Hi Gary, I did check the circ pump connections, and they are nice and
tiight, both at the pump and the AQ controller. (I also got nicely
electrocuted when messing with the controller when the burner was
But here we go again. Last might it was single digits, Bedroom
radiator was cranking nicely, but the rest of the house was 60 degrees
when I woke up, with 3 radiators cold.
The boiler is humming at 200 degrees (it only cycles off when it hits
the high limit on the aquastat) but the hot water is just not getting
to 3 of 8 radiators. I called the oil Co, they are sending out a tech.
I am going to bombard him with questions. I still think it may be the
circ pump. There is hot water, good pressure, no air in the lines, and
SOME of the radiators are getting very hot.
At least we may be getting somewhere, and boy I sure am getting an
education on my heating system...I mean, I had no idea what an aquastat
controller or circulation pump was three weeks ago.
Thanks - I will keep youy updated...
