer run cycle should raise my water temp enough to satisfy those peak loads?? Am I correct here? The water in my only common piping seeemed to be neutral( circ on the secondary side robbed nearly all of primary water. Upon start up secondary return temp was around 75f and supply 90f. After an hour secondary return 137f and supply 160f. Is this normal? Note: Yes the stat was jumped out.
