Gas boiler problems

[Adam Montone]

I’m having problems with my gas boiler not heating properly. The temperature only goes up to 140 and continues running constantly? Any ideas? Its ran all day and never shut down. I finally shut it down as it wasn’t putting out enouogh heat to the baseboards.

There is no way to be sure from the given information, but the most likely cause is a change in the gas input probably due to a pressure reduction. If the system always was that way, there is another reason. You need an experienced gas fitter/plumber to inspect your combustion system.

Chessnut,
Check the temperture setting
in aquastat,most likly set
too low. Should be set
around 180-190f for proper
heat output

Chessnut,
Boiler has limit control for
temp, could be set too low.
Check setting, should be at
180-190f.This should take care
of problem.

Chessnut,
High limit setting may be set
too low,should be 180-190F for
heat output at baseboard to
give off enough heat.

looks like were missing some replys here. I can’t help wondering if maybe they were removed because they had different opinions then the chosen few.

Could be that some are missing Kenny. A high limit aquastat set too low would shut the burner off because of reaching the low setting. This person says the burner runs all day.
