At the end of last years cold season our boiler started making a loud vibrating noise and we got a huge bill that was about $100 more than average. Right around that time we had a small gas leak, so I just attributed it to the gas leak. Also I changed the heat setting from 190-170 off-on to 170-150 off-on.

I can never tell exactly where the vibrating is coming from. For some reason it kinda hit me that maybe the pump is going bad. Would explain the boilers poor performance (cost) and the noise. The pump is a TACO 1/8hp model.

Can I unhook the pump and turn the boiler on to see if it is quiet. Boiler should fire up even though the water isn't circulating correct? Also any opinions on my 170 off and 150 on settings? maybe I should move it up a little?

Thanks a bunch.
