Boiler not firing, no ch or hot water now

[seco services]

open all the rads.
you are looking in the small tank.
that system should be red hot by now. sounds like it needs a cleaning chemical running through it.

if its not tripping i would leave it running on its own or you'll be sitting there all night, and i got to get up early. LOL

but i think it sludged up and getting bad circulation.
