I need to get my boiler checked. I'm hoping the gage is just wrong, because it only shows water temp of 120, I think its supposed to be 180. Its always kicking on, so I think it is working, but the house never gets much above 66 when its colder than 40 out. I do not have insulated windows though, so I'm sure I'm loosing a lot of heat that way. Burned through 400gal of propane this winter, and the boiler is the only thing using it.
