Boiler temp not reaching aquastat
I’ll start by saying I recently had my boiler converted from Oil to gas . And i knew with the oil burner that the water temp would reach the temp set on the aquastat and then shut off which is 180. But after gas burner installed, right away I noticed water wasn’t get much over 150. But the aquastat would respond if I turned it up that water temp would warm up by whatever amount I increased it. Could there be an problem with the aquastat or temperature gauge? The person who installed the gas had came back for some other issue and I asked about this and they didn’t seem to notice any issue.
