    Somehow you're post got cut off -- but the little that did post is cause for a good deal of concern. 2 gallons per year might be very reasonable. 2 gallons every two days is going to kill you boiler rather quickly, if it hasn't already.

    You have a significant leak somewhere. Look for steam coming out the chimney for starters when the boiler is running. Then check all the wet returns -- all the piping below the water line -- for leaks. Then turn the boiler off and let it sit. Mark the water level after half an hour, and then go down again after a couple of hours and check. The water level should not have gone down at all. If it has, there is a leak, and if it is not in a wet return, it's in the boiler itself below the water line.

    @alano9999. In addition to what Jamie said. Shut boiler. Fill the boiler until water reaches top of glass plus another 90 seconds. Look and listen for water dripping. This is to check for leaks on the top portion of the boiler.

    If your boiler is not leaking the most common cause of loosing water is a leaking wet return pipe (if you have one...some jobs don't). Look around your boiler and see if you have any pipes that go down into the floor. If you do look around the basement for another pipe going down into the floor which would be the other end of this pipe
