You should not have to add water daily. I have a Bryant BS2 boiler, which only drops an inch or two in a matter of weeks, and I do not let it get low enough for the automatic water feed to kick in.
Make sure that your pressuretrol is set as low as it goes (outside indicator at 0.5 psi and inside dial at 1). Your system should cycle the burner off at 1.5 psi and on at 0.5 psi. If that is set too high (or pigtail is plugged), your system will not be efficient and air vents may not operate properly. Previous owner had mine cranked way up due to faulty vent damper (would stick closed when hot). I replaced vent damper, dropped pressure down, and repacked any radiator shutoff valve stems that were leaking, and replaced any air vents that were not working properly.
Don't necessarily believe your pressure gauge. When my boiler was 2 years old, the snubber on the gauge was totally blocked (just reading trapped air pressure).
There is no telling from here what may have been neglected, gunked up, or set too high.
