What temps do you see out coming out of your boilers? I don't have a gauge on my stove pipe, but I checked with an IR thermometer and it never read over about 240 F. As it entered the flue pipe, just a few feet away, it read about 200. I also checked the supply pipe coming out of the boiler and the thermometer read the same as the mounted gauge so it seemed to be accurate. I was suprised to see these temps so low. Shouldn't they be higher? Are these temps inviting creosote? Thanks.
