    Advice for stuck aquastat bulb

    Hey walliens.  I've got a stuck bulb, I removed the well and replaced the aquastat, but the stat is still good, I just wanted to free it from the 1/2" well and use it in my own place.  I've soaked it with WD40 but the heat conducting compound seems to not let go.  Should I try to heat it up?  I don't want to get it too hot for obvious reasons.  Just wondering if anyone had success with some method.

    Filling the well with oil and then heat. Put it in a vice or something to hold it up.

    hot rod wins

    pipe cutter works well, take your time I cut them about an inch in then you should be good, or install the entire thing in your system...

    That's what I did.  I had a well in already but trying the heat and oil bit and risking damaging the capillary if I worked it any more, I just drained the system and bushed the 3/4 tapping to 1/2 and threaded the whole thing in.  Problem solved, and free used parts from a boiler I removed from a customer's apartment building.

    gotta love free parts

    I had a customer that had me remove a 3 year old peerless oil fired boiler and indirect, and a 2 year old 275 ga oil tank {installed a gb and rinnai unit}, they also had me remove all the baseboard and install 2 hydro airs with a/c...
    I bought a property about a month before that, it was a forclosure and they ripped out the boiler, water heater, all the copper and baseboard... I moved that customers stuff rite from his walkout to that basement, installed it all rite down to the copper tubing that I removed from their house and replaced with pex to their air handlers.... I even used their 1 1/4" pipe for the vent and fill.... Free heating systems never hurt...

    Also when I pull out boilers with good circs, boilers, and controls, I keep them parts for customers that can not afford new parts...
