Gas boiler shuddering and ticking

Member Posts: 1
I have a gas boiler in my basement. It has 4 thermostats. I recently reversed the direction of flow. Now the hot water reaches the individual heaters first in it's circulatory path and the circulator is on the hot (output) side of the boiler. But as the boiler reaches about 140 degrees it shudders. like water hammer? or an obstruction? Kind of a muffled tinging sound. Don't know. I tried only running one branch (one thermostat) at a time, to isolate it, but the noise seems to occur in all branches as it reaches about 140 deg. I also drained it down quite a bit and let fresh air back into the air tank and refilled the system. But the water hammer noise seems to persist.
Does anyone know if this is dangerous or going to cause leaks down the line? Anyway it's just plain kind of noisy.
Previously the water went to the second floor of the house first and then it would drop back down to the main floor where all but one baseboard heater is. It was giving up so much heat energy before it ever reached the heaters and the energy bill was so high so I had to reverse it.

just an idea
I recently received a service call for a similar situation an discovered the installer had put the pump on the output piping but pumping the wrong way causing the water in the top of the boiler to reach temps excedding 235 degrees yet the water at the guage and hi-limit to be below the set temp of 190. just something to check.

Is there a flow check? And now could it be in backwards?0 -
How did you reverse the flow
do you have zone valves, if they are in backwards they can cause water hammer.
Did you reverse the flow through the boiler, if so you now have cooler water coming in were the aqua-stat is so the boiler is reading the wrong temperature.
Did you do the work yourself or hire a contractor.

Why?
OK, I will be the first to ask.
Why did you reverse the flow through the boiler?

The aquastat is reading return temp and letting the boiler boil water ? possibly0
