You are going to have to find someone familiar with boilers to come out and look at it. Based on your question, doing it yourself is beyond your abilities. These ALL need periodic maintenance or they will fail.

Agree with smoothy. Time to get a heating/boiler tech in. They will be able to determine the cause of your lack of heat. It may be an easy fix, but will require the knowledge of a trained professional.
